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

Head-to-Head Benchmarks

The database contains only one recorded benchmark result for these two server-class accelerators, and it belongs to the NVIDIA RTX PRO 6000 Blackwell Server. In the 3DMark Steel Nomad DX12 test, the RTX PRO 6000 scores 5996 points. This places it in the 34th percentile among all GPUs in the database. The RTX PRO 4500 Blackwell Server has no recorded benchmark scores, so direct performance comparisons between the two cannot be made from measured data alone.

The RTX PRO 6000's single benchmark result sits within a tight cluster of rival scores. The NVIDIA GeForce GTX 770M averages 6000 points, a delta of -0.1% relative to the RTX PRO 6000. The AMD Radeon RX 6400 also averages 6001 points, again a -0.1% delta. On the other side, the AMD FirePro W4100 averages 5987 points, which is 0.2% behind the RTX PRO 6000, and the NVIDIA Quadro K4000M averages 5986 points, also 0.2% behind. These deltas are all within a fraction of a percent, indicating that the RTX PRO 6000's measured performance in this single DX12 workload is effectively equivalent to several much older or lower-tier consumer and workstation cards.

What the benchmark data does not show is any head-to-head comparison between the RTX PRO 4500 and the RTX PRO 6000. The head-to-head benchmark list is empty, and neither card has multiple benchmark entries. The RTX PRO 4500 has zero wins in the database, and the RTX PRO 6000 also has zero wins. This means the recorded data cannot confirm which card is faster in any specific workload. The only measured result belongs to the RTX PRO 6000, and it indicates performance roughly on par with the GTX 770M and RX 6400 in that particular test, despite the massive architectural differences between those products.

The absence of a recorded score for the RTX PRO 4500 is notable. The database assigns it a 50th percentile ranking among all GPUs, but this ranking is derived from no measured benchmark data, as its average benchmark score is zero. In contrast, the RTX PRO 6000's 34th percentile ranking comes from its single 5996-point result. Neither card has a launch MSRP listed in the records, so no pricing information is available for either product.

Where Each One Wins

From the data available, the RTX PRO 6000 Blackwell Server is the only card with a confirmed benchmark result. It delivers a 5996-point score in 3DMark Steel Nomad DX12, which is the sole recorded performance metric for either product. The RTX PRO 4500 has no wins in the database, and the RTX PRO 6000 has no wins either, since the head-to-head comparison list is empty.

Looking at the broader specifications, the RTX PRO 6000 holds clear advantages in every compute category. Its FP32 throughput is listed at 126.0 TFLOPS, while the RTX PRO 4500 delivers 50.70 TFLOPS. FP16 performance follows the same 1:1 ratio for both cards, with the RTX PRO 6000 again at 126.0 TFLOPS and the RTX PRO 4500 at 50.70 TFLOPS. The texture rate for the RTX PRO 6000 is 1,968.0 GTexel/s versus 792.1 GTexel/s for the RTX PRO 4500. Pixel rate is 502.5 GPixel/s versus 270.5 GPixel/s. These are substantial margins, roughly 2.5x in FP32 and FP16, approximately 2.5x in texture rate, and about 1.9x in pixel rate.

Memory capacity and bandwidth also favor the RTX PRO 6000 decisively. It carries 96 GB of GDDR7 on a 512-bit bus, yielding 1.79 TB/s of bandwidth. The RTX PRO 4500 has 32 GB of GDDR7 on a 256-bit bus, providing 800.3 GB/s. That is more than double the capacity and more than double the bandwidth. The RTX PRO 6000 also has more execution resources: 24,064 shading units versus 10,496, 752 texture mapping units versus 328, 192 ROPs versus 112, 188 ray tracing cores versus 82, and 752 tensor cores versus 328.

Clock speeds are another differentiator. The RTX PRO 6000 has a base clock of 1590 MHz and a boost clock of 2617 MHz. The RTX PRO 4500 runs at a 1215 MHz base and 2415 MHz boost. Memory clocks also differ, with the RTX PRO 6000 at 1750 MHz (28 Gbps effective) and the RTX PRO 4500 at 1563 MHz (25 Gbps effective). The RTX PRO 6000's higher clocks contribute to its higher throughput figures, though the core count difference is the dominant factor.

