AMD Radeon PRO W7700 vs AMD Radeon RX 6850M XT Comparison

Head-to-Head Benchmarks

The recorded data shows a clear overall winner: the AMD Radeon PRO W7700 takes both head-to-head benchmark victories, with a 2:0 win record over the AMD Radeon RX 6850M XT. The largest margin comes in the Geekbench Vulkan test, where the PRO W7700 scores 129,706 against the RX 6850M XT's 99,483, a 30.4% advantage. In Geekbench OpenCL, the PRO W7700 posts 108,245 versus 85,040, a 27.3% lead.

These are not trivial margins. A 30.4% gap in Vulkan indicates that the PRO W7700 delivers substantially higher graphics throughput in compute-oriented workloads that leverage the Vulkan API. The 27.3% OpenCL lead reinforces the same pattern: the desktop workstation card is consistently faster across both major cross-platform compute APIs.

The average benchmark score tells a similar story, though with a wider spread. The PRO W7700 averages 118,976 across all recorded tests, while the RX 6850M XT averages 78,940. That difference is driven partly by the RX 6850M XT's inclusion of a Geekbench Metal score of 128,981, which is its strongest single result, alongside a 3DMark Steel Nomad DX12 score of 2,257 that drags the average down. The PRO W7700's benchmark suite is limited to Geekbench OpenCL and Vulkan, both of which are strong results.

Percentile positioning also favors the PRO W7700. It sits at the 95th percentile among all GPUs in the database, while the RX 6850M XT sits at the 92nd percentile. The nearest rivals for the PRO W7700 include the NVIDIA GB10, which averages 117,393 (1.3% behind), and the NVIDIA RTX 4000 SFF Ada Generation at 117,088 (1.6% behind). The RX 6850M XT's nearest rivals are clustered much closer: the NVIDIA Tesla P100 PCIe 12 GB trails by just 0.6%, the Tesla P100 PCIe 16 GB by 0.8%, and the GeForce RTX 5090 by 1.1%. The GeForce RTX 5090 D actually leads the RX 6850M XT by 1.6%.

Where Each One Wins

The AMD Radeon PRO W7700 wins every shared benchmark category. In Geekbench OpenCL, its 108,245 score is 27.3% higher than the RX 6850M XT's 85,040. In Geekbench Vulkan, its 129,706 score is 30.4% higher than the RX 6850M XT's 99,483. There are no benchmark categories where the RX 6850M XT beats the PRO W7700 head-to-head.

However, the RX 6850M XT does have strengths outside the shared test suite. Its Geekbench Metal score of 128,981 is the highest single result in its entire benchmark record, surpassing the PRO W7700's best score of 129,706 in Vulkan only by a slim margin. In fact, the RX 6850M XT's Metal score is higher than its own OpenCL and Vulkan results by 51.7% and 29.6%, respectively. This suggests that on Apple-oriented Metal workloads, the mobile GPU is particularly capable, though no direct Metal comparison exists in the head-to-head data.

The RX 6850M XT also has a 3DMark Steel Nomad DX12 score of 2,257, a test that the PRO W7700 was not recorded in. This means the RX 6850M XT has demonstrated performance in a modern DX12 rasterization workload, while the PRO W7700's recorded data does not include that specific test.

For general compute across OpenCL and Vulkan, the PRO W7700 is the clear choice based on the recorded numbers. The RX 6850M XT's case rests on its Metal showing and its DX12 result, both of which are untested territory for the PRO W7700 in the database.

Specification Differences

The two cards differ substantially in memory configuration. The PRO W7700 has 16 GB of GDDR6 on a 256-bit bus, delivering 576.0 GB/s of bandwidth. The RX 6850M XT has 12 GB of GDDR6 on a 192-bit bus, delivering 432.0 GB/s. That is a 4 GB capacity advantage and a 144.0 GB/s bandwidth advantage for the PRO W7700.

Compute resources also favor the PRO W7700. It has 3,072 shading units, 192 texture mapping units, and 96 ROPs. The RX 6850M XT has 2,560 shading units, 160 TMUs, and 64 ROPs. The PRO W7700 also leads in ray tracing cores with 48 versus 40.

Pixel and texture throughput follow the same pattern. The PRO W7700 achieves 249.6 GPixel/s and 499.2 GTexel/s, while the RX 6850M XT achieves 165.2 GPixel/s and 413.0 GTexel/s.

Floating-point performance shows the largest relative gap. The PRO W7700 delivers 31.95 TFLOPS FP32 and 63.90 TFLOPS FP16 (2:1), while the RX 6850M XT delivers 13.21 TFLOPS FP32 and 26.43 TFLOPS FP16 (2:1). The PRO W7700 is more than double the FP32 throughput.

