AMD has unveiled the professional versions of its previously launched RDNA 3 graphics cards. The Radeon Pro W7900 and W7800 join the lineup, prepared to do actual work instead of goofing off with games like their siblings. The two cards mimic the launch of the previous GPUs, as there’s a flagship and a cut-down version available. The headline features include RDNA 3 architecture and 48GB and 32GB of GDDR6 memory.
The top-tier model is the Radeon Pro W7900, and as expected, it’s a Pro version of the Radeon RX 7900 XTX. It has the same 96 compute units (CU), 6,144 stream processors (SP), and 61 TFLOPS of single-precision compute performance. It has a 384-bit memory bus but doubles the amount to 48GB. Both cards share the same 96MB of Infinity Cache. Despite the similarities, AMD has reduced its TGP from 355W in the amateur card to 295W in the Pro card. The only significant difference, aside from certified drivers for specific applications, is the Pro card features a three-slot blower design, making it the first triple-slot Radeon card.

Though the W7900 Pro shares a lot of hardware with its Radeon uncle, that’s not the case with the W7800. It is remarkably cut down compared with the Radeon RX 7900 XT, as denoted by the number 8 instead of 9 in its title. It’s not in the same class, featuring just 70 CUs compared with the Radeon’s 84. It does feature 32GB of GDDR6 memory instead of the XT’s 20GB, but it’s on a narrower memory bus. The XT sports a 320-bit memory bus, compared to the W7800’s 256-bit bus. These changes allow it to produce 45 TFLOPs of compute compared with 52 TFLOPs with the XT GPU.

It’s tempting to think the W7800 might be the first glimpse of Navi 32, one rung below Navi 31 used in the 7900 cards, but it’s not, according to HotHardware. The W7800 has 70 CUs, and Navi 32 has been tipped to offer just 64; it’ll probably also feature a 256-bit memory bus. That is the GPU that will be used for the Radeon RX 7800 and 7700 cards, and it is currently AWOL as there’s been no word on when it might arrive.

Both cards are priced to move, with the W7800 going for $2,499 and the W7900 at just $3,999. That’s surprisingly affordable for workstation GPUs, and this seems to be how AMD plans on attacking Nvidia—on price instead of performance. It openly recognizes in the chart above it can’t compete with the A6000 Ada Lovelace card but notes that the Ada card costs more than twice as much as its flagship offering. Despite costing less, they’re also very competitive with the company’s Ampere workstation cards.
