NVIDIA RTX 6000D vs NVIDIA RTX PRO 4500 Blackwell Server Comparison

Head-to-Head Benchmarks

The benchmark database contains recorded results for the NVIDIA RTX 6000D, while the RTX PRO 4500 Blackwell Server has no benchmark entries at this time. This asymmetry limits direct numerical comparison, but the available data for the RTX 6000D provides a clear reference point.

The RTX 6000D achieves an average benchmark score of 195,964 across its recorded tests. This places it in the 98th percentile of all GPUs in the database. Its nearest rival, the NVIDIA Tesla V100S PCIe 32 GB, scores 194,415, which is 0.8% lower. The A100 SXM4 40 GB trails by 4.7% with a score of 187,147, while the RTX 5000 Ada Generation is 6.1% behind at 184,664. The A100 PCIe 80 GB is the only listed rival that outperforms it, scoring 207,124, a 5.4% advantage.

In specific tests, the RTX 6000D records a 3DMark Steel Nomad DX12 score of 3,522 and a Geekbench OpenCL score of 388,405. These results, combined with its 98th percentile ranking, indicate that the RTX 6000D sits near the top of the database hierarchy. The RTX PRO 4500 Blackwell Server, by contrast, has no recorded scores and sits at the 50th percentile with an average score of zero, which reflects the absence of measurement data rather than actual performance characteristics.

Architecture Differences

Both GPUs share the Blackwell 2.0 architecture and are fabricated on TSMC's 5 nm process. The fundamental distinction lies in their chip designs. The RTX 6000D uses the GB202 chip with 92,200 million transistors on a 750 mm² die. The RTX PRO 4500 Blackwell Server uses the smaller GB203 chip, housing 45,600 million transistors on a 378 mm² die. Transistor density is similar: 122.9M per mm² for the RTX 6000D versus 120.6M per mm² for the RTX PRO 4500.

The compute configuration diverges sharply. The RTX 6000D carries 19,968 shading units, 624 texture mapping units, 192 raster output units, 156 ray tracing cores, and 624 tensor cores. The RTX PRO 4500 Blackwell Server has 10,496 shading units, 328 TMUs, 112 ROPs, 82 RT cores, and 328 tensor cores. In every category, the RTX 6000D roughly doubles the resource count.

Clock behavior differs as well. The RTX 6000D runs at a base clock of 1992 MHz and boosts to 2430 MHz. The RTX PRO 4500 Blackwell Server has a lower base of 1215 MHz but a boost of 2415 MHz, nearly matching the RTX 6000D's peak. Memory clocks are comparable: 1560 MHz (25 Gbps effective) for the RTX 6000D versus 1563 MHz (25 Gbps effective) for the RTX PRO 4500.

The architecture generation labels differ: the RTX 6000D belongs to the Blackwell PRO W (x000) generation, while the RTX PRO 4500 Blackwell Server is part of the Server Blackwell (Bxx) generation. Both expose identical API support: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

Where Each One Wins

The RTX 6000D holds advantages in raw throughput metrics. Its pixel rate of 466.6 GPixel/s compares to 270.5 GPixel/s for the RTX PRO 4500 Blackwell Server, a 72.5% lead. Texture rate follows a similar pattern: 1,516.3 GTexel/s versus 792.1 GTexel/s. FP32 compute reaches 97.04 TFLOPS on the RTX 6000D, nearly double the 50.70 TFLOPS of the RTX PRO 4500. FP16 performance is identical at 1:1 ratios, with the same numerical values.

Memory capacity strongly favors the RTX 6000D at 84 GB of GDDR7 on a 448-bit bus, delivering 1.40 TB/s of bandwidth. The RTX PRO 4500 Blackwell Server offers 32 GB of GDDR7 on a 256-bit bus, providing 800.3 GB/s. The RTX 6000D's memory subsystem provides 75% more bandwidth and more than double the capacity.

The RTX PRO 4500 Blackwell Server wins on power efficiency and physical footprint. Its 165 W TDP is less than a third of the RTX 6000D's 600 W. It requires only a 450 W suggested power supply versus 1000 W for the RTX 6000D. The server card is single-slot, while the RTX 6000D is dual-slot. The RTX PRO 4500 measures 267 mm in length and 111 mm in height, compared to 304 mm by 137 mm for the RTX 6000D. Both share the same 40 mm width.

The Verdict

The database shows a clear performance hierarchy. The RTX 6000D sits at the 98th percentile of all GPUs with an average benchmark score of 195,964, while the RTX PRO 4500 Blackwell Server has no recorded benchmarks and a 50th percentile placeholder. The RTX 6000D leads in every compute and memory metric recorded, from FP32 throughput to texture rate to VRAM capacity.

The RTX 6000D is the choice for workloads that demand maximum compute, memory capacity, and bandwidth. Its 84 GB of GDDR7 and 1.40 TB/s bandwidth, plus 97.04 TFLOPS of FP32 performance, position it for large-scale rendering and simulation tasks. Its dual-slot design and 600 W TDP reflect its high-performance orientation.

The RTX PRO 4500 Blackwell Server targets a different profile. Its single-slot form factor, 165 W TDP, and 450 W suggested PSU make it suitable for dense server deployments where power and space are constrained. Its 32 GB of GDDR7 and 50.70 TFLOPS still offer substantial compute, but the absence of recorded benchmarks means its real-world standing cannot be quantified from the current data. The lack of display outputs confirms its headless server role.

Buyers requiring peak performance and large memory should select the RTX 6000D. Those prioritizing low power draw, single-slot density, and server-specific operation should consider the RTX PRO 4500 Blackwell Server, acknowledging that its benchmark position remains unmeasured.
