AMD Radeon Pro W7700 16GB Launches at $999

The AMD Radeon Pro W7700 16GB was revealed today at the Supercomputing 2023 conference. This will be AMD's first Navi 32-based workstation GPU, with a price of $999, and it should be available for purchase soon. (AMD lists a Q4 2023 timeframe, one which we're already sitting in.)

As a workstation part, we expect significantly higher prices than consumer GPUs. The core specifications appear to be roughly on par with the Radeon RX 7800 XT, which costs half as much, but with drivers that are better tuned for professional workloads. AMD dug itself a bit of a hole, however, as it already has a W7800 professional part, so it had to use the W7700 name on the newcomer. Here's a rundown of the specifications from the various Radeon Pro W7000-series parts.

The new W7700 provides an interesting blend of potential performance and features. It has the same memory bandwidth as the W7800, for example, but half the capacity. It also has the same amount of Infinity Cache (L3). That's because both configurations use four MCDs (Memory Cache Dies), though the W7800 has the larger Navi 31 GCD (Graphics Compute Die) while the W7700 uses Navi 32. But the price of the W7700 lands significantly below the high-end professional GPUs at just $999.

AMD was quick to make comparisons with Nvidia's professional GPU lineup, and as you'd expect for such comparisons, the W7700 delivers better performance at a lower price. SPECviewperf is one of the examples, and AMD's own numbers put the aggregate performance of the W7700 well ahead of the previous generation Nvidia parts, and also ahead of the Nvidia 4000 SFF Ada.

One aspect of the performance and specifications comparison that's not in AMD's favor is the power use. The 4000 SFF Ada only needs 70W, compared to 190W for the W7700. It's not as big of a gap against Nvidia's previous generation A5000, A4500, and A4000, though it's odd that AMD wouldn't include Nvidia's newer RTX 5000, 4500, and 4000 parts in that comparison.

By choosing to stick with a single GDDR6 chip per MCD, AMD's normal memory capacity advantage that we see in the consumer sector evaporates. The W7800 sits at a full 32GB (two 2GB chips per MCD), while the W7700 cuts that in half to 16GB. Nvidia's competing parts thus end up with a memory capacity advantage, though that doesn't mean they'll always be faster.

AMD's own tests show the W7700 slightly passing the Nvidia A5000 in SPECviewperf, though we don't get the individual numbers for that GPU. The W7700 also has a healthy lead in every individual test, with the exception of Siemens NX where it comes in slightly behind the A4000 and A4500. That's an interesting change compared to consumer parts, where the Nvidia GPUs really struggle in that particular workload — check out our RX 7700 XT Professional Tests for more details.

Besides performance metrics, AMD also offers four DisplayPort 2.1 UHBR13.5 ports (54 Gbps each) on the W7700, while the W7800 and W7900 each have a single UHBR20 port (80 Gbps) along with the three UHBR13.5 ports. Nvidia GPUs all remain with DisplayPort 1.4a connectivity, which means they have to depend on Display Stream Compression functionality for higher refresh rates and resolutions.

There are additional benchmarks from AMD, along with other information, in the full slide deck, which we've included below for reference.
