AMD Radeon RX 6700 XT vs NVIDIA RTX PRO 4500 Blackwell Comparison

Head-to-Head Benchmarks

The benchmark data shows a decisive and consistent victory for the NVIDIA RTX PRO 4500 Blackwell across every recorded test. Out of nine head-to-head comparisons, the NVIDIA card wins all nine, with no test favoring the AMD Radeon RX 6700 XT. The most dramatic gap appears in the 3DMark Steel Nomad DX12 test, where the RTX PRO 4500 scores 7025 against 2435 for the RX 6700 XT, a delta of 188.5%. This is not a marginal lead; it is a near-tripling of the frame throughput in a modern DirectX 12 workload.

The Geekbench Vulkan results tell a similar story, with the NVIDIA card posting 221768 points versus 93500 for the AMD card, a 137.2% advantage. This indicates that the Blackwell architecture's Vulkan driver stack and hardware scheduling provide a substantial uplift in compute-heavy scenarios. The PassMark GPU Compute test reinforces this trend: the RTX PRO 4500 scores 19255, while the RX 6700 XT manages 9336, a 106.2% difference. Compute workloads, which often scale with raw shader throughput and memory bandwidth, clearly favor the NVIDIA solution.

In the DirectX 11 and DirectX 10 legacy tests, the lead narrows but remains substantial. PassMark DirectX 11 shows 320 for the RTX PRO 4500 versus 173 for the RX 6700 XT, a 85% delta. DirectX 10 shows 204 versus 124, a 64.5% delta. Even the older DirectX 9 test, which often favors architectures with high fill rates, sees the NVIDIA card ahead at 397 versus 242, a 64% delta. The PassMark G3D overall score, which aggregates many gaming and graphics workloads, lands at 33360 for the NVIDIA card versus 19786 for the AMD card, a 68.6% lead.

The 2D performance gap, while smaller in percentage terms, is still notable. PassMark G2D shows 1336 for the RTX PRO 4500 against 951 for the RX 6700 XT, a 40.5% delta. This suggests the NVIDIA card has a faster display output pipeline, which matters for workstation tasks involving heavy UI redraws or multi-monitor setups. Across all nine tests, the smallest win for the NVIDIA card is 40.5%, and the largest is 188.5%. The data shows no scenario where the AMD card comes within even a third of the NVIDIA card's performance.

Looking at the broader database context, the RTX PRO 4500 sits at the 76th percentile among all GPUs, with an average benchmark score of 31532. Its nearest rivals in the database are the NVIDIA TITAN RTX at 31676 (a -0.5% delta), the Intel Arc Pro A30M at 31894 (-1.1%), and the NVIDIA GRID M60-1Q at 31220 (+1%). The RX 6700 XT, by contrast, holds the 72nd percentile with an average score of 27425. Its nearest rival is the NVIDIA GeForce RTX 4070 Mobile at 27435 (a 0% delta), with the NVIDIA RTX PRO 4000 Blackwell at 27135 (+1.1%). While both cards rank in the upper quartile, the RTX PRO 4500's average score is roughly 15% higher than the RX 6700 XT's, which aligns with the head-to-head results.

Architecture Differences

The two cards represent fundamentally different design philosophies and manufacturing generations. The NVIDIA RTX PRO 4500 Blackwell is built on the GB203 chip using TSMC's 5 nm process, while the AMD Radeon RX 6700 XT uses the Navi 22 chip on a 7 nm process. This process difference explains much of the performance gap: the 5 nm node allows for 45,600 million transistors packed into a 378 mm² die, yielding a transistor density of 120.6 million per square millimeter. The AMD card, despite having a similar die size at 335 mm², contains only 17,200 million transistors, resulting in a density of 51.3 million per square millimeter. The NVIDIA card has over 2.6 times the transistor count in a die that is only 43 mm² larger.

This transistor budget translates into a massive difference in execution resources. The RTX PRO 4500 features 10496 shading units, 328 texture mapping units, and 112 render output units. The RX 6700 XT has 2560 shading units, 160 TMUs, and 64 ROPs. The NVIDIA card has roughly four times the shader count and double the TMUs and ROPs. Ray tracing hardware also differs: the RTX PRO 4500 has 82 RT cores, while the RX 6700 XT has 40 RT cores. Additionally, the NVIDIA card includes 328 tensor cores, which the AMD card lacks entirely; the RX 6700 XT reports no tensor core count in the database.

