AMD announced the launch of three W6000X series It will be designed specifically for Apple’s Mac Pro.Therefore, these will not be Best graphics card, Unless we are talking about Apple’s best GPU. The lineup includes W6900X, W6800X and W6800X Duo, using AMD’s latest RDNA 2 architecture and up to 64GB and 128GB memory configuration, suitable for Duo.
Compared with the current W5000X products, these new GPUs will bring major graphics upgrades to the Mac Pro, and the performance is twice to nearly four times that of the current Radeon Pro RX W5700X. Considering how fast these new GPUs are, the performance of the lowest teir card W6800X is almost twice that of W5700X, with a performance of 32 Teraflops, while the previous flagship W5700X is only 18.9 Teraflops.
W6800X will become the entry-level graphics card in the W6000X series, and its specifications are Radeon RX 6800 Desktop equivalent-it is also basically the same as Radeon Pro W6800, Except for Apple-centric themes to lower the clock slightly. W6800X has 60 CUs, a total of 3840 stream processors, and a peak clock speed of 2087MHz. The card will run on a 256-bit wide memory bus with 32GB GDDR6 memory and 128MB Infinity Cache.
W6900X is an intermediate GPU option with 80CU and 5120 stream processors, similar to RX 6900 XTThe memory remains unchanged, 32GB of GDDR6 runs on a 256-bit wide bus and 128MB of infinite cache.
Finally, AMD’s highest-level option is W6800X Duo, which is the most exotic graphics card in the series, with a dual GPU configuration running on a single daughter board. As the name suggests, the W6800X Duo has two W6800X GPUs, which are interconnected by AMD’s Infinity Fabric. As a result, the number of stream processors and memory has doubled to 120 CUs, 7680 stream processors and 64GB of GDDR6 memory. However, due to the complexity of running two GPUs on one board and the lower 400W (relative to 300W) TDP, the clock speed has been slightly reduced to the peak clock of 1979MHz.
| Model | CU: | Stream processor | Memory interface | Performance: | Unlimited cache | GDDR6 memory configuration: | TGP (total graphics capability): |
| Radeon PRO W6900X | 80 | 5120 | 256 bit | 22 FP32 TFLOP | 128MB | 32GB | 300W |
| Radeon PRO W6800X | 60 | 3840 | 256 bit | 16 FP32 TFLOP | 128MB | 32GB | 300W |
| Radeon PRO W6800X Duo | 120 | 7680 | 256 bit (per GPU) | 30.2 FP32 TFLOP | 256MB (128MB per GPU) | 64GB (32GB per GPU) | 400W (total) |
Since AMD’s W6000X GPU is unique to Mac Pro, these “graphics cards” will use MPX modules. These modules are designed to be installed in the Mac Pro chassis and have additional connectors on the PCB to support multi-GPU configurations and to power multiple Thunderbolt 3 ports on each W6000X series GPU.
Speaking of multi-GPU configurations, Mac Pro allows up to two W6000X MPX modules to be inserted into its chassis. This also includes W6800X Duo, which means you can set up Quad-GPU in Mac Pro.
The cooling solution for each workstation GPU is also custom-designed for Mac Pro. Each MPX module packs a matte black passive radiator, which is cooled by the Mac Pro chassis fan.
But the pricing will be very steep, just like Apple’s products. Using W6800X to build Mac Pro will cost $2,400 more than the benchmark Radeon Pro 580X, $5600 for W6900X, and $4600 for W6800X Duo. Not to mention the dual GPU settings, the price of these settings is more than twice these prices.
