Next-Gen AMD Radeon RDNA3 Flagship To Feature 15,360 Stream Processors?
AMD's next generation RDNA3 graphics architecture generation could see a near-quadrupling in raw SIMD muscle over the current RDNA2, according to a spectacular rumor. Apparently, the company will deploy as many as 15,360 stream processors (quadruple that of a Radeon RX 6800), and spread across 60 WGPs (Workgroup Processors), and do away with the compute unit. This is possibly because the RDNA3 compute unit won't be as independent as the ones on the original RDNA or even RDNA2, which begins to see groups of two CUs share common resources.
Another set of rumors suggest that AMD won't play NVIDIA's game of designing GPUs with wide memory bus widths, and instead build on its Infinity Cache technology, by increasing the on-die cache size and bandwidth, while retaining "affordable" discrete memory bus widths, such as 256-bit. As for the chip itself, it's rumored that the top RDNA3 part, the so-called "Navi 31," could feature a multi-chip module design (at least two logic dies), each with 30 WGPs. Each of the two is expected to be built on a next-gen silicon fabrication node that's either TSMC N5 (5 nm), or a special 6 nm node TSMC is designing for AMD. Much like the next-generation "Lovelace" architecture by NVIDIA, AMD's RDNA3 could see the light of the day only in 2022.

Crypto bubble is the reason it didn't hurt.
I want a whole 300mm wafer as a single chip
mmmmm. Transistors

Will probably end-up in products the generation after this.
I think the funniest part of this will be: NVIDIA being forced to reuse another "X" GDDR tech revision for a second architecture (I hope they can at-least solve thew memory density and power issues).
I think that cache causes too many problems when you are performing random compute (so we will have to see if AMD continues their gaming-ony strategy for these parts)
RDNA was originally marketed as WGP (aka: Dual compute units). Maybe they're going to stop calling them "dual compute units" now. (60WGPs == 120CU). Which always was a "Bridge" term to help people from GCN/Vega era understand the performance of RDNA+ designs. These shader counts / core-counts are completely useless unless you're a very well studied GPU programmer. AMD 6-core Bulldozer is completely different from AMD 6-core Zen3. GPU-differences are even more pronounced.
NVidia changed the definition of "shader" in Volta/Turing: arguably double-counting because of the INT32 vs FLOAT32 simultaneous performance doo-hickey they implemented. Its all marketing. The programmers care, but the users / computer builders don't really care. Just look at FPS numbers and/or frame-times / benchmarks. The raw performance of the hardware doesn't even matter: NVidia's compiler is leagues better than AMD's compiler, so AMD has to make it up with stronger underlying hardware.
I will never complain about AMD raising prices because its been done by the competitors for far too long now. Heck people had a problem with a $50 price increase for a better product of the same level. Never understood the rage about paying $50 more to go from 3600x to 5600x. Like the performance difference is crazy.
Btw, I think they handled the CPU market quite fine. They need all the money they can get to battle 2 giants.
*my opinion
I think the price of vehicles is ridiculous for the amount of miles per gallon we still get with them, but should I blame it on everyone I see driving on the road while riding around on a bicycle?
It would be great if AMD actually launched the lower and mid range RNDA3 cards first this time around. I might eat into RNDA2 sales for RX6600 series a bit, but it would lead to a wave of efficiency increase in the right area that has the largest positive environmental impact by improving people's outdated graphics that they've clung to longer than expected due to the mining boom. It would also slow the mining boom down a bit than doing it the opposite way that has been the case for awhile.
Hey, if nvidia/amd/intel set prices and a lot of people buy, what incentive do they have to lower them?, you can't blame them. Like someone said, their business is earning as much money as they can.
Why do you think gpus like rtx 3090 exist, because people buy them.
Why do you think more and more sexy women are creating onlyfans accounts, because there are TRUCKLOADS of men willing to pay. It's not their fault (to a certain extent). If men didn't pay for it, it would not exist.
