We now have details on what AMD will start to compete against Nvidia, from an uncommon resource. Newegg publishes its individual graphics and computing guides, such as a guide to which GPU you ought to purchase. Incorporated in that guide, at the very least briefly? Specs for AMD’s impending Radeon RX 6700 XT, 6800 XT, and 6900 XT GPUs.
Naturally these specs ought to be regarded preliminary, but they line up with other rumors we have heard about the family members. Hat-tip to Videocardz for obtaining the facts:
There are some oddities in the chart that are difficult to reveal. The Radeon 6700 XT is a marked downgrade from the 5700 XT, with considerably less clock, considerably less RAM, considerably less memory bandwidth, and — admittedly — a extremely wonderful TDP of 150W. We can visualize that some of RDNA2’s overall performance-for each-watt uplift will get the job done in AMD’s favor below, but the scaled-down RAM buffer is a minor shocking. AMD might have offset the clock drop and memory bandwidth reduction with far more cache and greater performance, but there’s no way to offset decreased VRAM.
It is doable that the 6700 XT will be presented in a 6GB and 12GB taste, related to GPUs like the RX 570. One more leak — this one particular from Reddit — offers some greater clock information courtesy of Apple’s macOS 11 beta.
We really don’t know if these figures are correct both, but they suggest a Navi 21a and 21b. 21a has a highest frequency of 2050MHz, whilst 22b has a leading frequency of 2200MHz. Socket electricity limits are supplied as 200W and 238W respectively. This implies it usually takes 1.19x far more electricity to generate 1.07x far more overall performance on the chip. The fact that the Apple chart refers to socket electricity could signify this is only the electricity draw for the chip itself, not the rest of the card. If we believe that, the TDP listings from Newegg and Apple are a little bit closer to every other.
A number of months in the past, I wrote that if AMD could boost its main clocks up to 2.2GHz (equal to the PS5), it could assistance the company sq. off with the RTX 3080. The GPU could decide on up 1.22x overall performance from the added clock (assuming a 1.85GHz – 2.2GHz jump). We know overall performance ought to just about double from the main rely boost, even though the jump will not be beautifully linear. Presented that the RTX 3080 is about 2x more quickly than the 5700 XT in various exams, AMD might be able to land a aggressive GPU for Ampere in terms of raw overall performance, even though obviously electricity use and thermals will be their individual matters. It is too early to know if the early troubles we’re listening to about with GeForce RTX 3080 shipments will have an impact on comparisons when RDNA2 launches or not.
We know that Nvidia is declaring a 1.9x overall performance/watt advancement above Turing, compared to AMD’s 1.5x enhanced overall performance for each watt above RDNA. It is likely to be extremely attention-grabbing to see how the two businesses assess against every other when playing cards drop in the not-so-distant upcoming.
