UL Benchmarks Updates 3DMark with Ray-Tracing Feature Test

The launch of AMD Radeon RX 6000 Series graphics cards on November 18 will end NVIDIA's monopoly on real-time raytracing. For the first time, gamers will have a choice of GPU vendors when buying a raytracing-capable graphics card. Today, we're releasing a new 3DMark feature test that measures pure raytracing performance. You can use the 3DMark DirectX Raytracing feature test to compare the performance of the dedicated raytracing hardware in the latest graphics cards from AMD and NVIDIA.

Real-time raytracing is incredibly demanding. The latest graphics cards have dedicated hardware that's optimized for raytracing operations. Despite the advances in GPU performance, the demands are still too high for a game to rely on raytracing alone. That's why games use raytracing to complement traditional rendering techniques. The 3DMark DirectX Raytracing feature test is designed to make raytracing performance the limiting factor. Instead of relying on traditional rendering, the whole scene is ray-traced and drawn in one pass.

Intel Storms into 1080p Gaming and Creator Markets with Iris Xe MAX Mobile GPUs

Intel today launched its Iris Xe MAX discrete graphics processor for thin-and-light notebooks powered by 11th Gen Core "Tiger Lake" processors. Dell, Acer, and ASUS are launch partners, debuting the chip on their Inspiron 15 7000, Swift 3x, and VivoBook TP470, respectively. The Iris Xe MAX is based on the Xe LP graphics architecture, targeted at compact scale implementations of the Xe SIMD for mainstream consumer graphics. Its most interesting feature is Intel DeepLink, and a powerful media acceleration engine that includes hardware encode acceleration for popular video formats, including HEVC, which should make the Iris Xe MAX a formidable video content production solution on the move.

The Iris Xe MAX is a fully discrete GPU built on Intel's 10 nm SuperFin silicon fabrication process. It features an LPDDR4X dedicated memory interface with 4 GB of memory at 68 GB/s of bandwidth, and uses PCI-Express 4.0 x4 to talk to the processor, but those are just the physical layers. On top of these are what Intel calls Deep Link, an all encompassing hardware abstraction layer that not only enables explicit multi-GPU with the Xe LP iGPU of "Tiger Lake" processors, but also certain implicit multi-GPU functions such as fine-grained division of labor between the dGPU and iGPU to ensure that the right kind of workload is split between the two. Intel referred to this as GameDev Boost, and we detailed it in an older article.

AMD Radeon RX 6000 Series Specs Leak: RX 6900 XT, RX 6800 XT, RX 6700 Series

AMD's Radeon RX 6000 series graphics cards, based on the RDNA2 graphics architecture, will see the introduction of the company's first DirectX 12 Ultimate graphics cards (featuring features such as real-time raytracing).

AMD "Big Navi" GPU Die Pictured? Allegedly Measures 536mm²

Coreteks, in a video presentation on Sunday, released what is possibly the very first picture of the AMD "Big Navi" GPU silicon, which could power the company's next-generation Radeon RX 6000 series flagship graphics card. The grainy, blurry-cam picture reveals a mostly square package with a large, rectangular die at its center, which Coreteks estimates to be 536 mm² in die-area, with 29 mm x 18.5 mm (LxW) dimensions. The channel used an unusual method for measuring the die size. The chip is rumored to feature around 80 compute units based on the RDNA2 graphics architecture, which includes fixed-function hardware for real-time raytracing, as RDNA2 is designed to meet DirectX 12 Ultimate logo requirements. We'll know more about the chip in the run up to its October 28 unveiling.

NVIDIA Will Stop Creating SLI Driver Profiles After January 2021

NVIDIA has been limiting SLI support recently with only the RTX 3090 featuring support for the feature and even then only through modern APIs such as DirectX 12 and Vulkan meaning that games must explicitly support SLI to work. NVIDIA will no longer be adding new SLI driver profiles on RTX 20 Series and earlier GPUs starting on January 1st, 2021. The only way to use SLI going forward will be through native game integrations which NVIDIA will focus on helping developers provide. NVIDIA also noted that various DirectX 12 and Vulkan games already feature native integrations such as; Shadow of the Tomb Raider, Civilization VI, Sniper Elite 4, Gears of War 4, and Red Dead Redemption 2. Creative and other non-gaming applications that support multi-GPU acceleration will continue to function across all supported GPUs.

