AMD Radeon PRO W6600 vs NVIDIA GeForce RTX 5070 Ti Comparison

Where Each One Wins

The NVIDIA GeForce RTX 5070 Ti dominates the shared benchmark suite without exception. Across the two directly comparable tests, the GeForce card wins both, leaving the AMD Radeon PRO W6600 without a single head-to-head victory. The RTX 5070 Ti posts a Geekbench OpenCL score of 212,363 against the Radeon's 73,514, and a Geekbench Vulkan score of 225,122 against 78,428. The margin is substantial in both cases, with the NVIDIA part leading by roughly 65% in each test.

The Radeon PRO W6600 does hold a notable position in the broader database, however. Its average benchmark score of 81,995 places it in the 92nd percentile of all GPUs, which is higher than the RTX 5070 Ti's 86th percentile ranking. This reflects the AMD card's strong showing in its own benchmark set, which includes Geekbench Metal, OpenCL, and Vulkan results. The W6600's nearest rivals in the database are the AMD Radeon Pro Vega 64X (1.3% lower average score), the NVIDIA GeForce RTX 5090 (2.7% lower), and two Tesla P100 variants (3.0% and 3.3% lower). The RTX 5070 Ti, by contrast, sits near the AMD Radeon RX Vega 64 (0.1% difference), Intel Arc A550M (0.4% ahead), AMD Radeon RX 6900 XT (2.0% behind), and AMD Radeon RX 6800 XT (3.1% ahead).

The use-case split is therefore clear. The RTX 5070 Ti is the compute and graphics powerhouse for workloads that leverage OpenCL or Vulkan, which are common in general-purpose GPU compute and cross-platform graphics. The Radeon PRO W6600, despite losing the head-to-head, shows competitive standing in its own right, particularly in Apple-centric Metal benchmarks where it scores 94,042. For users whose workloads align with the Radeon's benchmark set, it remains a viable workstation part, but the data does not show any test where it beats the RTX 5070 Ti.

Architecture Differences

The two cards come from different design generations and process nodes. The AMD Radeon PRO W6600 uses the Navi 23 chip built on RDNA 2.0 architecture, fabricated on TSMC's 7 nm process. It packs 11,060 million transistors into a 237 mm² die, yielding a transistor density of 46.7 million per square millimeter. The NVIDIA GeForce RTX 5070 Ti uses the GB203 chip on Blackwell 2.0 architecture, fabricated on TSMC's 5 nm process. It contains 45,600 million transistors across a 378 mm² die, giving a transistor density of 120.6 million per square millimeter. The NVIDIA chip is roughly four times denser in transistor count and over 2.5 times denser per area.

Memory configurations differ sharply. The Radeon PRO W6600 has 8 GB of GDDR6 on a 128-bit bus, delivering 224.0 GB/s of bandwidth. The RTX 5070 Ti has 16 GB of GDDR7 on a 256-bit bus, delivering 896.0 GB/s, exactly four times the bandwidth. The NVIDIA card also runs its memory at 28 Gbps effective, double the Radeon's 14 Gbps effective.

Compute resources are heavily skewed toward the NVIDIA card. The RTX 5070 Ti has 8,960 shading units, 280 texture mapping units, 96 ROPs, 70 ray tracing cores, and 280 tensor cores. The Radeon PRO W6600 has 1,792 shading units, 112 TMUs, 64 ROPs, and 28 ray tracing cores, with no tensor core count listed. The NVIDIA card's FP32 throughput is 43.94 TFLOPS against the Radeon's 9.247 TFLOPS, a near fivefold difference. FP16 performance is also higher on NVIDIA at 43.94 TFLOPS (1:1 ratio) versus 18.49 TFLOPS (2:1 ratio) on AMD.

Clock speeds are relatively close. The Radeon runs at 2331 MHz base and 2580 MHz boost, while the RTX 5070 Ti runs at 2295 MHz base and 2452 MHz boost. The AMD card actually has the higher clock rates, but the NVIDIA card's massive shader count overwhelms that advantage. The Radeon achieves a pixel rate of 165.1 GPixel/s and texture rate of 289.0 GTexel/s, while the RTX 5070 Ti reaches 235.4 GPixel/s and 686.6 GTexel/s.

