AMD Navi 23 ‘NVIDIA Killer’ GPU Rumored to Support Hardware Ray Tracing, Coming Next Year

[Howling]

RDNA1 is vastly better than GCN, its not going to be anything like that uplift, AMD said 10%+ higher IPC, we know RDNA2 clocks about 350Mhz higher that RDNA1, about ~20%, so take that and add the 10 IPC (+30% Total) and then you have a formula for an RDNA1 vs RDNA2 GPU comparison, a 2560 Shader RDNA2 GPU is 30% more GPU than a 2560 Shader RDNA1 GPU. Beyond that you add the shaders in whatever the RUMOURS are and take some performance off for scaling, with that you can get a good idea what a 2560 Shader RDNA2 GPU would look like, or a 3840 Shader RDNA2 or a 5120 Shader RDNA2 GPU.

I don't know if you're just rounding your percentages... but your maths is off again 100% + 10% = 110% .. +20% = 132% because the 20% higher clocks is applied to the 110% performance at the same clock. Just nit picking I know, but I picked your maths up the other day too so I thought I'd do it again >

 

[humbug]

I'm rounding ^^^ at least its down not up
------------

Maybe some people get confused by these huge uplifts because AMD's current high-end GPU, the 5700XT is only = to a 2070 Super, not a particularly fast card, how can one step up in generation be that much faster? two times as fast?

The 5700XT is not a high-end GPU, not even by AMD's current standards, its an RX 580 replacement, its even the same 250mm2 size with only about 10% more shaders, yet its twice as fast, that's the difference between GCN and RDNA1.

AMD made a small mid range GPU, they didn't bother to make a larger one this generation, had they, perhaps 3840 shader version the 2080TI would not have been alone at the top of the charts.

IF AMD do make larger version this time round they will be punching higher up the charts, how high depends on how large AMD are willing to go, that is the real question.

So are we shovelling coal into the hype train now?

 

[LePhuronn]

You are right to point that out. Unfortunately, we don't know how well RDNA gen 1 compares with RDNA gen 2. No one from AMD, Microsoft, Sony or any game developers (that I'm aware of) have given us any idea of the performance benefit.

We only have limited information about the performance benefit from GCN to RDNA 2.

Therefore, comparing RDNA 2 to a Radeon VII is still a valid comparison.

But we do know RDNA 1's performance, so just use the 5700XT. You're overcomplicating things using Radeon VII comparing Radeon it to a semi-custom GCN found in the XBone without any actual comparative numbers. How much stronger is Radeon VII over the XBone?

So no, Radeon VII is not a valid comparison, it's a repurposed compute card using a shrunk and modified Vega arch which isn't even in the XBone.

If RDNA2 is anything close to a 3080 i was cancel my pre order and swipe one of these pending on availability. I need a card, sick of looking at a wee 1060 3gb lol

No we've run out of coal stocks on the Nvidia one. This is more like wood for the Hype Steam Boat !

Sounds like you got put in your Plaice.

 

[humbug]

Aww..... carp! Please stop.

 

[EastCoastHandle]

After their awful launch I think nv have lost a good chunk of consumer confidence & they will only lose more when they release their more powerful cards.. as confirmed here:

Feels like amd have an open goal.. really hope they don't miss

hahaha
More like a "self goal" to me.
It will be hard to ignore that "Nvidia did it again..."
If the S variants cost withing 10% it would be like icing on a cake.

No let's keep going for the halibut.

it's a repurposed compute card.

The fact that the Radeon VII was created alongside some 7nm compute capable cards is irrelevent, the Radeon VII itself was not designed for Compute, it's a gaming GPU.

If we used Navi in the calculations instead of a GCN Radeon VII, you be likely to get +50% performance improvement if there is a 50% increase in CUs (to 60) and a 50% increase in GPU clocks, vs a 5700 XT. That would require a rather massive GPU clock of ~2857mhz (1905mhz + 50%).

Comparing the 5700 and 5700 XT, a CU and clock increase (+11.1% CUs, +10.4% GPU clocks) was needed to gain a proporsional performance increase in the 3D Mark GPU benchmark (based on the percentage increase in Compute Units from the 5700 to 5700 XT).

Using similar logic, you be likely to get +100% performance improvement if there is a 100% increase in CUs (to 80) and a 100% increase in GPU clocks, vs a 5700 XT. That would require a GPU clock of ~3810mhz!

Comparing a 60 CU GCN card to RDNA 2 is actually more favourable in perf terms imo.

Comparing RDNA 2 to Radeon 7 is a bit like comparing RDNA 2 to Fermi. They are so different there is no point.

The vega7 is a rejected MI50 die, repurposed as a gaming card

 

[g67575]

I guess the Radeon VII must be terrible then, since you put it like that

Far from it. In the right workloads it is an absolute monster. As a gaming card it's fairly meh but as a general purpose compute & gaming card... its a beastie.

 

[DDH]

I really hope AMD or their partners are ready to get slammed on launch day, and have appropriate steps in place to mitigate botters and scalpers.

3080 launch, ps5 pre orders and yesterday series X pre orders have all been hit hard. I hope they limit cards purchased to 2 per household, with captcha and maybe limit purchasing on the same CC or something

 

[g67575]

The Radeon VII is best performing GCN GPU, that's why I picked it to compare with RDNA 2, rather than the somewhat somewhat 'meh' Vega 64.

no Instinct MI60 is the best performing GCN as it has all the 4096 shaders on the 4096 bit bus rather than the 3840 shaders the 7 has (7 is an mi50). You just cant buy one and if you do it has no display outputs.