Microsoft Rolls Out DirectX 12 Feature-level 12_2: Turing and RDNA2 Support it

Microsoft on Thursday rolled out the DirectX 12 feature-level 12_2 specification. This adds a set of new API-level features to DirectX 12 feature-level 12_1. It's important to understand that 12_2 is not DirectX 12 Ultimate, even though Microsoft explains in its developer blog that the four key features that make up DirectX 12 Ultimate logo requirements were important enough to be bundled into a new feature-level. At the same time, Ultimate isn't feature-level 12_1, either. The DirectX 12 Ultimate logo requirement consists of DirectX Raytracing, Mesh Shaders, Sampler Feedback, and Variable Rate Shading. These four, combined with an assortment of new features make up feature-level 12_2.

Among the updates introduced with feature-level 12_2 are DXR 1.1, Shader Model 6.5, Variable Rate Shading tier-2, Resource Binding tier-3, Tiled Resources tier-3, Conservative Rasterization tier-3, Root Signature tier-1.1, WriteBufferImmediateSupportFlags, GPU Virtual Address Bits resource expansion, among several other Direct3D raster rendering features. Feature-level 12_2 requires a WDDM 2.0 driver, and a compatible GPU. Currently, NVIDIA's "Turing" based GeForce RTX 20-series are the only GPUs capable of feature-level 12_2. Microsoft announced that AMD's upcoming RDNA2 architecture supports 12_2, too. NVIDIA's upcoming "Ampere" (RTX 20-series successors) may support it, too.

Intel "Tiger Lake" Gen12 Xe iGPU Compared with AMD "Renoir" Vega 8 in 3DMark "Night Raid"

Last week, reports of Intel's Gen12 Xe integrated graphics solution catching up with AMD's Radeon Vega 8 iGPU found in its latest Ryzen 4000U processors in higher-tier 3DMark tests sparked quite some intrigue. AMD's higher CPU core-count bailed the processor out in overall 3DMark 11 scores. Thanks to Thai PC enthusiast TUM_APISAK, we now have a face-off between the Core i7-1165G7 "Tiger Lake-U" processor (15 W), against AMD Ryzen 7 4800U (15 W), and the mainstream-segment Ryzen 7 4800HS (35 W), in 3DMark "Night Raid."

The "Night Raid" test is designed to evaluate iGPU performance, and takes advantage of DirectX 12. The Core i7-1165G7 falls behind both the Ryzen 7 4800U and the 4800HS in CPU score, owing to its lower CPU core count, despite higher IPC. The i7-1165G7 is a 4-core/8-thread chip featuring "Willow Cove" CPU cores, facing off against 8-core/16-thread "Zen 2" CPU setups on the two Ryzens. Things get interesting with graphics tests, where the Radeon Vega 8 solution aboard the 4800U scores 64.63 FPS in GT1, and 89.41 FPS in GT2; compared to just 27.79 FPS in GT1 and 32.05 FPS in GT2, by the Gen12 Xe iGPU in the i7-1165G7.

Nintendo Takes Legal Action Against Unofficial Super Mario 64 PC Port

An unofficial port of Super Mario 64 for PC was released on various online forums last week, this port was made possible through reverse engineering of the game's source code obtained by fans over the past few years. This PC port differed from existing options such as N64 emulation as it allows the game to run at far greater resolutions than its native resolution of 240p with resolutions such as 4K, 4K ultra-wide or even 8K now possible at uncapped frame rates. The DirectX 12 powered port came with other features such as controller support and the ability to add modern visual effects including ray tracing through third-party tools such as Reshade.

As expected Nintendo is not pleased with the port and has taken steps to get it removed from various sites, Nintendo has reportedly contracted US law firm Wildwood Law Group LLC who refer to the unofficial Super Mario 64 PC port as an "unauthorized derivative work based on Nintendo's copyrighted work." In addition to the download link takedowns, several YouTube videos featuring gameplay of the port have also been removed. Nintendo will want to get this port removed from the internet as soon as possible, especially given their plans to release new and remastered Mario games for the Nintendo Switch this year.

Intel iGPU+dGPU Multi-Adapter Tech Shows Promise Thanks to its Realistic Goals

Intel is revisiting the concept of asymmetric multi-GPU introduced with DirectX 12. The company posted an elaborate technical slide-deck it originally planned to present to game developers at the now-cancelled GDC 2020. The technology shows promise because the company isn't insulting developers' intelligence by proposing that the iGPU lying dormant be made to shoulder the game's entire rendering pipeline for a single-digit percentage performance boost. Rather, it has come up with innovating augments to the rendering path such that only certain lightweight compute aspects of the game's rendering be passed on to the iGPU's execution units, so it has a more meaningful contribution to overall performance. To that effect, Intel is on the path of coming up with SDK that can be integrated with existing game engines.

