Just for example. Use translator, but not from Swedish, it's clear that "Sweden" and "AMD" causes bugs in the same sentence.

 

Here there is only a guy that is using strawman, and that's you. Amd shop is Euro based, so if people is being able to buy it at MRSP in Italy it was possible in Sweden too. And I already reported you, it's the third time you accuse me of astroturfing when you are trolling since the first post.

 

And just to finish, this is the price situation for Ampere in Italy, TODAY

all i can say is i had an opertunity to buy the 6800 non xt on amazon for about 15 -20 minutes after launch it was in my cart too but i decided not too.

 

I'm rather confused here... For Navi21, are you saying there are 4 Rasterisers (Scan Converters), and 1 Rasteriser per Shader Engine?

Navi21 rasterises 4 triangles per cycle?

Each Rasteriser converts 1 triangle upto 32 fragments per cycle?

Is triangle coverage variable and what ranges - 4 to 32 fragments?

Four Shader Engines in Navi21 produce 128 fragments per cycle? And this matches 128 ROPs?

 

Thank you for the Information. So we can say now that Primitive shaders now working on RDNA2? Yikeeess! And thats why he sees a 80% improvment of polygon output between RDNA1 and RDNA2?

 

*Look at his Vega with disappointment*

 

Mesh shaders support was announced officially already on 28th or October, at the RX6000 series presentation

PixMark Julia FP32 (higher the better)


GiMark test (geometry instancing) (higher the better)

Tessellation Benchmark (higher the better)

3DMark DXR, Ray Tracing (higher the better)

3DMark VRS T2 (higher the better)

This is not mesh shader!? Like i anderstood he draw fthe polygons like before. Mesh Shader need Api Support?

 

That vrs result is interesting. Not many games support it yet. Could be important this gen.

 

yah mesh shaders use a new API in dx12 ultimate.

 

I believe the review mentioned they needed to verify the result.

 

4 triangles per clock at up to 128 pixels/clock. A triangle can touch a single pixel or up to 32 and theoretically maintain peak geometry rate. For comparison I think the RTX 3080 is 6 prims/clock and up to 96 pixels/clock.

 

Anyone else impatiently awaiting the 6900XT? Considering the FPS a 6800XT gets I can only hope a 6900XT can do 4k144 in GTA V. (and that the Sapphire 6900XT ToXic won't be €2000 lol)

 

Looks like that's just showing memory correction being engaged, too aggressive a memory overclock.

 

Raytracing is just another gimmick that gives us shinier reflections, prettier shadows and ambient occlussion while making the performance tank intolerably. That's about all the consoles can handle. Wake me up again when we see hardware that can render fully pathtraced scenes a'la Quake 2 RTX on modern titles.

 

Will definitely need to see how well RT works for games that aren't designed for RTX first work. On paper, there should still be enough RT performance on these cards to match the 2080ti but they lose more performance with RT enabled than the Nvidia 2000 series, maybe this will improve.

These cards do seem to do better on newer games than older games probably from being able to use dx ultimate features like VRS. Will probably age pretty well disregarding RT. 16GB of VRAM also is a nice bonus for longevity.

Really looking forward to the Navi 22 cards.