Physical and power characteristics also differ. The Radeon PRO W6600 is a single-slot card with a 100 W TDP and a single 6-pin power connector, requiring a 300 W power supply. It measures 241 mm (9.5 inches) in length. The RTX 5070 Ti is dual-slot with a 300 W TDP, a single 16-pin connector, and a 700 W power supply recommendation. It measures 304 mm (12 inches) in length, 137 mm (5.4 inches) in height, and 48 mm (1.9 inches) in width. The Radeon uses PCIe 4.0 x8, while the RTX 5070 Ti uses PCIe 5.0 x16.

Display outputs differ as well. The Radeon PRO W6600 offers four DisplayPort 1.4a outputs. The RTX 5070 Ti offers one HDMI 2.1b and three DisplayPort 2.1b outputs. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

Head-to-Head Benchmarks

The head-to-head data contains two directly comparable tests, both won by the NVIDIA GeForce RTX 5070 Ti. In Geekbench OpenCL, the RTX 5070 Ti scores 212,363 against the Radeon PRO W6600's 73,514, a delta of 65.4% in NVIDIA's favor. In Geekbench Vulkan, the RTX 5070 Ti scores 225,122 against 78,428, a delta of 65.2%. These are consistent margins, indicating the NVIDIA card is roughly three times faster in raw compute throughput across both OpenCL and Vulkan workloads.

The Radeon PRO W6600's own benchmark results show where it performs best. Its Geekbench Metal score of 94,042 is its highest recorded result, followed by Vulkan at 78,428 and OpenCL at 73,514. The Metal advantage over OpenCL is about 28%, suggesting the Radeon is better optimized for Apple's compute framework than for cross-platform APIs. The RTX 5070 Ti, by contrast, scores higher in Vulkan (225,122) than OpenCL (212,363), a 6% difference. It also has a substantial Passmark suite, led by a G3D score of 32,974, GPU compute score of 20,203, G2D score of 1,332, and DirectX 9 through 12 scores ranging from 127 to 351.

The data shows that the RTX 5070 Ti's win margins are large enough to classify it in a different performance tier. A 65% lead in both head-to-head tests is not a marginal edge; it represents a fundamental throughput advantage that no amount of driver optimization on the Radeon side is likely to close. The Radeon's higher percentile ranking (92nd versus 86th) is a function of its benchmark set, not its head-to-head competitiveness.

The Verdict

The benchmark data is unambiguous. The NVIDIA GeForce RTX 5070 Ti is the faster card by a wide margin in every directly comparable test. Its OpenCL and Vulkan scores are both roughly three times higher than the Radeon PRO W6600's, and its memory bandwidth is four times higher at 896.0 GB/s versus 224.0 GB/s. Its FP32 throughput of 43.94 TFLOPS dwarfs the Radeon's 9.247 TFLOPS. For any workload that uses OpenCL or Vulkan, the RTX 5070 Ti is the clear choice.

The Radeon PRO W6600 should be selected only in specific circumstances. It is a single-slot, 100 W card, making it suitable for space-constrained or power-limited systems where the 300 W, dual-slot RTX 5070 Ti would not fit or would require a larger power supply. Its 92nd percentile ranking and strong Metal score of 94,042 suggest it remains competitive in Apple-centric environments. Its nearest rivals in the database are all within 3.3% of its average score, indicating tight competition in its own tier.

The RTX 5070 Ti's nearest rivals, by contrast, include the AMD Radeon RX 6900 XT and RX 6800 XT, with the GeForce sitting between them in average score. The RTX 5070 Ti is also the newer product, released in February 2025 versus June 2021 for the Radeon, and it remains in active production while the Radeon is end-of-life. The RTX 5070 Ti's successor is the GeForce 60 series, but that does not diminish its current standing. For general-purpose compute and modern gaming, the RTX 5070 Ti is the superior product. The Radeon PRO W6600 is a legacy workstation card that, while still competitive in its niche, cannot match the NVIDIA card's raw performance.
