Q: Which GPU has more shading units?

A: The NVIDIA TITAN V CEO Edition has 5,120 shading units, compared to 640 on the AMD Radeon Pro 450. That is an 8x difference in raw shader count, yet the average benchmark scores do not reflect this proportional advantage, which raises immediate questions about the benchmark suite's weighting.

Q: How do the memory subsystems compare?

A: The Radeon Pro 450 uses 2 GB of GDDR5 on a 128-bit bus, delivering 81.28 GB/s of bandwidth. The TITAN V CEO Edition uses 32 GB of HBM2 on a 4096-bit bus, delivering 868.4 GB/s, more than 10 times the bandwidth and 16 times the capacity.

Q: What is the transistor and die size difference?

A: The AMD chip, Baffin, packs 3,000 million transistors on a 123 mm² die at 14 nm. The NVIDIA GV100 die is 815 mm² with 21,100 million transistors at 12 nm. Despite being nearly 7x larger in die area, the TITAN V's average score is lower.

Q: Which GPU supports newer API versions?

A: The TITAN V CEO Edition supports DirectX 12 (12_1) and Vulkan 1.4, while the Radeon Pro 450 supports DirectX 12 (12_0) and Vulkan 1.3. Both support OpenGL 4.6.

Q: What is the TDP difference?

A: The Radeon Pro 450 is rated at 35 W, while the TITAN V CEO Edition is rated at 250 W, a 7x increase in power draw. The NVIDIA card also requires a 600 W suggested PSU and dual-slot cooling, whereas the AMD part is an MXM module.

Architecture Differences

The two GPUs come from opposite ends of the design spectrum. The AMD Radeon Pro 450 uses the Baffin chip built on GCN 4.0 architecture, manufactured by GlobalFoundries on a 14 nm process. It is a compact design at 123 mm², integrating 3,000 million transistors for a density of 24.4M per mm². The NVIDIA TITAN V CEO Edition uses the GV100 chip on Volta architecture, built by TSMC on a 12 nm process. Its die measures 815 mm², holding 21,100 million transistors, yielding a slightly higher density of 25.9M per mm². The TITAN V is physically enormous in comparison, yet both share end-of-life production status.

Core configuration diverges sharply. The Radeon Pro 450 has 640 shading units, 40 texture mapping units, and 16 ROPs. The TITAN V CEO Edition has 5,120 shading units, 320 TMUs, and 128 ROPs. The NVIDIA part also includes 640 tensor cores, a feature entirely absent from the AMD GPU. Neither card has dedicated ray tracing cores, so that particular feature set is not a differentiator here.

Memory architecture is another fundamental split. The Radeon Pro 450 uses 2 GB of GDDR5 on a 128-bit bus, achieving 81.28 GB/s of bandwidth. The TITAN V CEO Edition uses 32 GB of HBM2 on a 4096-bit bus, achieving 868.4 GB/s. The memory clock values also differ: the AMD memory runs at 1270 MHz with 5.1 Gbps effective, while the NVIDIA memory runs at 848 MHz with 1696 Mbps effective, though the bus width difference overwhelms that clock disadvantage.

Compute capabilities show the NVIDIA card's theoretical dominance. The TITAN V delivers 14.90 TFLOPS FP32 and 29.80 TFLOPS FP16 with a 2:1 ratio, while the Radeon Pro 450 delivers 1,024.0 GFLOPS FP32 and 1,024.0 GFLOPS FP16 at a 1:1 ratio. Pixel rate favors NVIDIA at 186.2 GPixel/s versus 12.80 GPixel/s, and texture rate favors NVIDIA at 465.6 GTexel/s versus 32.00 GTexel/s. These are massive theoretical gaps, making the benchmark results even more puzzling.

Head-to-Head Benchmarks

The database records no direct head-to-head benchmark entries between these two cards, so the comparison relies on their individual test suites. The Radeon Pro 450 was evaluated with Geekbench Metal, OpenCL, and Vulkan tests, scoring 12,893, 9,002, and 10,518 respectively. The TITAN V CEO Edition was evaluated with Passmark G2D and G3D tests, scoring 1,086 and 16,988 respectively. The different test suites make direct apples-to-apples comparison difficult, but the average scores still tell a story.

The Radeon Pro 450's average benchmark score of 10,804 places it near the NVIDIA Quadro K2200, which averages 10,761, a delta of 0.4% in AMD's favor. It also sits ahead of the NVIDIA GeForce GTX 560 Ti, which scores 10,690, a 1.1% delta, and the AMD Radeon RX 6600S, which scores 10,629, a 1.7% delta. The closest rival on the other side is the NVIDIA GeForce MX350, which scores 10,883, putting AMD 0.7% behind that card. This is a tight cluster of results, suggesting the Radeon Pro 450 performs like a midrange part of its era.

The TITAN V CEO Edition's average of 9,037 places it near the NVIDIA GeForce GTX 560, which scores 9,058, a delta of 0.2% in NVIDIA's favor. It also sits close to the NVIDIA GeForce GTX 660, which scores 9,022, a 0.2% delta, and the AMD Radeon 550X, which scores 8,918, a 1.3% delta. The AMD Radeon 890M scores 9,210, putting it 1.9% ahead of the TITAN V. These rivals are all older or lower-tier parts, which suggests the TITAN V's Passmark G3D score of 16,988 is being dragged down by its very low G2D score of 1,086 in the average.

