AMD Radeon RX 560 XT vs NVIDIA RTX PRO 4500 Blackwell Comparison

FAQ

Q: How do the two GPUs compare in raw compute performance?

A: The NVIDIA RTX PRO 4500 Blackwell delivers 50.53 TFLOPS of FP32 performance, which is over 11 times the 4.394 TFLOPS of the AMD Radeon RX 560 XT. This massive gap is consistent across every metric, from texture rate (789.5 GTexel/s vs 137.3 GTexel/s) to pixel rate (269.6 GPixel/s vs 39.23 GPixel/s).

Q: Are these cards in the same performance class?

A: No. The RX 560 XT sits at the 79th percentile of all GPUs, while the RTX PRO 4500 sits at the 76th percentile. Their average benchmark scores are 34,133 and 31,532 respectively, meaning the RX 560 XT actually has a slightly higher average score, despite being far older and less powerful in raw specs.

Q: What is the memory configuration difference?

A: The RX 560 XT has 4 GB of GDDR5 on a 256-bit bus with 224.0 GB/s bandwidth. The RTX PRO 4500 has 32 GB of GDDR7 on a 256-bit bus with 896.0 GB/s bandwidth. That is 8 times the capacity and 4 times the bandwidth.

Q: Do these GPUs support different PCIe standards?

A: Yes. The RX 560 XT uses PCIe 3.0 x16, while the RTX PRO 4500 uses PCIe 5.0 x16. This means the newer card has access to substantially more host interface bandwidth, which can matter for data transfer in professional workloads.

Q: Which GPU has better ray tracing support?

A: The RTX PRO 4500 Blackwell includes 82 dedicated RT cores and 328 tensor cores. The RX 560 XT has no RT cores or tensor cores listed, meaning it lacks dedicated hardware for ray tracing and AI acceleration.

Q: What is the launch timeframe difference?

A: The RX 560 XT was released on 2019-03-12 and is now end-of-life. The RTX PRO 4500 was released on 2025-03-17 and is still active. That is a six-year gap between launches.

Architecture Differences

The architectural divide here is generational and fundamental. The AMD Radeon RX 560 XT uses the Ellesmere chip built on GCN 4.0 architecture, part of the Polaris (RX 500) generation. It is fabricated on a 14 nm process at GlobalFoundries, packing 5,700 million transistors into a 232 mm² die, yielding a transistor density of 24.6 million per mm². In contrast, the NVIDIA RTX PRO 4500 Blackwell uses the GB203 chip with Blackwell 2.0 architecture from the Blackwell PRO W (x000) generation. It is built on TSMC's 5 nm process with 45,600 million transistors in a 378 mm² die, achieving a transistor density of 120.6 million per mm² — nearly five times denser.

The compute pipelines differ dramatically. The RX 560 XT has 1,792 shading units, 112 texture mapping units, and 32 ROPs. The RTX PRO 4500 has 10,496 shading units, 328 TMUs, and 112 ROPs. This is roughly a 6x increase in shading units, a 3x increase in TMUs, and a 3.5x increase in ROPs. The Blackwell card also adds 82 RT cores and 328 tensor cores, while the Polaris card has no such dedicated hardware.

Memory architecture is another clear divergence. The RX 560 XT uses 4 GB of GDDR5 with a 256-bit bus, producing 224.0 GB/s of bandwidth. The RTX PRO 4500 uses 32 GB of GDDR7 with a 256-bit bus, producing 896.0 GB/s of bandwidth. Memory clock speeds are listed identically at 1750 MHz, but the effective data rate differs: 7 Gbps for the AMD card versus 28 Gbps for the NVIDIA card.

API support also separates them. The RX 560 XT supports DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.3. The RTX PRO 4500 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The NVIDIA card also uses a PCIe 5.0 x16 interface versus PCIe 3.0 x16 on the AMD card.

Power delivery and physical design show different priorities. The RX 560 XT has a 150 W TDP with a single 6-pin power connector and a suggested 450 W PSU. The RTX PRO 4500 has a 200 W TDP with a single 16-pin connector and a suggested 550 W PSU. Both are dual-slot cards, but the NVIDIA card is longer at 267 mm versus 241 mm, and it also has specified dimensions of 111 mm height and 40 mm width, while the AMD card lists only length.

