AMD Radeon Pro W6600X vs NVIDIA Tesla T4 Comparison

Head-to-Head Benchmarks

The recorded database contains no direct head-to-head benchmark entries for the AMD Radeon Pro W6600X and the NVIDIA Tesla T4. Instead, the comparison must be built from the two cards' separate benchmark results. The AMD Radeon Pro W6600X holds a single Geekbench Metal score of 107,342. The NVIDIA Tesla T4 reports two scores: 61,276 in Geekbench OpenCL and 72,190 in Geekbench Vulkan. Its average benchmark score across those two tests is 66,733.

The AMD card's Metal result places it 60.9% above the Tesla T4's average score. That is a substantial margin, but the comparison is not perfectly aligned because the workloads differ by API. The Tesla T4's Vulkan score of 72,190 is 17.8% higher than its own OpenCL result, indicating that the NVIDIA card responds differently depending on the compute interface. The AMD card's single Metal score cannot be directly mapped to either OpenCL or Vulkan, so the cleanest interpretation is that the Radeon Pro W6600X delivers roughly 61% higher performance in its native Metal environment than the Tesla T4 does on average across its two recorded tests.

The percentile rankings reinforce this gap. The AMD Radeon Pro W6600X sits in the 94th percentile among all GPUs in the database. The NVIDIA Tesla T4 sits in the 90th percentile. Both are high performers, but the AMD part is four percentile points higher, which aligns with the raw score difference.

Looking at the nearest rivals for each card provides additional context. The AMD Radeon Pro W6600X's closest neighbors in the database are the AMD Radeon Pro Vega II Duo at 106,750 (0.6% below the W6600X), the AMD Radeon Pro Vega II at 109,617 (2.1% above), the AMD Radeon PRO W7900 at 110,725 (3.1% above), and the NVIDIA Quadro RTX 6000 at 101,872 (5.4% below). This cluster shows the W6600X is tightly grouped with some of the fastest workstation cards in the database, with all four rivals within roughly 5.4% of its score.

The NVIDIA Tesla T4's nearest rivals are the AMD Radeon VII at 66,004 (1.1% below), the NVIDIA Tesla P40 at 65,095 (2.5% below), the AMD Radeon Instinct MI25 at 68,562 (2.7% above), and the Intel Arc A770 at 68,809 (3.0% above). The T4's position in this group is less distinctive, as its nearest rivals span a narrower range of roughly 3% above and 2.5% below. The data suggests the W6600X belongs to a higher performance tier, while the T4 sits in a mid-range server compute tier.

Architecture Differences

The two cards come from different manufacturers and different design generations. The AMD Radeon Pro W6600X uses the Navi 23 chip built on the RDNA 2.0 architecture, while the NVIDIA Tesla T4 uses the TU104 chip built on the Turing architecture. Both are manufactured by TSMC, but on different process nodes. The AMD card uses a 7 nm process, while the NVIDIA card uses a 12 nm process. That difference in process geometry helps explain the transistor density gap: the AMD chip packs 11,060 million transistors into a 237 mm² die, yielding a density of 46.7 million transistors per square millimeter. The NVIDIA chip contains 13,600 million transistors across a much larger 545 mm² die, giving a density of 25.0 million transistors per square millimeter. The AMD chip is therefore roughly 87% denser in terms of transistor packing, despite having fewer total transistors.

The memory configurations differ substantially. The AMD Radeon Pro W6600X has 8 GB of GDDR6 memory on a 128-bit bus, with a memory clock of 2000 MHz (16 Gbps effective) and bandwidth of 256.0 GB/s. The NVIDIA Tesla T4 has 16 GB of GDDR6 memory on a 256-bit bus, with a memory clock of 1250 MHz (10 Gbps effective) and bandwidth of 320.0 GB/s. The Tesla T4 therefore has double the memory capacity and 25% more bandwidth, but it achieves that with a wider bus and lower effective memory speed.

Compute unit counts also differ. The AMD card has 2048 shading units, 128 texture mapping units, and 64 render output units. It includes 32 ray tracing cores but no tensor cores. The NVIDIA card has 2560 shading units, 160 texture mapping units, and 64 render output units. It includes 40 ray tracing cores and 320 tensor cores. The NVIDIA card has 25% more shading units and 25% more texture units, while both have the same number of render output units. The tensor core count is a notable differentiator, as the Tesla T4 is designed for inference workloads that leverage tensor operations, while the AMD card has no equivalent hardware.

Clock speeds are not comparable in the traditional sense because the two cards run at very different base and boost frequencies. The AMD card has a base clock of 2068 MHz and a boost clock of 2479 MHz. The NVIDIA card has a base clock of 585 MHz and a boost clock of 1590 MHz. The AMD card's boost clock is 55.9% higher than the Tesla T4's boost clock, which helps explain the AMD card's higher compute throughput despite having fewer shading units.