Memory architecture diverges sharply as well. The RTX PRO 4500 comes with 32 GB of GDDR7 memory on a 256-bit bus, delivering 896.0 GB/s of bandwidth. The RX 6700 XT has 12 GB of GDDR6 memory on a 192-bit bus, providing 384.0 GB/s. The NVIDIA card offers nearly 2.7 times the memory capacity and 2.3 times the bandwidth. This makes the RTX PRO 4500 far better suited for large datasets, high-resolution textures, and AI inference workloads that require substantial VRAM. The memory clock rates reflect the newer standard: the GDDR7 runs at 1750 MHz base with 28 Gbps effective, while the GDDR6 runs at 2000 MHz with 16 Gbps effective.

Clock speeds tell a different story, as the AMD card runs at higher frequencies. The RX 6700 XT has a base clock of 2321 MHz, a game clock of 2424 MHz, and a boost clock of 2581 MHz. The RTX PRO 4500 has a base clock of 1635 MHz and a boost of 2407 MHz. Despite the lower clock speeds, the NVIDIA card's massive shader count and wider memory bus produce far higher throughput. The FP32 compute rating is 50.53 TFLOPS for the NVIDIA card versus 13.21 TFLOPS for the AMD card. The FP16 figures are more nuanced: the NVIDIA card achieves 50.53 TFLOPS at a 1:1 ratio, while the AMD card achieves 26.43 TFLOPS at a 2:1 ratio, meaning the AMD card's FP16 is half its FP32 rate. The RTX PRO 4500's pixel rate is 269.6 GPixel/s versus 165.2 GPixel/s for the RX 6700 XT, and its texture rate is 789.5 GTexel/s versus 413.0 GTexel/s.

Power and interface differences are also recorded. The RTX PRO 4500 has a TDP of 200 W and uses a single 16-pin power connector. The RX 6700 XT has a higher TDP of 230 W and uses a 6-pin plus 8-pin combination. Both cards suggest a 550 W power supply. The bus interface differs: the NVIDIA card uses PCIe 5.0 x16, while the AMD card uses PCIe 4.0 x16. Display outputs also vary, with the RTX PRO 4500 offering four DisplayPort 2.1b outputs, while the RX 6700 XT provides one HDMI 2.1 and three DisplayPort 1.4a outputs. Both cards are dual-slot, measure 267 mm in length, and are nearly identical in height (111 mm for NVIDIA, 110 mm for AMD) and width (both 40 mm).

The Verdict

The data points to a single conclusion: the NVIDIA RTX PRO 4500 Blackwell outperforms the AMD Radeon RX 6700 XT in every recorded benchmark, with margins ranging from 40.5% to 188.5%. The average benchmark score for the NVIDIA card is 31532 against 27425 for the AMD card, placing the former at the 76th percentile and the latter at the 72nd percentile among all GPUs. For any workload measured in this database, the RTX PRO 4500 is the faster card.

The RTX PRO 4500 is the clear choice for users who need maximum compute throughput, large memory capacity, or ray tracing and tensor core support. Its 32 GB of GDDR7 memory, 896.0 GB/s of bandwidth, and 50.53 TFLOPS of FP32 performance make it suited for AI model training, large-scale rendering, and scientific simulation. The inclusion of 328 tensor cores further extends its reach into deep learning workloads, where the RX 6700 XT has no corresponding hardware.

The RX 6700 XT, while older and slower in every test, still holds a place for specific use cases. Its higher base and boost clocks (2321 MHz and 2581 MHz) suggest it can handle lighter tasks with lower latency, and its 230 W TDP, while higher than the NVIDIA card's 200 W, is still manageable with a 550 W power supply. However, the database shows that the RX 6700 XT's nearest rivals include the NVIDIA GeForce RTX 3090 at a -0.5% delta, meaning it sits in a performance tier far below the RTX PRO 4500. The RX 6700 XT is also marked as end-of-life in production status, while the RTX PRO 4500 is active.

For buyers prioritizing raw performance, the RTX PRO 4500 is the only rational choice based on the data. For those with legacy software that favors higher clock speeds or who require the specific display output configuration of one HDMI 2.1 and three DisplayPort 1.4a, the RX 6700 XT remains a functional option, but it cannot match the Blackwell card in any benchmark recorded here. The verdict is unambiguous: the NVIDIA RTX PRO 4500 Blackwell dominates the AMD Radeon RX 6700 XT across the board.