Clock speeds differ in an interesting way. The RX 6850M XT has a higher base clock at 2321 MHz versus 1900 MHz, and a game clock of 2463 MHz that the PRO W7700 does not list. The boost clocks are close: 2581 MHz for the RX 6850M XT and 2600 MHz for the PRO W7700. Memory clock is identical at 2250 MHz with 18 Gbps effective on both.

Power and physical specs diverge. The PRO W7700 is a dual-slot card with a 190 W TDP, one 8-pin power connector, a suggested PSU of 450 W, and dimensions of 241 mm length and 111 mm height. The RX 6850M XT is an integrated graphics processor (IGP) with a 165 W TDP, no power connectors, no suggested PSU, and no recorded dimensions. Display outputs also differ: the PRO W7700 has 4x DisplayPort 2.1, while the RX 6850M XT is "Portable Device Dependent."

Both use PCIe 4.0 x16 and support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

Architecture Differences

The PRO W7700 is built on RDNA 3.0 with the Navi 32 chip, codenamed Wheat Nas, part of the Radeon Pro Navi (Navi III Series) generation. The RX 6850M XT uses RDNA 2.0 with the Navi 22 chip, part of the Navi Mobile (RX 6000M) generation. This is a generational leap: RDNA 3.0 introduces architectural improvements over RDNA 2.0, which the benchmark data reflects in the PRO W7700's higher compute throughput.

The manufacturing process differs significantly. The PRO W7700 is fabricated on TSMC's 5 nm node, while the RX 6850M XT uses TSMC's 7 nm node. Transistor counts reflect this: the PRO W7700 packs 28,100 million transistors on a 346 mm² die, yielding a transistor density of 81.2M per mm². The RX 6850M XT has 17,200 million transistors on a 335 mm² die, a density of 51.3M per mm². The PRO W7700 fits roughly 63% more transistors into a die that is only 11 mm² larger.

The PRO W7700's release date is 2023-11-12, and its predecessor is the Radeon Pro Vega. The RX 6850M XT was released on 2022-01-03, has a predecessor of Polaris Mobile, and is marked end-of-life. The PRO W7700 has a launch MSRP of 999 USD, while the RX 6850M XT has no recorded launch MSRP.

The PRO W7700's 48 ray tracing cores and 3,072 shading units, combined with the RDNA 3.0 architecture, explain its higher FP32 throughput of 31.95 TFLOPS versus 13.21 TFLOPS. The RX 6850M XT's higher base clock (2321 MHz versus 1900 MHz) partially compensates for its lower shader count, but not enough to close the compute gap.

The Verdict

The AMD Radeon PRO W7700 is the faster GPU in every directly comparable benchmark. Its Geekbench OpenCL score of 108,245 and Vulkan score of 129,706 both exceed the RX 6850M XT's corresponding results by more than 27%. Its average benchmark score of 118,976 is about 51% higher than the RX 6850M XT's 78,940, and it ranks in the 95th percentile versus the 92nd percentile. For anyone choosing between these two based on recorded data, the PRO W7700 is the straightforward pick for OpenCL and Vulkan compute workloads.

The RX 6850M XT is not without merit, however. Its Geekbench Metal score of 128,981 outshines all of its own OpenCL, Vulkan, and DX12 results, and it stands as the sole data point suggesting the mobile card can reach near-130,000-level performance in the right API environment. The RX 6850M XT also holds a 3DMark Steel Nomad DX12 score of 2,257, a result that the PRO W7700 has no recorded equivalent for. These are meaningful distinctions for niche use cases, but they do not overturn the head-to-head results.

Choose the PRO W7700 if your workflows rely on OpenCL, Vulkan, or general compute acceleration, since its 16 GB memory, 576.0 GB/s bandwidth, and 31.95 TFLOPS FP32 throughput give it a strong foundation across the board. Choose the RX 6850M XT only if Metal compatibility is essential and the PRO W7700's lack of a recorded Metal score is a concern, or if you specifically need its 3DMark Steel Nomad DX12 performance.

The specification differences reinforce the verdict. The PRO W7700 leads in memory capacity, bandwidth, shader count, texture units, ROPs, ray tracing cores, pixel rate, texture rate, and FP32/FP16 throughput. The RX 6850M XT leads only in base clock speed and game clock, and it has a slightly lower TDP at 165 W versus 190 W. The PRO W7700 is the larger, dual-slot desktop card with display outputs, while the RX 6850M XT is an IGP with portable-device-dependent outputs.

The database indicates a decisive overall win for the AMD Radeon PRO W7700, with a 2:0 record and a 27-30% performance margin in every shared benchmark.