The Verdict

The data paints an unambiguous picture: these are not competing products. The RTX PRO 4500 Blackwell is overwhelmingly more capable in every architectural and computational dimension — 11.5x the FP32 throughput, 4x the memory bandwidth, 8x the memory capacity, and 6x the shading units. The AMD card's only numerical advantage is its slightly higher average benchmark score (34,133 vs 31,532) and higher percentile rank (79th vs 76th). However, this is likely an artifact of benchmark selection — the RX 560 XT only has two benchmark entries (Geekbench OpenCL and Vulkan), while the RTX PRO 4500 has nine entries including multiple PassMark tests where it scores very low in some categories (e.g., 119 in PassMark DirectX 12).

The RTX PRO 4500 is the clear choice for anyone needing professional-grade compute, ray tracing, tensor acceleration, or large memory pools. The RX 560 XT might still serve basic legacy workloads or light gaming, but its end-of-life status and lack of modern features make it a poor recommendation for new builds. The data suggests the RTX PRO 4500 is a workstation-class card, while the RX 560 XT is a budget consumer product from a previous era.

Head-to-Head Benchmarks

The only shared benchmark between the two cards is Geekbench Vulkan, and the result is decisive. The RTX PRO 4500 scores 221,768, while the RX 560 XT scores 36,879. That is a delta of -83.4% for the AMD card, meaning the NVIDIA card is roughly 6 times faster in this Vulkan compute test.

Beyond that shared metric, the individual benchmark suites tell different stories. The RX 560 XT's Geekbench OpenCL score of 31,387 is comparable to its Vulkan score, suggesting consistent compute performance across APIs. The RTX PRO 4500's PassMark G3D score of 33,360 is nearly identical to its average benchmark score of 31,532, indicating solid overall performance in that suite. However, the RTX PRO 4500 shows extreme variance across PassMark sub-tests: 397 in DirectX 9, 320 in DirectX 11, 204 in DirectX 10, and only 119 in DirectX 12. This is unusual and worth questioning — a card with 50.53 TFLOPS FP32 should not score only 119 in a DirectX 12 rasterization test. The PassMark G2D score of 1,336 and GPU compute score of 19,255 are more in line with expectations for a professional card.

The RTX PRO 4500 also has a 3DMark Steel Nomad DX12 score of 7,025, which is a modern benchmark that the RX 560 XT cannot even run given its older DirectX 12_0 support. The wins are lopsided: the RTX PRO 4500 wins the sole head-to-head benchmark and has seven additional benchmarks to its name, while the RX 560 XT has only two total benchmarks and zero wins in the direct comparison.

Where Each One Wins

The RTX PRO 4500 Blackwell wins in every performance category that matters for modern workloads. Its 50.53 TFLOPS FP32 makes it a compute powerhouse for rendering, simulation, and scientific workloads. The 32 GB of GDDR7 memory with 896.0 GB/s bandwidth is suited for large datasets, 3D scenes, and AI model inference that would exhaust the RX 560 XT's 4 GB frame buffer in seconds. The 82 RT cores enable hardware-accelerated ray tracing, and the 328 tensor cores handle AI acceleration — neither of which the RX 560 XT can do in hardware. The PCIe 5.0 interface and DisplayPort 2.1b outputs further cement its position as a professional workstation card for high-resolution displays and fast data transfer.

The RX 560 XT's wins are limited to legacy scenarios. Its slightly higher average benchmark score (34,133 vs 31,532) and percentile rank (79th vs 76th) suggest that in certain older API workloads, it can hold its own. The 150 W TDP and single 6-pin power connector mean it is easier to power in older systems with limited PSU headroom. Its shorter length of 241 mm may fit in compact cases where the 267 mm RTX PRO 4500 would not. However, these are practical accommodation wins, not performance wins. The RX 560 XT also supports OpenGL 4.6 just like the NVIDIA card, so it can run older OpenGL applications, but with far lower throughput. For anyone running modern DirectX 12 Ultimate workloads, Vulkan 1.4 applications, or any ray-traced or tensor-based task, the RTX PRO 4500 is the only viable option in this comparison.
