A bunch of AMD Radeon 8000 specs have simply apparently been leaked on-line, probably giving us a much bigger image of what’s to come back with the forthcoming AMD RDNA 4 graphics card launch. All 4 of the brand new playing cards look like primarily based on the Navi44 and Navi48 chips which have already appeared in listings elsewhere, but it surely seems like we now even have some details about the VRAM speeds, cache, and reminiscence interfaces.
AMD is anticipated to launch its new lineup of RDNA 4 GPUs at CES in January 2025, with rumors pointing to the corporate specializing in mid-range efficiency with this collection of GPUs, leaving the last word finest graphics card title to the Nvidia RTX 5090.
This newest rumor comes from common tech leaker All The Watts!! who, as traditional, has offered a cryptic collection of numbers in a submit on X (previously Twitter). It seems as if six merchandise are detailed, and All The Watts!! has helpfully offered some emoji clues to the final two. One has an owl and an angel, which we assume means Strix Halo CPU with its mighty built-in GPU, and the opposite has a US flag and a valley, which we assume refers to AMD’s rumored Sonoma Valley cell chip, which is anticipated to be much less highly effective than Strix Halo.
The highest 4 merchandise, nevertheless, look very very like they may confer with new RDNA 4 graphics playing cards, so let’s check out them. The primary set of numbers in every entry is both a 44 or a 48, which we will solely assume refers to Navi44 and Navi48. If that is true, we’re trying on the specs for 4 GPUs primarily based on Navi48, and one primarily based on Navi44. Subsequent up is a three-digit quantity, which is both 128, 192, or 256. These look very very like the figures for the width of the reminiscence interface on every GPU, with a 256-bit bus offering extra bandwidth than a 128-bit bus.
The third set of numbers is trickier. They every have two digits, that are both 64, 48, or 32. This might probably confer with the quantity of L3 cache in every GPU in megabytes. Nevertheless, it may additionally confer with the variety of compute items enabled in every GPU. Not one of the numbers are 56, although, and we’ve already seen a Navi48 GPU with 56 compute items seem within the Geekbench outcomes browser. This makes us suppose these figures usually tend to confer with the quantity of L3 cache within the GPU.
Lastly, the fourth set of numbers every have two digits, that are both 18, 19, or 20, and these figures look very very like they’re referring to the efficient pace of the VRAM in GHz (or, extra precisely, Gbps), as additionally proven in a current submit by Kepler_L2. What does this all imply? Properly, if we’ve accurately recognized these specs, and AMD sticks to its earlier naming conventions, we will begin to paint an image of how these new playing cards may look.
With all this in thoughts, these are the estimated AMD Radeon 8000 specs:
| 8800 XT | 8800 | 8700 XT | 8600 XT | |
| GPU | Navi48 | Navi48 | Navi48 | Navi44 |
| Reminiscence interface | 256-bit | 256-bit | 192-bit | 128-bit |
| L3 cache | 64MB | 64MB | 48MB | 32MB |
| VRAM pace | 20Gbps | 18Gbps | 19Gbps | 18Gbps |
There’s not a lot distinction between the specs of the highest two GPUs right here, however AMD may differentiate these two playing cards additional by disabling a couple of of the compute items on the GPU – this might make the distinction between an XT with 60 CUs and non-XT GPU with 56 CUs, which could be known as the Radeon RX 8800 and 8800 XT, for instance. You could possibly then have a Radeon RX 8700 XT with maybe 48 CUs, and an 8600 XT with 32 CUs. That is all pure hypothesis, although.
Certainly, keep in mind that completely none of this has come formally from AMD, and we’re nonetheless very a lot on the rumor and hypothesis stage. We’ll have to attend till AMD formally lifts the lid on its new GPUs earlier than we all know all the main points for positive. Within the meantime, try our AMD Zen 5 information, to see the main points of AMD’s new CPU lineup.
