NVIDIA Quadro RTX 8000 vs NVIDIA RTX PRO 4500 Blackwell Comparison

Where Each One Wins

The recorded data shows a clean sweep for the NVIDIA RTX PRO 4500 Blackwell across every shared benchmark test. Out of eight head-to-head comparisons, the RTX PRO 4500 Blackwell takes all eight wins, leaving the Quadro RTX 8000 without a single victory in the measured categories. This is not a case of one card excelling in some workloads while the other reclaims ground elsewhere; the newer Blackwell part dominates uniformly in the database’s tested scenarios.

The RTX PRO 4500 Blackwell’s strongest relative advantage appears in compute-heavy and legacy graphics workloads. Its Passmark GPU Compute score of 19,255 is 92.7% higher than the Quadro RTX 8000’s 9,992, making that the largest delta between the two in any test. Similarly, the DirectX 9 result shows an 88.2% gap, with the RTX PRO 4500 Blackwell scoring 397 against the Quadro RTX 8000’s 211. These results indicate that the Blackwell card does not merely scale up with modern APIs; it also improves performance in older DirectX paths, which can matter for compatibility testing and legacy application support.

In pure 3D rendering, the Passmark G3D score of 33,360 for the RTX PRO 4500 Blackwell versus 19,799 for the Quadro RTX 8000 represents a 68.5% advantage. The Vulkan benchmark tells a similar story: 221,768 for the Blackwell card versus 122,637 for the Turing card, an 80.8% lead. For users running Vulkan-based visualization or game engines, the recorded data suggests the newer card offers substantially higher throughput.

The Quadro RTX 8000 does retain one structural advantage in memory capacity: 48 GB versus 32 GB. That is not reflected in any of the benchmark wins, but it does mean the older card can hold larger datasets entirely in VRAM before spilling to system memory. However, the bandwidth situation inverts: the RTX PRO 4500 Blackwell delivers 896.0 GB/s against the Quadro RTX 8000’s 672.0 GB/s, a 33% bandwidth advantage for the newer part. So while the Quadro RTX 8000 can fit more data, the Blackwell card can move that data faster once resident.

The average benchmark score in the database reinforces the split: the RTX PRO 4500 Blackwell averages 31,532 across all recorded tests, while the Quadro RTX 8000 averages 28,421. That places the Blackwell part at the 76th percentile of all GPUs in the database, versus the 74th percentile for the Quadro RTX 8000. The percentile difference is modest, but the average score gap of roughly 11% points to a consistent overall performance edge rather than a single outlier result.

Architecture Differences

The two cards come from different architectural generations and process nodes. The RTX PRO 4500 Blackwell uses the GB203 chip on a 5 nm TSMC process, while the Quadro RTX 8000 uses the TU102 chip on a 12 nm TSMC process. That node difference is stark: 5 nm versus 12 nm, which directly affects transistor density. The GB203 packs 45,600 million transistors into a 378 mm² die, yielding a density of 120.6 million transistors per square millimeter. The TU102, by contrast, has 18,600 million transistors spread across a much larger 754 mm² die, giving a density of just 24.7 million per square millimeter. The Blackwell chip is physically smaller yet contains more than twice the transistor count.

The shading pipeline also differs significantly. The RTX PRO 4500 Blackwell has 10,496 shading units, 328 TMUs, and 112 ROPs. The Quadro RTX 8000 has 4,608 shading units, 288 TMUs, and 96 ROPs. The Blackwell card more than doubles the shading unit count, while the TMU and ROP counts are closer, suggesting the newer design leans heavily on compute throughput rather than raw texture or pixel output. The Blackwell card’s FP32 throughput is 50.53 TFLOPS, compared to 16.31 TFLOPS for the Quadro RTX 8000, a 3.1x gap in single-precision compute.

Ray tracing and tensor hardware follow different counts as well. The RTX PRO 4500 Blackwell has 82 RT cores and 328 tensor cores. The Quadro RTX 8000 has 72 RT cores and 576 tensor cores. The older Turing card actually has more tensor cores by a wide margin, but the Blackwell architecture’s tensor cores are from a newer generation and operate within a higher-clock design. The FP16 throughput tells the story: the RTX PRO 4500 Blackwell achieves 50.53 TFLOPS with a 1:1 ratio to FP32, while the Quadro RTX 8000 reaches 32.62 TFLOPS at a 2:1 ratio. The Blackwell part sustains its FP16 rate without halving the FP32 rate.

Memory architecture differs in type and bus width. The RTX PRO 4500 Blackwell uses 32 GB of GDDR7 on a 256-bit bus, while the Quadro RTX 8000 uses 48 GB of GDDR6 on a 384-bit bus. The Blackwell card’s effective memory speed is 28 Gbps, versus 14 Gbps for the Quadro RTX 8000. That doubling of effective speed, combined with the narrower bus, still yields higher total bandwidth for the newer card. Clock speeds also favor Blackwell: 1635 MHz base and 2407 MHz boost versus 1395 MHz base and 1770 MHz boost for Turing.

The power and interface situation differs as well. The RTX PRO 4500 Blackwell has a 200 W TDP and uses a single 16-pin power connector, with a suggested 550 W PSU. The Quadro RTX 8000 has a 260 W TDP, uses one 6-pin plus one 8-pin connector, and suggests a 600 W PSU. The Blackwell card delivers more performance at a lower power envelope. The bus interface advances from PCIe 3.0 x16 on the Turing card to PCIe 5.0 x16 on the Blackwell card, which doubles the available host link bandwidth for data transfers. Display outputs also change: the RTX PRO 4500 Blackwell offers 4x DisplayPort 2.1b, while the Quadro RTX 8000 offers 4x DisplayPort 1.4a plus one USB Type-C.

Head-to-Head Benchmarks

The largest single-test win for the RTX PRO 4500 Blackwell comes in Passmark GPU Compute, where it scores 19,255 against the Quadro RTX 8000’s 9,992, a 92.7% delta. This test measures general-purpose compute performance, and the gap aligns with the FP32 throughput difference between the two cards. For workloads like simulation, rendering on GPU, or data processing, the recorded numbers indicate that the Blackwell card is nearly twice as fast.

The Vulkan benchmark shows an 80.8% lead: 221,768 versus 122,637. Vulkan is a low-overhead API used in both professional visualization and modern game engines, so this result suggests that the RTX PRO 4500 Blackwell will feel substantially faster in real-time graphics workloads that rely on explicit command queues. The DirectX 9 test is the second-largest percentage gap at 88.2%, with scores of 397 and 211. That older API still appears in some industrial and CAD software, so the Blackwell card’s strong showing there is notable.

In DirectX 11, the RTX PRO 4500 Blackwell scores 320 versus 188, a 70.2% advantage. DirectX 12 shows a more modest but still decisive 50.6% gap: 119 versus 79. The DirectX 10 test yields 204 versus 137, a 48.9% lead. The 2D graphics test, Passmark G2D, shows 1,336 versus 866, a 54.3% delta, which matters for desktop compositing and 2D CAD panning. The 3D test, Passmark G3D, shows 33,360 versus 19,799, a 68.5% gap.

The Quadro RTX 8000 does have one benchmark in the database that the RTX PRO 4500 Blackwell does not share: Geekbench OpenCL, where it scores 101,883. That result is not comparable to anything on the Blackwell side in the recorded data, so it cannot be used for a direct head-to-head. The only overlapping non-DirectX benchmark, Geekbench Vulkan, is listed above and favors the Blackwell card by a wide margin.
