NVIDIA RTX 3080 Ti and GA102 "Ampere" Specs, Other Juicy Bits Revealed

PC hardware focused YouTube channel Moore's Law is Dead published a juicy tech-spec reveal of NVIDIA's next-generation "Ampere" based flagship consumer graphics card, the GeForce RTX 3080 Ti, citing correspondence with sources within NVIDIA. The report talks of big changes to NVIDIA's Founders Edition (reference) board design, as well as what's on the silicon. To begin with, the RTX 3080 Ti reference-design card features a triple-fan cooling solution unlike the RTX 20-series. This cooler is reportedly quieter than the RTX 2080 Ti FE cooling solution. The card pulls power from a pair of 8-pin PCIe power connectors. Display outputs include three DP, and one each of HDMI and VirtualLink USB-C. The source confirms that "Ampere" will implement PCI-Express gen 4.0 x16 host interface.

With "Ampere," NVIDIA is developing three tiers of high-end GPUs, with the "GA102" leading the pack and succeeding the "TU102," the "GA104" holding the upper-performance segment and succeeding today's "TU104," but a new silicon between the two, codenamed "GA103," with no predecessor from the current-generation. The "GA102" reportedly features 5,376 "Ampere" CUDA cores (up to 10% higher IPC than "Turing"). The silicon also taps into the rumored 7 nm-class silicon fabrication node to dial up GPU clock speeds well above 2.20 GHz even for the "GA102." Smaller chips in the series can boost beyond 2.50 GHz, according to the report. Even with the "GA102" being slightly cut-down for the RTX 3080 Ti, the silicon could end up with FP32 compute performance in excess of 21 TFLOPs. The card uses faster 18 Gbps GDDR6 memory, ending up with 863 GB/s of memory bandwidth that's 40% higher than that of the RTX 2080 Ti (if the memory bus width ends up 384-bit). Below are screengrabs from the Moore's Law is Dead video presentation, and not NVIDIA slides.
As for performance, the "GA102" based prototype is allegedly clocking 40 percent higher performance than the RTX 2080 Ti at 4K UHD resolution in poorly optimized games, 50% higher performance on optimized games, and up to 70 percent performance in the "best case scenario" (a game that's been optimized for the "Ampere" architecture). We know from older leaks that by increasing the number of streaming multiprocessors, NVIDIA is doubling the CUDA core : RT core ratio compared to Turing, resulting in more RT cores per tier; and increased ray-tracing performance.

Each "Ampere" RT core is able to process 4x more intersections per unit clock-speed than "Turing." The tensor core count is also reportedly going to see an increase. The focus on ray-tracing and AI performance increase could give game developers the freedom to cram in more RTX effects per title, letting users disable what they want on older "Turing" cards. Performance limitations on "Turing" made developers choose from the RTX feature-set on what to implement. With "Ampere," NVIDIA could introduce DLSS 3.0, an updated image quality and performance enhancement. NVIDIA could resurrect a hybrid memory technology similar to AMD's HBCC, called NVCache, which spreads video memory across the video memory, the system memory, and flash-based storage.
Lastly, there's more clarity as to what silicon fabrication process NVIDIA could use. Apparently, NVIDIA will spread its product stack between two kinds of 7 nm-class nodes. The higher-end ASICs, such as the "GA102" and "GA103," could be built on 7 nm EUV nodes such as the TSMC N7+; while the smaller ASICs could be built on conventional DUV-based 7 nm-class nodes such as the N7P or even N7.

Don't pull your wallets out just yet. The launch schedule points to May 2020 (GTC) being focused on HPC parts based on "Ampere," such as the Tesla A100 and DGX A100 system.

In September 2020, NVIDIA will hold a separate event specifically to launch the next-generation GeForce, very close to "Cyberpunk 2077" release.

Thinking of 3070 for my main system and if they can get 1660 super or ti level performance with 1650 successor with no power cable would buy that as well for 1080p mini system but they will probably launch those much later dates.

I don`t understand what`s all this fuss about new videocards is unless you are filthy rich. There are plenty of used/mined cards out there after the mining burst that keep us going for the next 3 years. Just get a used GTX 1070 for 170-190$(1 year ago i got an asus rog strix rgb for 185$-in europe) and you can play whatever for the next 3 years , or rx 580 8 gb for 90$ is good enouf for most games. For me this next generation means nothing. Wake me up when we get 2080ti class performance at 250$ in 3-5 years time and maby i will be tempted to upgrade.

Sleep tight, sweet prince.

NV making upscaling mandatory...

LoL

Though I always thought the 2000 series was a beta test for actual RT hardware.

So I wonder if NV is feeling the heat of a challenge from AMD. This should be an exciting time.

Let's hope the 2080 Ti doesn't reach two years old before the challenge turns up.

RecusMoore's Law is Dead is AdoredTV's brother in lie. Don't believe their lies.
You can't expect leaks about pre-production silicon to be 100% representative of the end product. AdoredTV got a ton of stuff right in his Zen 2 leaks, like the fact that there would be a separate io die, and 16 cores on am4 using 2 x 8 core chiplets.

And there is always a possibility for "roadmap subject to change". AMD decided that there wasn't a need to be even more aggressive.

You play on 1080p don't you?