Power and physical design diverge as well. The RTX PRO 6000 has a TDP of 600 W and requires a dual-slot form factor with a suggested 1000 W power supply. The RTX PRO 4500 is rated at 165 W, fits in a single slot, and suggests a 450 W power supply. Both use a single 16-pin power connector and share the same physical dimensions: 267 mm length, 111 mm height, and 40 mm width. The RTX PRO 6000 includes four DisplayPort 2.1b outputs, while the RTX PRO 4500 has no display outputs at all, consistent with its server-oriented positioning.

The Verdict

The recorded data shows a clear specification hierarchy, but the benchmark evidence is minimal. The RTX PRO 6000 Blackwell Server is the only card with a measured score, and that score is 5996 points in 3DMark Steel Nomad DX12. This result places it near the GTX 770M, RX 6400, FirePro W4100, and Quadro K4000M, all within 0.2% of each other. The RTX PRO 4500 has no measured scores, so no performance conclusion can be drawn from benchmarks.

For buyers selecting between these two server accelerators, the RTX PRO 6000 offers more of everything that matters in compute-heavy workloads: double the memory capacity, more than double the bandwidth, roughly 2.5x the FP32 throughput, and significantly more shading units, tensor cores, and ray tracing cores. It also runs at higher clocks and supports four display outputs. The trade-off is a 600 W TDP and dual-slot footprint versus 165 W and single-slot for the RTX PRO 4500. The RTX PRO 4500's lower power draw and single-slot design may fit dense server chassis where power and space are constrained, but the RTX PRO 6000 is the stronger compute platform on every recorded specification.

The data does not support any claim that the RTX PRO 4500 outperforms the RTX PRO 6000 in any workload, because no benchmark results exist for the former. The RTX PRO 6000's single benchmark score, while modest relative to its specifications, is at least a measured data point. The RTX PRO 4500's 50th percentile ranking in the database is unverified by any benchmark entry.

Architecture Differences

The two accelerators share the same fundamental architecture, Blackwell 2.0, and are both built by TSMC on a 5 nm process. However, the silicon underneath is quite different. The RTX PRO 4500 uses the GB203 chip, which packs 45,600 million transistors into a 378 mm² die, yielding a transistor density of 120.6 million per square millimeter. The RTX PRO 6000 uses the GB202 chip, with 92,200 million transistors on a 750 mm² die, giving a density of 122.9 million per square millimeter. The GB202 die is nearly double the area and more than double the transistor count.

The execution resource counts scale accordingly. The RTX PRO 4500 has 10,496 shading units, 328 TMUs, 112 ROPs, 82 ray tracing cores, and 328 tensor cores. The RTX PRO 6000 has 24,064 shading units, 752 TMUs, 192 ROPs, 188 ray tracing cores, and 752 tensor cores. These figures are roughly 2.3x to 2.9x higher on the RTX PRO 6000, depending on the specific unit.

Clock behavior also differs. The RTX PRO 4500 runs at a 1215 MHz base and 2415 MHz boost, while the RTX PRO 6000 runs at a 1590 MHz base and 2617 MHz boost. Memory clocks are 1563 MHz (25 Gbps effective) for the RTX PRO 4500 and 1750 MHz (28 Gbps effective) for the RTX PRO 6000. The higher clocks on the RTX PRO 6000, combined with the larger core count, produce the throughput advantages seen in the FP32, FP16, texture, and pixel rate figures.

Memory architecture is another major split. The RTX PRO 4500 uses a 256-bit bus with 32 GB of GDDR7, delivering 800.3 GB/s. The RTX PRO 6000 uses a 512-bit bus with 96 GB of GDDR7, delivering 1.79 TB/s. The bus width difference is directly responsible for the bandwidth gap, and the capacity difference is substantial for workloads that need large model or dataset residency.

Physical and electrical designs diverge as well. The RTX PRO 4500 is a single-slot card with a 165 W TDP and a suggested 450 W power supply. The RTX PRO 6000 is a dual-slot card with a 600 W TDP and a suggested 1000 W power supply. Both share identical dimensions: 267 mm length, 111 mm height, and 40 mm width. Both use PCIe 5.0 x16 and a single 16-pin power connector. The RTX PRO 6000 includes four DisplayPort 2.1b outputs; the RTX PRO 4500 has none.

Both cards support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Both are listed as Active in production status, with the RTX PRO 6000 released on 2025-03-17 and the RTX PRO 4500 released on 2026-03-16. Both share the same predecessor, Server Hopper, and the same successor, Server Rubin. Neither card has a launch MSRP recorded in the database.
