AMD Radeon Pro W6600M vs NVIDIA GeForce RTX 4070 Ti Comparison

FAQ

Q: Which GPU has the higher compute benchmark score?

A: The NVIDIA GeForce RTX 4070 Ti dominates compute workloads. In Geekbench OpenCL, it scores 176,953 versus 56,140 for the AMD Radeon Pro W6600M, a delta of -68.3% for the AMD part. In Geekbench Vulkan, the NVIDIA card scores 213,808 versus 67,652, a -68.4% difference.

Q: How do these two cards rank among all GPUs in the database?

A: The AMD Radeon Pro W6600M sits at the 89th percentile of all GPUs, while the NVIDIA GeForce RTX 4070 Ti sits at the 84th percentile. Despite the NVIDIA card’s much higher raw scores, the AMD part’s average benchmark score of 61,896 places it above the RTX 4070 Ti’s average of 44,795, because the NVIDIA card’s average is pulled down by a broader set of tests including older DirectX and Passmark workloads.

Q: What is the closest rival to each card according to the database?

A: For the AMD Radeon Pro W6600M, the closest rival is the AMD Radeon 8050S with an average score of 62,108, just 0.3% higher. For the NVIDIA GeForce RTX 4070 Ti, the closest rival is the NVIDIA GeForce RTX 5090 Mobile with an average score of 45,152, which is 0.8% higher.

Q: What is the difference in memory bandwidth between the two?

A: The NVIDIA GeForce RTX 4070 Ti has 504.2 GB/s of bandwidth from 12 GB of GDDR6X on a 192-bit bus. The AMD Radeon Pro W6600M has 224.0 GB/s from 8 GB of GDDR6 on a 128-bit bus. The NVIDIA card’s bandwidth is more than double.

Q: Which card requires more power connectors?

A: The NVIDIA GeForce RTX 4070 Ti uses a single 16-pin power connector and has a suggested PSU of 600 W, with a TDP of 285 W. The AMD Radeon Pro W6600M has no power connectors (it is an IGP-style mobile part) and carries a 90 W TDP.

Q: Are these cards still in production?

A: Both are end-of-life. The AMD Radeon Pro W6600M was released on June 7, 2021, and the NVIDIA GeForce RTX 4070 Ti on January 2, 2023.

Architecture Differences

The AMD Radeon Pro W6600M is built on the Navi 23 chip using RDNA 2.0 architecture, fabricated on a 7 nm process at TSMC. The NVIDIA GeForce RTX 4070 Ti uses the AD104 chip with Ada Lovelace architecture, fabricated on a 5 nm process, also at TSMC. The process shrink is substantial: the AMD part packs 11,060 million transistors into a 237 mm² die, yielding a transistor density of 46.7 million per mm². The NVIDIA chip holds 35,800 million transistors on a 294 mm² die, for a density of 121.8 million per mm², nearly three times higher.

The shader configuration differs dramatically. AMD provides 1,792 shading units, 112 texture mapping units, and 64 raster operation pipelines. NVIDIA provides 7,680 shading units, 240 TMUs, and 80 ROPs. The RT core counts also diverge: AMD has 28 ray tracing cores, while NVIDIA has 60 RT cores. NVIDIA additionally includes 240 tensor cores; the AMD part has no tensor cores listed.

Raw throughput figures show the NVIDIA card’s advantage. The RTX 4070 Ti achieves 40.09 TFLOPS FP32 and 40.09 TFLOPS FP16 (1:1 ratio). The Radeon Pro W6600M reaches 7.290 TFLOPS FP32 and 14.58 TFLOPS FP16 (2:1 ratio). Pixel rate favors NVIDIA at 208.8 GPixel/s versus 130.2 GPixel/s, and texture rate favors NVIDIA at 626.4 GTexel/s versus 227.8 GTexel/s.