Microsoft DirectX 12 introduced the holy grail of multi-GPU technology, under its Explicit Multi-Adapter specification. This allows game engines to send rendering traffic to any combinations or makes of GPUs that support the API, to achieve a performance uplift over single GPU. This was met with lukewarm reception from AMD and NVIDIA, and far too few DirectX 12 games actually support it. Intel proposes a specialization of explicit multi-adapter approach, in which the iGPU's execution units are made to process various low-bandwidth elements both during the rendering and post-processing stages, such as Occlusion Culling, AI, game physics, etc. Intel's method leverages cross-adapter shared resources sitting in system memory (main memory), and D3D12 asynchronous compute, which creates separate processing queues for rendering and compute.

AMD RDNA 2 GPUs to Support the DirectX 12 Ultimate API

AMD today announced in the form of a blog post that its upcoming graphics cards based on RDNA 2 architecture will feature support for Microsoft's latest DirectX 12 Ultimate API. "With this architecture powering both the next generation of AMD Radeon graphics cards and the forthcoming Xbox Series X gaming console, we've been working very closely with Microsoft to help move gaming graphics to a new level of photorealism and smoothness thanks to the four key DirectX 12 Ultimate graphics features -- DirectX Raytracing (DXR), Variable Rate Shading (VRS), Mesh Shaders, and Sampler Feedback." - said AMD in the blog.

Reportedly, Microsoft and AMD have worked closely to enable this feature set and provide the best possible support for RDNA 2 based hardware, meaning that future GPUs and consoles are getting the best possible integration of the new API standard.

Microsoft DirectX 12 Ultimate: Why it Helps Gamers Pick Future Proof Graphics Cards

Microsoft Thursday released the DirectX 12 Ultimate logo. This is not a new API with any new features, but rather a differentiator for graphics cards and game consoles that support four key modern features of DirectX 12. This helps consumers recognize the newer and upcoming GPUs, and tell them apart from some older DirectX 12 capable GPUs that were released in the mid-2010s. For a GPU to be eligible for the DirectX 12 Ultimate logo, it must feature hardware acceleration for ray-tracing with the DXR API; must support Mesh Shaders, Variable Rate Shading (VRS), and Sampler Feedback (all of the four). The upcoming Xbox Series X console features this logo by default. Microsoft made it absolutely clear that the DirectX 12 Ultimate logo isn't meant as a compatibility barrier, and that these games will work on older hardware, too.

As it stands, the "Navi"-based Radeon RX 5000 series are "obsolete", just like some Turing cards from the GeForce GTX 16-series. At this time, the only shipping product which features the logo is NVIDIA's GeForce RTX 20-series and the TITAN RTX, as they support all the above features.

NVIDIA GeForce RTX GPUs to Support the DirectX 12 Ultimate API

NVIDIA graphics cards, starting from the current generation GeForce RTX "Turing" lineup, will support the upcoming DirectX 12 Ultimate API. Thanks to a slide obtained by our friends over at VideoCardz, we have some information about the upcoming iteration of the DirectX 12 API made by Microsoft. In the new API revision, called "DirectX 12 Ultimate", it looks like there are some enhancements made to the standard DirectX 12 API. From the leaked slide we can see the improvements coming in the form of a few additions.

The GeForce RTX lineup will support the updated version of API with features such as ray tracing, variable-rate shading, mesh shader, and sampler feedback. While we do not know why Microsoft decided to call this the "Ultimate" version, it is possibly used to convey clearer information about which features are supported by the hardware. In the leaked slide there is a mention of consoles as well, so it is coming to that platform as well.

TechPowerUp GPU-Z 2.30.0 Released

TechPowerUp today released the latest version of GPU-Z, the popular graphics subsystem information and diagnostic utility. Version 2.30.0 introduces several new feature- and stability updates, and adds support for new GPUs. To begin with, support is added for AMD Radeon RX 590 GME, Radeon Pro W5500, Pro V7350x2, FirePro 2260, and Instinct MI25 MxGPU; Intel UHD (Core i5-10210Y), and a rare GeForce GTS 450 Rev 2. TechPowerUp GPU-Z 2.30.0 introduces support for reporting hardware-accelerated GPU scheduling in Windows 10 20H1 in the Advanced tab. The tab now also has the ability to show WDDM 2.7, Shader Model 6.6, DirectX Mesh Shaders, and DXR tier 1.1. A workaround for the DirectML detection on Windows 10 19041 built has been added. Graphics driver registry path is now displayed in the General section of the Advanced tab.

