Expecting AMD to match Nvidias performance across the range with a £50/$50 discount, that's all they do these days. Nothing like the 4870 smashing Nvidias head in anymore.
Got excited and disappointed for rdna 1 & 2 already.

AMD also start dividing leagues similar way to Nvidia... Navi 21 class rx 6800xt already a league down as Navi 32 7800xt.

They've been so quiet and not much rumours "leaked" as competitor, let's hope to get surprised.
 
Well potentially RDNA3 sounds like it should be considerably cheaper to produce, that “should” lead to much more competitive pricing.

However, time will tell.

I was tempted to go balls out and get a 4090, up until the GTC announcement anyway. No chance now after seeing the pricing and then finding out about the need for a new PSU.

My 1KW PSU should be enough but it turns out that’s not the problem.
 

RTX 4000 against RDNA 3: Experts see important cost advantages for AMD​


On 03.11. AMD wants to present its new RDNA 3 models, which should be much cheaper to produce for the manufacturer. By abandoning complex and large accelerator units for ray tracing and AI and switching to smaller dies, yields increase and costs decrease. For the first time in the last decade, AMD is said to actually achieve cheaper manufacturing than Nvidia, which is struggling to maintain high margins as AMD positions its new products and prepares to capture an estimated market share of more than 30 percent in the graphics card space .

Lets hope they don't this time as the goals are now double the size from their last miss. They will not have another opportunity like this in years to come.

They bluffed about the stock last time, but the biggest mistake was not releasing MBA stock of all the SKU's to the UK market through retailers. I would quite happily have tried for a 6800/XT knowing there were bursts coming (for msrp), however after the launch it was just AIB offers which were constantly climbing in £££. I mean it was that bad a 6700XT was in stock but for £700+. 6800's and 6900's were well over a grand.

They could really pepper the market and smash nvidia hard if they priced the 7800 @ £699 and the 7900 @ £999.

Based on the above article, I reckon amd will do very well going forward for the next couple of years (after all, peoples main focus atm seems to be bang per buck, power efficiency, raster and vram, amd can easily nail all of these) but at the same time, it seems they still aren't taking AI and ray tracing seriously, which is a massive oversight imo (RDNA 2 was great but not having any strengths in these areas killed it imo, ignoring lack of stock and chance of getting them for MSRP on launch....) and could cost them big time in the long run as was the case with their dx 11 and rasterization performance compared to nvidia over the years.

Back on rdna 2/ampere release, it wasn't "that" valuable but given all the games that have ray tracing now and it's clear what way the game industry is heading (it's not just nvidia backing it as some would have you believe), can't help but feel this may end up being another dx 11, opengl etc. mishap for amd in the long run. Whilst many don't care for RT now, whether they like it or not, it will become the standard with raster eventually getting phased out and nvidia so far have a huge head start on it, of course we are talking about the long run here i.e. in 5, maybe 10 years so not a "major" issue for "now".

Who knows though, maybe they will have some magic happening in their drivers to pull of some RT performance gain and a competitor for dlss 3/frame generation....

This is why we badly need intel to be a success in the gpu space too, just having 2 players in it is ****, always compromises of some kind.

As it is, it's looking likely that I'll skip both rdna 3 and ada.

I'm going to assume those shaders (cores) are not the same IPC, like Ampere vs Turing there are a lot more shaders but individually lower performance, but each shader also has an RT core and an FP unit, so like Ampere the compute throughput should increase in line with the core count, as well as the RT performance, and then the higher clock speed on top of that.
So its not going to be >3X the raster performance, but RT might be.

the AMD Navi 31 GPU with RDNA 3 architecture is expected to offer a single GCD with 48 WGPs, 12 SAs, and 6 SEs. This will give out a total of 12,288 SPs or stream processors. This is an increase of 2.4x in cores compared to the 5120 SPs featured on the Navi 21 GPU.


The Navi 31 GPU will also carry 6 MCD's which will feature 16 MB Infinity Cache per die and are also likely to carry the 64-bit (32-bit x 2) memory controllers that will provide the chip with a 384-bit bus interface.

While this equals 96 MB of Infinity Cache which is lower than the 128 MB featured on the current Navi 21 GPUs, there's also a 3D-Stacked solution in the works which was pointed out recently and that would double the Infinity Cache with 32 MB (16 MB 0-hi + 16 MB 1-hi) capacities for a total of 192 MB of cache. This is a 50% increase versus the current Navi 21 design and it also makes Navi 31 the first GPU with both, chiplet and 3D stacked designs.

The two major players being related too is worrying.

but

Su and Nvidia co-founder and CEO Jen-Hsun Huang have been described as cousins or niece and uncle; however, she has dismissed these claims as "not true".

but

"Technically, Lisa Su's grandfather is Jen-Hsun Huang's uncle. They are not exactly niece and uncle, but close relatives."


So related.