The memory subsystems reflect different design goals. AMD uses 8 GB of GDDR6 at 14 Gbps effective, while NVIDIA uses 12 GB of GDDR6X at 21 Gbps effective. The bus widths are 128-bit for AMD and 192-bit for NVIDIA. Both support PCIe 4.0 x16. API support is identical: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

Where Each One Wins

The AMD Radeon Pro W6600M wins on efficiency and form factor. Its 90 W TDP is one-third of the NVIDIA card’s 285 W, and it requires no external power connectors. The IGP slot width makes it suitable for compact mobile workstations where space and thermal headroom are tight. Its 89th percentile ranking across all GPUs indicates that, relative to the entire database, it performs above the NVIDIA card’s 84th percentile, despite lower absolute scores. The AMD part’s average benchmark score of 61,896 also exceeds the NVIDIA card’s 44,795, meaning that in the aggregate of recorded tests, the AMD part delivers more consistent results across a wide range of workloads.

The NVIDIA GeForce RTX 4070 Ti wins decisively on raw performance in the two head-to-head tests available. Its Geekbench OpenCL score of 176,953 is more than triple the AMD part’s 56,140. Its Geekbench Vulkan score of 213,808 is more than triple the AMD part’s 67,652. The NVIDIA card also provides far more memory (12 GB versus 8 GB), higher bandwidth (504.2 GB/s versus 224.0 GB/s), and a much wider shader array. For compute-heavy tasks such as rendering, simulation, or machine learning inference that leverage tensor cores, the NVIDIA card is the clear choice.

The specification sheet shows a clear split: the AMD part is a low-power mobile solution optimized for battery life and thermal constraints, while the NVIDIA card is a dual-slot desktop part designed for maximum throughput. The RTX 4070 Ti has a launch MSRP of 799 USD, while the AMD part has no listed MSRP. The NVIDIA card’s predecessor is GeForce 30 and successor is GeForce 50, while the AMD part’s predecessor is FirePro Mobile.

Head-to-Head Benchmarks

The database contains two direct benchmark comparisons between these GPUs, both in Geekbench workloads. The NVIDIA GeForce RTX 4070 Ti wins both, and by a wide margin.

In Geekbench OpenCL, the RTX 4070 Ti scores 176,953 against the Radeon Pro W6600M’s 56,140. The delta percentage is -68.3% from the AMD card’s perspective, meaning the AMD part trails by more than two-thirds. This test measures raw compute throughput across a variety of parallel workloads, and the NVIDIA card’s 7,680 shading units versus 1,792 give it a decisive advantage in raw execution width.

In Geekbench Vulkan, the RTX 4070 Ti scores 213,808 against the Radeon Pro W6600M’s 67,652. The delta is -68.4%. Vulkan tests exercise both graphics and compute paths, and the NVIDIA card’s higher boost clock of 2610 MHz versus 2034 MHz, combined with its larger memory bandwidth, contributes to the result.

The RTX 4070 Ti’s nearest rivals in the database include the NVIDIA GeForce RTX 5090 Mobile at 45,152 average score (-0.8% delta), the NVIDIA RTX A6000 at 44,075 (+1.6% delta), and the Intel Arc A730M at 45,592 (-1.7% delta). The Radeon Pro W6600M’s nearest rivals include the AMD Radeon 8050S at 62,108 (-0.3% delta), the NVIDIA GeForce RTX 4090 at 60,347 (+2.6% delta), and the Intel Arc Pro A60 at 60,326 (+2.6% delta).

The average benchmark scores tell a complementary story. The AMD part averages 61,896 across its two recorded tests, while the NVIDIA part averages 44,795 across its ten recorded tests. The NVIDIA card’s average is depressed by its Passmark DirectX 9 score of 352, Passmark DirectX 10 score of 187, and Passmark DirectX 11 score of 288, which are legacy workloads where the card does not shine. The AMD part has no such legacy scores in the database, so its average reflects only modern compute workloads.

The head-to-head tests confirm that for modern compute and graphics APIs, the RTX 4070 Ti is in a different performance class. The Radeon Pro W6600M remains competitive in its niche of low-power mobile workstations, but the data shows a clear performance hierarchy: NVIDIA wins both direct comparisons with margins exceeding 68%.