The compute rates reflect these architectural choices. The AMD Radeon Pro W6600X delivers 10.15 TFLOPS of FP32 performance and 20.31 TFLOPS of FP16 performance (2:1 ratio). The NVIDIA Tesla T4 delivers 8.141 TFLOPS of FP32 and 16.28 TFLOPS of FP16 (also 2:1). The AMD card is 24.7% ahead in FP32 and 24.8% ahead in FP16. Pixel fill rate favors the AMD card at 158.7 GPixel/s versus 101.8 GPixel/s for the NVIDIA card, a 55.9% advantage. Texture fill rate also favors AMD at 317.3 GTexel/s versus 254.4 GTexel/s, a 24.7% advantage.

Power consumption is another clear split. The AMD card has a TDP of 120 W and the NVIDIA card has a TDP of 70 W. The AMD card's power draw is 71.4% higher, but it delivers substantially higher raw compute performance per the recorded rates. The suggested PSU is 300 W for the AMD card and 250 W for the NVIDIA card. The physical format differs too: the AMD card is dual-slot with an Apple MPX bus interface, while the NVIDIA card is single-slot with a PCIe 3.0 x16 interface. The NVIDIA card is 168 mm (6.6 inches) long and requires no power connectors, while the AMD card lists no power connector details and no dimensions. Both cards have no display outputs.

Where Each One Wins

The AMD Radeon Pro W6600X wins clearly on raw compute throughput. Its FP32 result of 10.15 TFLOPS is 24.7% above the Tesla T4's 8.141 TFLOPS. Its FP16 result of 20.31 TFLOPS is 24.8% above the Tesla T4's 16.28 TFLOPS. Its pixel fill rate of 158.7 GPixel/s is 55.9% above the Tesla T4's 101.8 GPixel/s. Its texture fill rate of 317.3 GTexel/s is 24.7% above the Tesla T4's 254.4 GTexel/s. The Geekbench Metal score of 107,342 versus the Tesla T4's average of 66,733 gives the AMD card a 60.9% lead in that specific benchmark environment. The AMD card also has a higher boost clock (2479 MHz versus 1590 MHz), a higher transistor density (46.7M per mm² versus 25.0M per mm²), and a smaller die (237 mm² versus 545 mm²).

The NVIDIA Tesla T4 wins on memory capacity and bandwidth. Its 16 GB of GDDR6 is double the AMD card's 8 GB. Its memory bandwidth of 320.0 GB/s is 25% higher than the AMD card's 256.0 GB/s. It also has a wider 256-bit memory bus versus the AMD card's 128-bit bus. The Tesla T4 has more shading units (2560 versus 2048), more texture units (160 versus 128), more ray tracing cores (40 versus 32), and 320 tensor cores where the AMD card has none. The Tesla T4 draws less power (70 W versus 120 W), requires a lower suggested PSU (250 W versus 300 W), and fits in a single slot rather than dual. Its 168 mm length is compact for a server card, and it needs no external power connectors.

The benchmark data shows a clear split in use cases. The AMD card is built for raw graphics and compute performance in a Mac-oriented environment, given its Apple MPX bus interface and its strong Metal benchmark result. The NVIDIA card is positioned for server inference and general compute, given its tensor cores, lower power draw, PCIe form factor, and its OpenCL and Vulkan benchmark scores.

The Verdict

The data supports different choices depending on the workload. For applications that rely on Metal compute on Apple platforms, the AMD Radeon Pro W6600X is the stronger performer. Its single benchmark score of 107,342 places it in the 94th percentile of all GPUs, and it sits within 3.1% of the AMD Radeon PRO W7900, one of the fastest workstation cards in the database. The Tesla T4, by contrast, sits in the 90th percentile and its average score trails the AMD card by roughly 61%. The AMD card's higher FP32 and FP16 throughput, higher pixel and texture fill rates, and higher boost clock all point to a card that will complete compute tasks faster, assuming the software stack supports it.

For workloads that require large memory capacity, low power consumption, and tensor core acceleration, the NVIDIA Tesla T4 is the better fit. Its 16 GB memory capacity is double the AMD card's 8 GB, which matters for large models or datasets. Its 70 W TDP is 41.7% lower than the AMD card's 120 W, making it easier to deploy in dense server environments. The 320 tensor cores provide dedicated hardware for inference operations, which the AMD card simply lacks. The Tesla T4's memory bandwidth of 320.0 GB/s is also higher, which helps memory-bound workloads.

The recommended selection depends on the platform and the workload type. If the system uses Apple MPX and Metal, the AMD Radeon Pro W6600X is the clear choice. If the system uses PCIe and requires tensor operations or large memory buffers, the NVIDIA Tesla T4 is the appropriate pick. Neither card has display outputs, so both are purely compute accelerators. The AMD card is end-of-life with a launch MSRP of 699 USD; the Tesla T4 is also end-of-life with no launch MSRP recorded in the database.
