The RDNA 3.0 architecture of the PRO W7500 includes 1792 shading units, 112 texture mapping units, 64 render output units, and 28 ray tracing cores. The Kepler architecture of the GTX 770 includes 1536 shading units, 128 texture mapping units, and 32 render output units, with no ray tracing cores. The AMD card also supports DirectX 12 Ultimate (12_2), Vulkan 1.4, and OpenGL 4.6. The NVIDIA card supports DirectX 12 (11_0), Vulkan 1.2.175, and OpenGL 4.6.

The memory subsystems differ significantly. The PRO W7500 has 8 GB of GDDR6 memory with a 128-bit bus and bandwidth of 256.0 GB/s, running at 2000 MHz (16 Gbps effective). The GTX 770 has 2 GB of GDDR5 memory with a 256-bit bus and bandwidth of 224.4 GB/s, running at 1753 MHz (7 Gbps effective). The AMD card has a boost clock of 1700 MHz and base clock of 1500 MHz, while the NVIDIA card has a boost clock of 1085 MHz and base clock of 1046 MHz.

The physical design also differs. The PRO W7500 is a single-slot card with no power connectors, measuring 216 mm in length.

Display outputs are 4x DisplayPort 2.1 on the AMD card versus 2x DVI, 1x HDMI 1.4a, and 1x DisplayPort 1.2 on the NVIDIA card.

The Verdict

The data clearly favors the AMD Radeon PRO W7500 in raw compute performance. Its average benchmark score of 16415 is higher than the 14747 of the NVIDIA GeForce GTX 770, and it ranks in the 59th percentile versus the 57th percentile for the NVIDIA card. In the two head-to-head tests, the AMD card wins both with massive margins: 270.6% in OpenCL and 258.1% in Vulkan.

The NVIDIA GeForce GTX 770 is an end-of-life product from 2013, while the AMD card is an active product from 2023. The AMD card offers a lower power draw at 70 W versus 230 W, 8 GB of memory versus 2 GB, and a more modern feature set including ray tracing cores and DirectX 12 Ultimate support. The GTX 770 retains a higher texture mapping unit count at 128 versus 112, and a wider memory bus at 256-bit versus 128-bit, but these do not translate into benchmark wins.

For any user comparing these two, the AMD Radeon PRO W7500 is the logical choice based on the recorded data. It wins every shared benchmark, has newer architecture, more memory, and a higher average score. The GTX 770 only makes sense for legacy scenarios where its older interface or specific display outputs are required.

Head-to-Head Benchmarks

The head-to-head benchmark data contains two tests, and the AMD Radeon PRO W7500 wins both. In Geekbench OpenCL, the AMD card scores 58213, while the NVIDIA GeForce GTX 770 scores 15707. The delta is 270.6%, meaning the AMD card is nearly four times faster in this test.

In Geekbench Vulkan, the AMD card scores 68634, while the NVIDIA card scores 19166. The delta is 258.1%. This is the largest margin for the AMD card in raw points, showing a difference of 49468 points.

The AMD card also has additional benchmark scores that the NVIDIA card does not have. In Passmark tests, the AMD card scores 65 in DirectX 10, 125 in DirectX 11, 46 in DirectX 12, 200 in DirectX 9, 1174 in G2D, 13368 in G3D, and 5910 in GPU Compute. The NVIDIA card has a Geekbench Metal score of 9369, while the AMD card has no Metal score listed. The AMD card does not list a Metal score, and the NVIDIA card does not list Passmark scores, so comparisons in those tests are not possible.

The average benchmark score comparison reinforces the head-to-head results. The AMD card averages 16415, while the NVIDIA card averages 14747. This is a difference of 1668 points, or approximately 11.3% higher for the AMD card.

Nearest rival data provides context. The AMD card's nearest rival is the NVIDIA RTX PRO 6000 Blackwell with an average score of 16408 and a delta of 0%. The NVIDIA GTX 770's nearest rival is the AMD Radeon RX 5500 XT with an average score of 14692 and a delta of 0.4%.

Where Each One Wins

The AMD Radeon PRO W7500 wins in computational workloads. It has a substantially higher FP32 compute at 12.19 TFLOPS versus 3.333 TFLOPS, and its FP16 capability adds 24.37 TFLOPS where the NVIDIA card has none. The pixel rate of 108.8 GPixel/s versus 34.72 GPixel/s indicates faster fill-rate operations. The texture rate of 190.4 GTexel/s versus 138.9 GTexel/s also favors the AMD card.

The AMD card wins in efficiency metrics. Its TDP of 70 W versus 230 W means it draws far less power. The suggested PSU of 250 W versus 550 W reinforces this. It also requires no power connectors, simplifying installation. The single-slot design versus dual-slot also saves space.

The AMD card wins in memory capacity with 8 GB versus 2 GB, and in bandwidth with 256.0 GB/s versus 224.4 GB/s. The GDDR6 memory type is newer than GDDR5. The AMD card also has ray tracing cores, which the NVIDIA card lacks, and supports DirectX 12 Ultimate versus DirectX 12 (11_0).

The NVIDIA GeForce GTX 770 wins in a few narrow specification areas. It has a wider memory bus at 256-bit versus 128-bit, and a higher TMU count at 128 versus 112. Its PCIe 3.0 x16 interface is wider than the PCIe 4.0 x8 interface of the AMD card. The GTX 770 also has a Metal benchmark score of 9369, which the AMD card does not list.

For use cases, the AMD card is suited for modern workloads that benefit from ray tracing, higher compute throughput, and larger memory buffers. The NVIDIA card is limited to scenarios that specifically require its older display outputs or its Metal support, though its end-of-life status means fewer modern software updates. The data shows no benchmark where the GTX 770 wins, so performance-oriented use cases should default to the AMD Radeon PRO W7500.
