The "Rocket Lake-S" microarchitecture by Intel sees the company back-port its next-generation "Willow Cove" CPU core to the existing 14 nm++ silicon fabrication process in the form of an 8-core die with a Gen12 Xe iGPU. An engineering sample of one such processor made it to the Futuremark database. Clocked at 3.20 GHz with 4.30 GHz boost frequency, the "Rocket Lake-S" ES was put through 3DMark "Fire Strike" and "Time Spy," with its iGPU in play, instead of a discrete graphics card.

In "Fire Strike," the "Rocket Lake-S" ES scores 18898 points in the physics test, 1895 points in the graphics tests, and an overall score of 1746 points. With "Time Spy," the overall score is 605, with a CPU score of 4963 points, and graphics score of 524. The 11th generation Core "Rocket Lake-S" processor is expected to be compatible with existing Intel 400-series chipset motherboards, and feature a PCI-Express gen 4.0 root complex. Several 400-series chipset motherboards have PCIe gen 4.0 preparation for exactly this. The increased IPC from the "Willow Cove" cores is expected to make the 8-core "Rocket Lake-S" a powerful option for gaming and productivity tasks that don't scale across too many cores.

We have been hearing a lot about Intel's Rocket Lake lineup of processors. They are supposed to be a backport of Willow Cove 10 nm core, adapted to work on a 14 nm process for better yielding. Meant to launch sometime around late 2020 or the beginning of 2021, Rocket Lake is designed to work on the now existing LGA1200 socket motherboards, which were launched just a few days ago along with Intel Comet Lake CPUs. Rocket Lake is there to supply the desktop segment and satisfy user demand, in light of lacking 10 nm offers for desktop users. The 10 nm node is going to present only on mobile/laptop and server solutions before it comes to the desktop.

In the latest report on 3D Mark, the hardware leaker TUM APISAK has found a Rocket Lake CPU running the benchmark and we get to see first specifications of the Rocket Lake-S platform. The benchmark ran on 6 core model with 12 threads, that had a base clock of 3,5 GHz. The CPU managed to boost up to 4,09 GHz, however, we are sure that these are not final clocks and the actual product should have even higher frequencies. Paired with Gen12 Xe graphics, the Rocket Lake platform could offer a very nice alternative to AMD offerings if the backport of Willow Cove goes well. Even though it is still using a 14 nm node, performance would be good. The only things that would be sacrificed (from backporting) are die space and efficiency/heat.

Intel Xe graphics architecture makes its commercial debut as an iGPU solution in the company's upcoming "Tiger Lake" mobile processors. The iGPU can be configured along three tiers, with GT1 featuring 48 execution units (EUs), GT2 80 EUs, and GT3 leading the pack with 96 EUs, all within a 15 W envelope (for the total chip). There's a higher tier still of GT3 that comes with higher boost frequencies, tapping into the chip's overall increased 28 W TDP, but this variant of "Tiger Lake" could likely be an Apple-exclusive like its "Ice Lake" based predecessor.

NotebookCheck compiled a 3DMark FireStrike comparison between the various tiers of the Xe iGPU, and compared it to the Gen11 iGPU found with current-generation "Ice Lake-U" processors. The graph doesn't put out scores, but relative performance. Apparently, the 48 EU version of Gen12 Xe is a little over twice as fast as Gen11 GT1, and faster than even the 64 EU Gen11 GT2. The Gen12 GT2 with 80 EUs is around 1.7x faster than the Gen11 GT2 (64 EU). The 96 EU GT3 trim is over twice as fast, and its 28 W variant faster still. These performance give Gen12 a shot against AMD's Radeon Vega-based iGPU solution found in "Renoir." AMD has slimmed the number of CUs down to 8 (512 SP) with "Renoir," down from 11 CUs in the previous generation, compensating for it with higher GPU engine clocks.

Intel's ambitious Xe graphics architecture is expected to make its first commercial debut as an iGPU that's part of the company's 11th gen Core "Tiger Lake" mobile processors, but it already received a non-commercial distribution as a discrete GPU called the DG1, with Intel shipping it to its independent software vendor ecosystem partners to begin exploratory work on Xe. One such ISV paired the card with a Core i7-8700 processor, and put it through Geekbench. While the Geekbench device identification doesn't mention "DG1," we lean toward the possibility looking at its 96 EU configuration, and 1.50 GHz clock speed, and 3 GB memory.

