AMD RDNA3 unveiling event

They haven't but the assumption or rumour is they will.

Current 7800XT rumour. https://www.techpowerup.com/gpu-specs/radeon-rx-7800-xt.c3839

It says total die size 350mm, but that's including 4 MCD's at 37mm each, so the GPD is 200mm, its very small, to put that in to perspective an RX 6600XT which is a full size Navi 23 is 237mm.

3840 Shaders, that's only 62.5% of the 7900XTX, that's quite a drop, especially when you consider the 7900XTX is only 35% faster than the 6950XT on average, 51% faster than the 6800XT, its a 60% difference in shaders 7800XT vs 7900XTX.

This is another reason people think something has gone wrong with driver development, AMD didn't just lie on the charts hoping to fool us all, they thought it would end up at between 50% to 70% faster than the 6950XT, RDNA2 performance slides were also published while AMD still had the drivers in development.

Just 2-3 months ago people were getting excited at the proposition of 6950xt performance in the 7700xt and now it looks like 6900xt performance in the 7800xt

Matt works for AMD, he seems to always get performance others can't. Also based on the 3D mark benches Matt seems to be able to run his cards very cold - probably sticks an air conditioner on the case or some other form of phase change cooling

Despite having the highest 3DMark score for Nvidia? I think he just knows how to get performance out of any GPU.

I bet @LtMatt gets way more than 8% out of it with 500W

Remember, this is 8% over a stock Nitro, not 8% over a stock MBA. It's not bad though for a quick tune tbh. The higher power limit of the stock Nitro will always give a higher score and therefore don't expect 25% gains as these cards won't always be power limited, especially below 2160P. These reviewers just push the sliders up and test, that's it.

You mean pushing a few sliders and maxing fan speed? it aint rocket science, you are limited by silicon quality not your ability to OC, unless we are talking exotic cooling world record attempts.

Yes, you just need to know what you are doing when it comes to tuning hardware and test your settings. Sometimes even a 2-4Mhz change in memory frequency adjustment can bring nice gains in performance improvement.

Most people don't have the patience or knowledge to properly tune. They get critical when they cannot achieve these kind of performance increases and start trying to find false reasons for how performance can be extracted from hardware. None of my XTX or 4090 scores were using anything other than air cooling, no water/phase/air conditioning either. Not at these energy prices. Only used Liquid Metal on the 4090 and the MBA card. The TUF OC is still running the stock paste.
See @Grim5 and @RavenXXX2 for perfect examples of this. I take it as a compliment, means you are doing something well. :)

I beat Grim's 4090 Port Royal score with my 4090 too by over 11%. ;)

Update on 110c issue, AMD is now paying out refunds for those who bought direct from the AMD store, they have no 7900xtx in stock for RMAs so are just refunding people.

Matthew unfortunately its only "8%". We have had two years of only "10%" which mythically grew to 20% near the end of the Ampere gen. :cry:

The 7900XTX Tier 1 cards have not appeared yet, the 4080 has its first Tier 1 card appear in the guise of the 4080 Strix OC and the out-of-the-box increase over reference is approx. 2% and 7% if you run the 4080 Strix power-limiter at approx. 550watts.

What Matt is running is a Tier 2 and Tier 3 7900XTX board(s) against people running Tier 1 4080 and 4090 boards. We won't have a fair fight until the Tier 1 7900XTX boards break cover at CES.

OK, I get that people would like to have more for less, and we’ve had decades of each generation giving more for less, but that doesn’t hold for many products right now. We’re seeing it with cars, premium hifi (maybe all - I’ve not looked), groceries, etc.

Added to that, when comparing these, most (if not all) have more VRAM.

So yes, I’d really like to see the same equation as in previous years, but is it realistic to expect it? Only if you’ve been living in a bubble for the past 2 years …

And yet prices also went down, including fuel and gas.

That's the median price in stores, not some "lying" average. 1 euro = 5lei

I struggle to see that being the case as the announcement wasn't that far before release, surely they would known the performance of the cards at that point.

The 7800XT won't be compelling at the same price point as the 6800XT, the uplift won't be there as there isn't much room for it to be more than 15-20% faster judging by the 7900 series. Had the XT come in at that price then it would have been ok, not great, but ok.
 
Someone correct me if I am wrong but I'm pretty sure the reason amds pr slides had very different numbers was because for their rdna 3 system they were using 7950x with sutpidly fast DDR 5 ram where as the 6950xt system as using a 5950x with ddr4? If true.... then amd were 100% intentionally misleading their fanbase/customers......

What’s the difference with a Tier 1 card. Is it just cherry picked chips or something?

I think he was just trained by AMD, he knows his stuff, seems to get every last drop out of anything he touches.
