Question for people that understand tech.

These upscale techniques that they use, if an image is upscaled from, say, 1080 to 4k, if the original image was 30fps, does that stay when converted or can that be changed to 60fps?

On PS systems it's been that if upscaled, fps could raised be raised as well as long as the game was "uncapped" in framerate

That stays unless you have the CPU overhead to handle it.

thank you

Yes RDNA 3 with rumor being it has custom RDNA4 features.

RDNA4 with RDNA2 design to be exact.

Also damn, already 1am. Hope we see more PCMR meltdown when I wake up.

Rumors I've seen are RDNA3 with RDNA4 features.

Kepler is right. RDNA3 on Navi 3x is different from Navi 2x, it uses 8WGP per Shader Engine:

Except for the Navi 32, which has 3 shader engines. If you consider 8WGP to be the standard, then it would have 48CU, or would require a completely new shader engine to reach the fabled 64. The 7800xts was to be a cutdown Navi 31, not a souped up Navi 32.

You have the 7700xt which is a cut down Navi 32, and the 7800xt which is the full chipset.

AMD Radeon RX 7800 XT Review

With the Radeon RX 7800 XT, AMD is going after the GeForce RTX 4070. Our review confirms that AMD has achieved performance parity in rasterization and is pretty close in ray tracing, at a much better price point, and they are giving you 16 GB VRAM, instead of just 12 GB.

Also, not all Navi 2x cards have 10WGP per shader engine.

As for the clockspeeds, I do believe those 2180MHz are base clocks like 2GHz were for the PS5, but until the first batches of production units are out there with final cooling solutions etc.

I agree with this.

Kepler is right. RDNA3 on Navi 3x is different from Navi 2x, it uses 8WGP per Shader Engine:

They're claiming the PS5 Pro's GPU is 2/3rds the size of a Navi 31.

I've never seen an official block diagram for Navi 32 so I don't know if it has in fact 64 CUs total and the 7800XT already does have 2 WGPs disabled for redundancy, leaving the solution open for a slightly faster 7800XTX down the road (if/when they get faster spins for the N32 chip).


As for the clockspeeds, I do believe those 2180MHz are base clocks like 2GHz were for the PS5, but until the first batches of production units are out there with final cooling solutions etc. Sony can't compromise on how high they can boost the clocks on average.
I'd say they're confident they can achieve at least those 2450MHz with which they can reach 300 TOPs. Though if N33 on N6 is any indication, we could be looking at closer to 2600MHz on average (which leads the GPU to almost 40 TFLOPs).

did you just tell me that PS5 PRO is more powerful than it shown?

30fps means 30 images (frames) per second… the upscale techs do it to each image/frame so it won’t increase the images/frames to 60 per second.

You will still have 30 images/frames per second but now they frames/images will be uoscalled to 4k.

 

[anonpuffs]

Off topic but is today Circana/NPDs?

Tomorrow i believe

There is no upscale fps.

When you cap the framerate to 30fps it means the GPU is rendering over the target like 35, 37, 40, 48, etc and so it is caped to only output 30 and discard the rest.


When you uncap it the discard is cancelled and the output start to be what is being rendered: 35, 37, 40, 48, etc.

Upscaling refer to each frame… and not how many frames is being rendered… in fact upscaling has a overhead so doing upscaling will probably make the GPU render a few lower frames per second than if not upscaling… depend of course how costly is the upscaling algorithm to the GPU.

Plus reconstruction techs like DLSS are way more costly to GPU than upscaling… needs around 30% more GPU power… for example a 1080p target running at average 60fps will probably drop to around 40fps when using DSLL 1080p to 4k (Performance profile).

Of course the cost for DLSS 1080p to 4k is still lower than native 4k… if we take the 30% then it will be around 65% less expensive to the GPU than native 4k.

Let me guess, "Its a good upgrade but wholly unnecessary. We look forward to what xbox is doing next though."

Pretty much, they avoid comparisons, except to imply that Sony somehow went in a more like series X path (even tho it has less CUs per TF)... but they are very much downplaying it with their analysis.

Also, they are still very "concerned" about the power envelope and those varying clock speeds.

These people are repeating the 2020 talking points.

 

[Darth Vader]

You guys are setting yourselves up for disappointment. I will keep up with my bet, which could be incorrect. Full specs:

• Zen2 CPU @ 3.85GHz
• Navi 32 based GPU with 60CU (6 disabled for yields) at 2.42GHz
• 16GB GDDR6 @ 18GBps

They can technically go with either 56CU which will impact yields, or they have a custom design that allows for 4 shader engines with 8WGP each (meaning the card is not Navi 31 or 32 based).

 

[anonpuffs]

We are all very aware of this as well, but what nobody else seems to be aware of is that a 35 teraflop RDNA 3 GPU performs to the same degree that a 16 teraflop RDNA 2 GPU does.

That's not quite true. For example, the 7800xt has 18.5 "rdna2" tflops and yet performs almost the same as the 6800xt which has over 20. There were architectural improvements so I expect performance on the level of an 18-19tf rdna2 card in raw performance.

You took my comment out of context. There should have been a comma after upscaled seperating the two. Wth says upscaled fps?

 

[Alabtrosmyster]

That prick Alex bagaga is there, not even worth watching

No worries, the others are in on the same game.

I could not finish it with all their "concerns" and "analysis".

This is not supposed to be a next-gen console.

I was just joking. Don't you know the meme?

Did you just tell me that i have a chance?( After saying it is 0.000001%)

I am looking at stats, nothing more. More than anything, i am waiting results, how it will translate into performance.
I think, many people have learned already from PS5 stats about tech.

That is one of the biggest issue with AMD marketing…

7800XT should perform on pair with 6900XT not 6800XT.
6800XT performance level should be 7700.

When you release a new generation of cards you have to increase the performance in the same range level… not continue the same.

See nVidia.

2080… 1080TI
2070… 1080
3080… 2080TT
3070… 2080

7800XT performing similar to 6800XT is basically killing your own product… because 7800XT is more expensive and don’t delivery more.

AMD has done fake new products for a very long time now.

The Radeon 480 and 580 were pretty much on par with each others and even back then it was talked about as if this was the usual way.

Honestly, I just want to get games, and that has been lacking.