The percentile rankings add another layer. The Radeon Pro 450 sits at the 49th percentile of all GPUs, while the TITAN V CEO Edition sits at the 45th percentile. The AMD part is therefore ranked slightly higher in the overall distribution, despite the NVIDIA card's vastly superior specifications. This is a case where theoretical compute power does not translate to the benchmark scores recorded in this database, possibly due to driver maturity, workload selection, or the specific tests used for each GPU.

Specification Differences

The recorded data shows differences in nearly every major specification category. Process node: 14 nm for AMD versus 12 nm for NVIDIA. Foundry: GlobalFoundries versus TSMC. Transistors: 3,000 million versus 21,100 million. Die size: 123 mm² versus 815 mm². Transistor density: 24.4M per mm² versus 25.9M per mm².

Clock speeds differ in presentation: the Radeon Pro 450 lists no base or boost clock in the database, while the TITAN V lists 1200 MHz base and 1455 MHz boost. Memory clocks are 1270 MHz with 5.1 Gbps effective for AMD, and 848 MHz with 1696 Mbps effective for NVIDIA. Memory size is 2 GB versus 32 GB, type is GDDR5 versus HBM2, bus width is 128-bit versus 4096-bit, and bandwidth is 81.28 GB/s versus 868.4 GB/s.

Compute resources differ as noted: 640 versus 5,120 shading units, 40 versus 320 TMUs, 16 versus 128 ROPs, and 0 versus 640 tensor cores. Pixel rate is 12.80 GPixel/s versus 186.2 GPixel/s. Texture rate is 32.00 GTexel/s versus 465.6 GTexel/s. FP32 is 1,024.0 GFLOPS versus 14.90 TFLOPS. FP16 is 1,024.0 GFLOPS versus 29.80 TFLOPS.

Power and physical specs also diverge: TDP is 35 W versus 250 W. Slot width is MXM Module versus Dual-slot. Power connectors are absent on the AMD card versus 1x 6-pin plus 1x 8-pin on the NVIDIA card. Suggested PSU is not listed for AMD, but 600 W for NVIDIA. Bus interface is PCIe 3.0 x8 versus PCIe 3.0 x16. Display outputs are portable-device dependent for AMD, versus 1x HDMI 2.0 and 3x DisplayPort 1.4a for NVIDIA. Dimensions are not listed for AMD, but the TITAN V measures 267 mm in length, 112 mm in height, and 40 mm in width. Release dates are 2016-10-29 for AMD and 2018-06-20 for NVIDIA. The TITAN V lists a predecessor of GeForce 900 and successor of GeForce 20; the Radeon Pro 450 lists no predecessor or successor.

Where Each One Wins

The AMD Radeon Pro 450 wins in the aggregate benchmark metric. Its average score of 10,804 beats the TITAN V CEO Edition's 9,037 by roughly 19.5%. It also holds a higher percentile ranking at 49 versus 45. In its individual Geekbench tests, the Metal score of 12,893 and Vulkan score of 10,518 are particularly strong. The OpenCL score of 9,002 is lower but still contributes to a solid average. The AMD card also wins decisively in power efficiency, with a 35 W TDP versus 250 W, and it occupies a compact MXM form factor, making it suitable for portable or space-constrained systems.

The NVIDIA TITAN V CEO Edition wins in raw specification comparisons. Its Passmark G3D score of 16,988 is far higher than any single AMD benchmark score recorded. It dominates in memory capacity, bandwidth, shading units, texture units, ROPs, and compute throughput. The 32 GB HBM2 memory pool and 868.4 GB/s bandwidth make it a clear choice for workloads that demand large datasets and high memory throughput. The tensor cores provide hardware acceleration for AI inference and training workloads that the AMD part cannot match. Its Vulkan 1.4 support and DirectX 12_1 API level are also ahead of the AMD card's Vulkan 1.3 and DirectX 12_0.

The data suggests a split between synthetic benchmark averages and specification-driven workloads. In the database's averaged score, AMD wins. In theoretical peak throughput, NVIDIA wins by factors of 10 or more. The G2D score of 1,086 for the TITAN V is notably low, and it pulls down the NVIDIA average considerably when combined with the G3D score. This indicates that the TITAN V's weakness in 2D tests may not reflect its 3D or compute strengths.

The Verdict

The recorded data presents a contradictory picture. The AMD Radeon Pro 450 has the higher average benchmark score and percentile ranking, but the NVIDIA TITAN V CEO Edition has overwhelmingly superior specifications. A user choosing strictly by the database's average score would pick the AMD part, especially for power-sensitive or portable applications where the 35 W TDP and MXM form factor are clear advantages. The Radeon Pro 450 also offers strong Geekbench Metal and Vulkan results, which may indicate solid performance in macOS or Vulkan-based environments.

A user choosing strictly by raw capability would pick the TITAN V CEO Edition. The 32 GB HBM2 memory, 868.4 GB/s bandwidth, 5,120 shading units, and 640 tensor cores make it the only option for large-scale compute, deep learning, or memory-intensive tasks. Its Passmark G3D score of 16,988 confirms strong 3D rendering performance, even if the G2D score drags down the average. The dual-slot cooling, 250 W TDP, and 600 W suggested PSU indicate a desktop-only part with substantial power requirements.

The benchmark results imply that the two GPUs serve different purposes and were tested with different suites. The AMD card's wins in Metal, OpenCL, and Vulkan reflect a mobile-oriented, API-diverse profile. The NVIDIA card's wins in Passmark reflect a desktop-oriented, raw-throughput profile. Neither card is a clear all-around winner in the database. The choice depends on whether the user prioritizes the averaged benchmark score and efficiency, or the specification sheet and theoretical compute ceiling. The data supports both conclusions, depending on which metric matters more.
