AMD Radeon RX 7000 RDNA3 To Launch Early December
AMD's next-generation Radeon RX 7000-series graphics cards based on the RDNA3 graphics architecture, are expected to launch in early-December 2022, according to greymon55, a reliable source with AMD leaks. The cards will be unveiled at a media event to be held on November 3, 2022, with market availability following a month after (between 1st to 5th December). The company is expected to take a top-down product-stack release cycle similar to that of NVIDIA, with the release of two of its top SKUs, the Radeon RX 7900 XTX and the RX 7900 XT. Both these cards are based on the 5 nm Navi 31 MCM GPU. This will be AMD's first client-graphics MCM GPU with more than one logic die. The company has a decade of experience with MCMs, but past generations have been one logic die surrounded with on-package HBM. Navi 31 has on-package logic chiplets, but discrete GDDR6 memory, like most other GPUs in the market today. It's rumored that the company is targeting a 100% performance uplift over the previous-generation, which means team-red is on the prowl to compete with NVIDIA's fastest SKUs, including the RTX 4090 and upcoming RTX 4080.

Are they really aiming to double the performance? wonder if they can pull this off.
- assess outright performance
- assess RT performance / impact
- the pricing.
- see if it affects pricing of other products
- See how big and power hungry they are
- see if FSR evolves and is accelerated by RDNA3
- get a sense of stock levels and availability
Lots to look forward to, even if you don't want to buy one.On the bright side, the total die size is smaller than 6900XT (with better yields because the die area is broken into smaller chiplets), so I am hoping for the same $999 MSRP on the 7900XT. AMD could realistically price it lower, but with nvidia's pricing so high up, I don't think AMD will have any incentive to do so.
My realistic guess is
7900XT = $999 to undercut the 4080, while outperforming it in rasterization.
7900XTX = $1299 to undercut the 4090, while being about 5% off in average rasterization performance (similar to 6900XT vs 3090).
From the theoretical standpoint, GPU's were always designed around high latency access to memory.
Instead of going the CPU route and optimizing for latency, GPU's just hide it by increasing the bandwidth and amount of threads.
Different tradeoffs for different workloads.
WRT to Ray Tracing; it will be interesting to see the results this time around. Just how seriously is AMD taking RT, and... if they're 20% slower than the 4090 at RT, will people say AMD still can't do RT, or similarly, if it's faster than the 4090 (which it won't be, I know), will people say Nvidia can't do RT - or that Nvidia's RT is fine (bit of a reach with that last bit I know - it's been an afternoon of analysis!!!).
also no 7950xtx will show up before the RTX4090ti
As i see it now Nvidia dedicated a lot of silicon for raytracing and they could make up rasterization difference with DLSS 3, AMD could have a lot of silicon dedicated to rasterization but lose in raytracing.
Both AMD and Nvidia sponsor a game or two to showcase new technologies or performance, that is the most you will get to see what a 450W GPU can do until another GPU generation launches but by then driver support is dead.
The performance of the GPU will be similar or identical to existing designs. There will be different tradeoffs, so games will need to be re-optimized for the new architecture, since the bottlenecks are in a different place. So expect performance in existing games to be worse, but in newer games that have access to RDNA3 GPUs to improve. Similar to other generations of GPUs, but more impactful.
More memory bus.
will wait for hopefully affordable 7600/xt