The Geekbench run only covers OpenCL performance of the selected device: "Intel(R) Gen12 Desktop Graphics Controller." The total score is 55373 points, with 3.53 Gpixels/s in "Sorbel," 1.30 Gpixels/sec in Histogram Equalization, 16 GFLOPs in SFFT, 1.62 GPixels/s in Gaussian Blur, 4.51 Msubwindows/s in Face Detection, 2.88 Gpixels/s in RAW, 327.4 Mpixels/s in DoF, and 13656 FPS in Particle Physics. These scores roughly match the 11 CU Radeon Vega iGPU found in AMD "Picasso" Ryzen 5 3400G processors.

An Intel Gen12 Xe GPU, possibly a discrete- DG1 prototype, showed up on the SiSoft SANDRA online database. The GPU is detailed by SANDRA as having 768 unified shaders across 96 execution units (EUs), a 1.50 GHz GPU clock speed, 1 MB of on-die L2 cache, and 3 GB of dedicated video memory of an unknown type (likely GDDR6). This is probably a different chip from the DG1-SDV, which caps out at 900 MHz GPU clock, although its SIMD muscle is identical.

At a clock-speed of 1.50 GHz, the chip would feature an FP32 throughput of 2,303 GFLOPs (we know this from the DG1-SDV offering 1382 GFLOPs at 900 MHz). If the software-side optimization backs this hardware, the resulting product could end up with performance in the league of the 8 CU Radeon "Vega" solution found in the AMD "Renoir" APU, or the Radeon RX 560 discrete GPU, which are just about enough for PUBG at 1080p with medium settings.

Intel's first integrated graphics solution based on its ambitious new Xe graphics architecture, could match AMD's "Vega" architecture based iGPU solutions, such as the one found in its latest Ryzen 4000 series "Renoir" iGPUs, according to leaked 3DMark FireStrike numbers put out by @_rogame. Benchmark results of a prototype laptop based on Intel's "Tiger Lake-U" processor surfaced on the 3DMark database. This processor embeds Intel's Gen12 Xe iGPU solution, which is purported to offer significant performance gains over current Gen11 and Gen9.5 based iGPUs.

The prototype 2-core/4-thread "Tiger Lake-U" processor with Gen12 graphics yields a 3DMark FireStrike score of 2,196 points, with a graphics score of 2,467, and 6,488 points physics score. These scores are comparable to 8 CU Radeon Vega iGPU solutions. "Renoir" tops out at 8 CUs, but shores up performance to the 11 CU "Picasso" levels by other means. Besides tapping into the 7 nm process to increase engine clocks, improve the boosting algorithm, and modernizing the display- and multimedia engines; AMD's iGPU is largely based on the same 3-year old "Vega" architecture. Intel Gen12 Xe makes its debut with the "Tiger Lake" microarchitecture slated for 2021.

Intel's upcoming Rocket Lake-S desktop platform is expected to arrive sometime later this year, however, we didn't have any concrete details on what will it bring. Thanks to the exclusive information obtained by VideoCardz'es sources at Intel, there are some more details regarding the RKL-S platform. To start, the RKL-S platform is based on a 500-series chipset. This is an iteration of the upcoming 400-series chipset, and it features many platform improvements. The 500-series chipset based motherboards will supposedly have an LGA 1200 socket, which is an improvement in pin count compared to LGA 1151 socket found on 300 series chipset.

The main improvement is the CPU core itself, which is supposedly a 14 nm adaptation of Tiger Lake-U based on Willow Cove core. This design is representing a backport of IP to an older manufacturing node, which results in bigger die space due to larger node used. When it comes to the platform improvements, it will support the long-awaited PCIe 4.0 connection already present on competing platforms from AMD. It will enable much faster SSD speeds as there are already PCIe 4.0 NVMe devices that run at 7 GB/s speeds. With RKL-S, there will be 20 PCIe 4.0 lanes present, where four would go to the NVMe SSD and 16 would go to the PCIe slots from GPUs. Another interesting feature of the RKL-S is the addition of Xe graphics found on the CPU die, meant as iGPU. Supposedly based on Gen12 graphics, it will bring support for HDMI 2.0b and DisplayPort 1.4a connectors.

Intel's upcoming 400-series desktop chipset will lack support for PCI-Express gen 4.0. The motherboards will stick to gen 3.0 for both the main x16 PEG slots wired to the LGA1200 socket, and general purpose PCIe lanes from the PCH, according to a Tom's Hardware report. It was earlier expected that 400-series chipset motherboards will come with preparation for PCIe gen 4.0, so even if the upcoming 10th gen "Comet Lake" desktop processors lacked gen 4.0 root-complexes, the boards would be fully ready for the new bus standard in 11th gen "Rocket Lake" desktop processors.

