The existence of two new AMD Radeon gaming GPUs has simply been inadvertently confirmed by the corporate, they usually appear like they will likely be based mostly on the corporate’s forthcoming RDNA 4 structure. Present rumors level to AMD leaving the excessive finish of the graphics card market to Nvidia with this technology, and specializing in mid-range efficiency as a substitute.
Though a number of of the most recent AMD GPUs are featured in our finest graphics card information, the corporate has needed to worth them very aggressively to compete with Nvidia. AMD’s present RDNA 3 GPUs are nice on the subject of easy rasterization efficiency, however Nvidia’s opponents are a lot quicker at ray tracing, and in addition get pleasure from widespread help for the corporate’s DLSS upscaling and body technology applied sciences.
Again to those new GPUs, two Navi codenames have appeared on the Github for AMD’s open-source ROCm AI software program stack, they usually each begin with the quantity 4. In case you’re not up in your AMD GPU jargon, the corporate at present makes use of “Navi” as the general codename for its GPUs, which is able to normally be utilized in a number of totally different graphics playing cards, with a few of the elements disabled on the cheaper fashions.
First up is Navi44, which comes straight after Navi33 and Phoenix, with the title “gfx1200.” That’s then adopted by Navi48, with the title “gfx1201.” On condition that, RDNA 3 chips used the Navi3x code title, and “gfx11xx” mannequin title collection, and RDNA 2 chips have been Navi2x and gfx10xx, we’re virtually sure that Navi44 and Navi48 are certainly new RDNA 4 GPUs.
The listings have been noticed by tech leaker Kepler_L2, who adopted up with a publish to substantiate that the numbers within the “gfx” mannequin names referred to the “order of growth” fairly than the dimensions or energy of the chips. We’ve seen “gfx1200” mooted as an RDNA 4 GPU title earlier than, however that is the primary time we’ve seen it married up with an precise Navi GPU.
That is the primary time we’ve seen Navi48 and Navi44 in official AMD documentation collectively, however leaks have been circulating about their specs for some time. Based on the most recent leaks, the AMD Navi48 specs embody 64 compute items, a 256-bit reminiscence bus, and a 2,770MHz clock velocity. If the RDNA 4 structure follows the same compute unit construction to RDNA 2 and RDNA 2, that may give a fully-enabled Navi48 chip 4,096 stream processors.
In the meantime, Navi44 is anticipated to have half the variety of compute items, doubtlessly which means it has 2,048 stream processors, together with a 128-bit reminiscence bus and a pair of,515MHz clock velocity. Though AMD is anticipated to depart the excessive finish to Nvidia on this technology, rumors level to AMD ray tracing bettering with RDNA 4. In fact, none of those specs have been confirmed by AMD, so take them with a pinch of salt for the second, however we do now know that Navi44 and Navi48 are undoubtedly coming.
The AMD RDNA 4 launch date is anticipated to reach earlier than the top of 2024, and it’s potential we could even discover out just a few particulars at Computex in June. Within the meantime, if you happen to’re concerned about AMD’s GPU lineup, take a look at our new Radeon RX 7900 GRE evaluation, the place we put this new mid-range champion by its paces.