In the Sensors tab, the NVIDIA VDDC sensor has been renamed to "GPU voltage," and AMD's "GPU only power draw" sensor to "GPU chip-only power draw" to clarify that the sensor only measures the power draw of the GPU package and not the whole graphics card. AMD "Renoir" based processors and their iGPUs now show up as 7 nm. Windows Basic Display driver now no longer reports its status as WHQL or Beta. A crash during DirectX 12 detection has been fixed.

AMD RDNA2 Graphics Architecture Detailed, Offers +50% Perf-per-Watt over RDNA

With its 7 nm RDNA architecture that debuted in July 2019, AMD achieved a nearly 50% gain in performance/Watt over the previous "Vega" architecture. At its 2020 Financial Analyst Day event, AMD made a big disclosure: that its upcoming RDNA2 architecture will offer a similar 50% performance/Watt jump over RDNA. The new RDNA2 graphics architecture is expected to leverage 7 nm+ (7 nm EUV), which offers up to 18% transistor-density increase over 7 nm DUV, among other process-level improvements. AMD could tap into this to increase price-performance by serving up more compute units at existing price-points, running at higher clock speeds.

AMD has two key design goals with RDNA2 that helps it close the feature-set gap with NVIDIA: real-time ray-tracing, and variable-rate shading, both of which have been standardized by Microsoft under DirectX 12 DXR and VRS APIs. AMD announced that RDNA2 will feature dedicated ray-tracing hardware on die. On the software side, the hardware will leverage industry-standard DXR 1.1 API. The company is supplying RDNA2 to next-generation game console manufacturers such as Sony and Microsoft, so it's highly likely that AMD's approach to standardized ray-tracing will have more takers than NVIDIA's RTX ecosystem that tops up DXR feature-sets with its own RTX feature-set.

Ray Tracing and Variable-Rate Shading Design Goals for AMD RDNA2

Hardware-accelerated ray tracing and variable-rate shading will be the design focal points for AMD's next-generation RDNA2 graphics architecture. Microsoft's reveal of its Xbox Series X console attributed both features to AMD's "next generation RDNA" architecture (which logically happens to be RDNA2). The Xbox Series X uses a semi-custom SoC that features CPU cores based on the "Zen 2" microarchitecture and a GPU based on RDNA2. It's highly likely that the SoC could be fabricated on TSMC's 7 nm EUV node, as the RDNA2 graphics architecture is optimized for that. This would mean an optical shrink of "Zen 2" to 7 nm EUV. Besides the SoC that powers Xbox Series X, AMD is expected to leverage 7 nm EUV for its RDNA2 discrete GPUs and CPU chiplets based on its "Zen 3" microarchitecture in 2020.

Variable-rate shading (VRS) is an API-level feature that lets GPUs conserve resources by shading certain areas of a scene at a lower rate than the other, without perceptible difference to the viewer. Microsoft developed two tiers of VRS for its DirectX 12 API, tier-1 is currently supported by NVIDIA "Turing" and Intel Gen11 architectures, while tier-2 is supported by "Turing." The current RDNA architecture doesn't support either tiers. Hardware-accelerated ray-tracing is the cornerstone of NVIDIA's "Turing" RTX 20-series graphics cards, and AMD is catching up to it. Microsoft already standardized it on the software-side with the DXR (DirectX Raytracing) API. A combination of VRS and dynamic render-resolution will be crucial for next-gen consoles to achieve playability at 4K, and to even boast of being 8K-capable.

UL Benchmarks Outs 3DMark Feature Test for Variable-Rate Shading Tier-2

UL Benchmarks today announced an update to 3DMark, with the expansion of the Variable-Rate Shading (VRS) feature-test with support for VRS Tier-2. A component of DirectX 12, VRS Tier 1 is supported by NVIDIA "Turing" and Intel Gen11 graphics architectures (Ice Lake's iGPU). VRS Tier-2 is currently supported only by NVIDIA "Turing" GPUs. VRS Tier-2 adds a few performance enhancements such as lower levels of shading for areas of the scene with low contrast to their surroundings (think areas under shadow), yielding performance gains. The 3DMark VRS test runs in two passes, pass-1 runs with VRS-off to provide a point of reference; and pass-2 with VRS-on, to test performance gained. The 3DMark update with VRS Tier-2 test will apply for the Advanced and Professional editions.
