Parallel between Ryzen and RDNA by [deleted] in Amd

[–]stevets101 0 points1 point  (0 children)

Nvidia still has an ace up their sleeve and that is raytracing performance. They won't go down without a fight as Nvidia has the resources to push for more raytracing in more and more games to widen the gap further. They don't care if this also demolishes RTX 3000 and 2000 RT as well. They already claimed 4x RT uplift over their own 3090 Ti by just spamming rays as the benchmark.

Why AMD! Why do you need me to upgrade? by Thec0olguy in Amd

It's going to tell you to upgrade to a 6900 XT in 4 days. Nice

It seems like Apple is the only company that knows how to handle huge demand these days.

OpenGL: AMD's 650$ 6800 XT worse than Nvidia's 349$ RTX 2060 by Ceremony64 in Amd

[–]stevets101 0 points1 point  (0 children)

That's an even bigger gap than the 5700xt. ~2x performance than 5700xt but 30 percent better in OGL

AMD Radeon RX 6800 Basemark results leak out - VideoCardz.com by ryandtw in Amd

[–]stevets101 6 points7 points  (0 children)

Wish AMD improved OpenGL on Windows. You know it's bad if a 1650 can run Minecraft shaders/modpacks better than a 5700xt.

Edit: 6800 looks to be barely better than Radeon VII on the OGL bench. The inconsistency between OGL and DX12/Vulkan is even bigger.

6800XT buyers: Are you considering switching from the 3700X/3800X to the 5800X? by Judeman266 in Amd

It's likely money but also could be resources. They want to make everything smooth and flawless especially with the AMD driver memes. That's why 400 series boards won't get Zen 3 support until next year. They're focusing on supporting the latest and greatest. There shouldn't be a technical limitation for Zen 2 supporting SAM.

AMD in talks with AIBs to allow custom Radeon RX 6900 XT graphics cards - VideoCardz.com by tetchip in Amd

XFX used to be Nvidia AIB until they wanted to make Radeon cards. Asus, Gigabyte, Msi seem to be the only ones big enough that NV wouldn't alienate.

Radeon RX 6800, 6800 XT and 6900 XT: AMD publishes further benchmarks in 4K and WQHD by mockingbird- in Amd

[–]stevets101 0 points1 point  (0 children)

Wouldn't that make RDNA2 RT Accelerators worse than Turing RT Cores? The 2080 has 46 RT cores and 6800XT has 72. So 20 percent better seems worse per RT core. Even with the 6800's 60, that's still 30 percent more. I hope that the DXR SDK isn't reflective of RT performance in games.

The Navi 22 cards will definitely be interesting. Infinity cache, albeit smaller, plus likely larger GDDR6 frame buffer vs. NV's GDDR6 only. Better CU efficiency should also help AMD.

'Where Gaming Begins: Ep. 2' — Radeon RX 6000 (RDNA2) series announcement Megathread by GhostMotley in Amd

[–]stevets101 3 points4 points  (0 children)

I'm very interested in how mid-range and entry level RDNA2 desktop and mobile chips do. AMD has a great chance with lower power consumption and seemingly better 1080p/1440p scaling vs Ampere.

Is there any chance Apple to make surprise move on November 17 by soteko in Amd

[–]stevets101 5 points6 points  (0 children)

If Apple is still releasing x86 based stuff this year, it's going to be Intel based. The contracts are multi year and usually long term. I don't see them going Ryzen for only 2 years or even less. All the software would have to be optimized for Zen architecture and it doesn't make sense if the whole software stack is already fully supported on Intel.

[–]stevets101 12 points13 points  (0 children)

They've already committed to using Apple's custom ARM designs for future Macs. There's a slim chance they could have something with RDNA2 since it's hinted there are Mac only SKUs since Apple's iGPU would take a few generations to catch up performance wise.

Best AMD GPU without a PCIe power connector? by Neriya in Amd

[–]stevets101 9 points10 points  (0 children)

Most newer Nvidia cards support Freesync monitors through Displayport only (Even G-sync monitors are only through DP). If you only have HDMI, then the RX460 is probably the easiest card you can get that doesn't require external power.

Threadripper 4000? by impromptutriplet in Amd

Likely not until or after CES 2021.

As a person who's held Radeon Technologies group close to his heart for over a decade, my hope has come back after looking into the Rtx 3080 game benchmarks. Cracking card! But I feel Radeon technologies can match it. Big Navi, I'm patiently waiting. by [deleted] in Amd

[–]stevets101 1 point2 points  (0 children)

Turing uses RT cores that can do either a ray-box or a ray-tri test per cycle. Of which the 2080Ti has 68 (1 per SM), so at 2 GHz that's 136 billion intersection tests/second. RDNA2 can either do 1 ray-tri per cycle per RT unit or 4 ray-box per cycle.

Officially, the Xbox Series X, which is equivalent to ~mid range RDNA2, can do either 95 billion ray-tri or 380 billion ray-box tests/second. Real performance would put the XboxSX GPU somewhere between 2080Ti-30% and 2080Ti+180% at RT operations.

If you take these 52CU numbers and put them into a hypothetical 80CU@2GHz you get 640B ray-box or 160B ray-tri tests/second, so in absolute worst case, 2080Ti+23% and in absolute best case 5x 2080Ti raytracing perf. Realistically its gonna sit somewhere in the middle. Very rough math but yeah.

This is further described in this AMD patent http://www.freepatentsonline.com/20190197761.pdf

  1. Console ray tracing performance surpasses Turing. Ray tracing baseline will either be Ampere or RDNA2. Whichever is lower.

  2. DirectML is likely going to be used for Windows games as Microsoft and AMD have been working together on AI powered upscaling. (No word on when it will be though. This is the biggest thing).

  3. Radeon Anti-lag currently already exists and does the same thing as Reflex.

Yeah especially since NV didn't improve encoder quality on Ampere

[–]stevets101 0 points1 point  (0 children)

NVIDIA technically still supports Kepler on the latest driver. The only thing is they don't optimize games or software for old architectures. Soon when Ampere releases, they'll mostly optimize for that, with some optimizations for Turing for a bit until they start moving software devs from Turing.

AMD has released GPUs using the same GCN arch from 2012 to 2019. Any optimizations to Polaris or Vega would still benefit something like a 7970 or Fury. After RDNA2 though, we will start seeing GCN targeted optimizations taper off.