10th gen "Comet Lake" desktop processors are built on 14 nm process, and implement Intel's current-gen CPU core design Intel has been implementing since 6th gen "Skylake." It's only with 11th gen "Rocket Lake" that the mainstream desktop platform could see a new CPU core design, with the company reportedly back-porting "Willow Cove" CPU cores to the 14 nm process. "Rocket Lake" is also expected to feature a small Gen12 iGPU with 32 execution units, and a new-gen uncore component that implements PCIe gen 4.0. PCIe gen 4.0 doubles bandwidth over gen 3.0, and while only a handful GPUs support it, the standard is made popular by a new generation of M.2 NVMe SSDs that are able to utilize the added bandwidth to push sequential transfer rates beyond M.2 PCIe 3.0 x4 limitations.

Intel's 11th generation Core "Rocket Lake-S" desktop processor will come in core-counts only up to 8, even as its predecessor, "Comet Lake-S," goes up to 10. Platform descriptors for Intel's next four microarchitectures surfaced on the web, detailing maximum values of their "S" (mainsteam desktop), "H" (mainstream notebook), "U" (ultrabook), and "Y" (low power portable) flavors. Both "Comet Lake-S" and "Rocket Lake-S" are 14 nm chips. "Comet Lake-S" comes with core counts of up to 10, a TDP of up to 125 Watts, Gen 9LP iGPU with 48 execution units, and native support for up to 128 GB of DDR4-2667.

The "Rocket Lake-S" silicon is interesting. Rumored to be yet another derivative of "Skylake," it features up to 8 CPU cores, the same 125 W maximum TDP, but swanky Gen12 iGPU with 32 execution units. The memory controller is also upgraded, which supports DDR4-2933 natively. There is no "Ice Lake-H" or "Ice Lake-S" in sight (no mainstream notebook or mainstream desktop implementations), ditto "Tiger Lake." For the foreseeable future, Intel will only make quad-core designs of the two 10 nm microarchitectures. "Rocket Lake-S" is slated for 2021 when, hopefully, we'll see Intel escape the 14 nm black hole.

In a shocking piece of news, Intel has reportedly scrapped plans to launch its 10 nm "Ice Lake" microarchitecture on the client desktop platform. The company will confine its 10 nm microarchitectures, "Ice Lake" and "Tiger Lake" to only the mobile platform, while the desktop platform will see derivatives of "Skylake" hold Intel's fort under the year 2022! Intel gambles that with HyperThreading enabled across the board and increased clock-speeds, it can restore competitiveness with AMD's 7 nm "Zen 2" Ryzen processors with its "Comet Lake" silicon that offers core-counts of up to 10.

"Comet Lake" will be succeeded in 2021 by the 14 nm "Rocket Lake" silicon, which somehow combines a Gen12 iGPU with "Skylake" derived CPU cores, and possibly increased core-counts and clock speeds over "Comet Lake." It's only 2022 that Intel will ship out a truly new microarchitecture on the desktop platform, with "Meteor Lake." This chip will be built on Intel's swanky 7 nm EUV silicon fabrication node, and possibly integrate CPU cores more advanced than even "Willow Cove," possibly "Golden Cove."

Intel's upcoming Gen12 iGPU solutions are being touted as sporting Intel's greatest architecture shift in their integrated graphics technologies in a decade. For one, each Execution unit will be freed of the additional workload of having to guarantee data coherency between register reads and writes - that work is being handed over to a reworked compiler, thus freeing up cycles that could be better spent processing triangles. But of course, there are easier ways to improve a GPU's performance without extensive reworks of their design (as AMD and NVIDIA have shown us time and again) - simply by increasing the number of execution units. And it seems Intel is ready to do just that with their Gen12 as well.

An unidentified Intel Gen12 iGPU was benchmarked in CompuBench, and the report includes interesting tidbits, such as the number of Execution Units - 96, a vast increase over Intel's most powerful iGPU to date, the Iris Pro P580, with its 72 EU - and far, far away from the consumer market's UHD 630 and its 24 EUs. The Gen12 iGPU that was benchmarked increases the EU count by 33% compared to Intel's top performing iGPU - add to that performance increases through the "extensive architecture rework", and we could be looking at an Intel iGPU part that achieves some 40% (speculative) better performance than their current best performer. The part was clocked at 1.1 GHz - and the Iris Pro P580 also clocked to that maximum clock under the best Boost conditions. Let's see what next-gen Intel has in store for us, shall we?
