AMD Radeon Pro 455 vs NVIDIA GeForce GTX 560 Ti Comparison

Head-to-Head Benchmarks

The only direct benchmark comparison recorded in the database is the Geekbench OpenCL test. Here, the NVIDIA GeForce GTX 560 Ti posts a score of 10690, while the AMD Radeon Pro 455 reaches 10336. That gives the older NVIDIA card a 3.3% advantage, a modest but measurable lead in raw OpenCL compute performance. The delta is small enough that real-world differences would be difficult to perceive, but the recorded data does show the GTX 560 Ti as the winner in this single head-to-head matchup.

Looking beyond the direct comparison, the AMD Radeon Pro 455 has a broader benchmark footprint. It records scores in three separate tests: 15916 in Geekbench Metal, 12240 in Geekbench Vulkan, and 10336 in Geekbench OpenCL. Its average benchmark score across all recorded tests is 12831. The NVIDIA GeForce GTX 560 Ti, by contrast, has only one recorded benchmark result, the Geekbench OpenCL score of 10690, which also serves as its average benchmark score.

The percentile data places the AMD card slightly higher in the overall GPU landscape. The Radeon Pro 455 sits at the 52nd percentile of all GPUs, while the GTX 560 Ti sits at the 49th percentile. This suggests that, when considering the full spread of recorded results, the AMD part occupies a marginally stronger position relative to the entire database population.

The nearest rival data reinforces this interpretation. The Radeon Pro 455's average score of 12831 places it within 0.5% of the NVIDIA GeForce GTX 670 (12773), within 0.1% of the AMD FirePro W5100 (12847), and within 0.3% of the AMD Radeon 740M (12870). It is essentially tied with the NVIDIA GeForce GTX 590, which scores 12830. The GTX 560 Ti's average of 10690 places it 0.6% ahead of the AMD Radeon RX 6600S (10629), 1% ahead of the AMD Radeon R9 M275X (10582), 0.7% behind the NVIDIA Quadro K2200 (10761), and 1.1% behind the AMD Radeon Pro 450 (10804). In short, the AMD Radeon Pro 455 competes in a higher performance tier than the GTX 560 Ti, even though the direct OpenCL comparison slightly favors the NVIDIA card.

Architecture Differences

The two cards come from different architectural generations and manufacturing approaches. The AMD Radeon Pro 455 uses the Baffin chip built on GCN 4.0 architecture, produced on a 14 nm process at GlobalFoundries. The NVIDIA GeForce GTX 560 Ti uses the GF114 chip built on Fermi 2.0 architecture, produced on a 40 nm process at TSMC. The process node gap is substantial: 14 nm versus 40 nm. This shows up clearly in transistor density. The AMD chip packs 3,000 million transistors into a die size of 123 mm², yielding a density of 24.4 million transistors per square millimeter. The NVIDIA chip contains 1,950 million transistors across a much larger 332 mm² die, for a density of only 5.9 million transistors per square millimeter.

The memory subsystems differ in capacity and bandwidth. The Radeon Pro 455 has 2 GB of GDDR5 memory on a 128 bit bus, delivering 81.28 GB/s of bandwidth. The GTX 560 Ti has 1024 MB of GDDR5 memory on a wider 256 bit bus, delivering 128.3 GB/s. The NVIDIA card therefore has a clear bandwidth advantage, 58% higher than the AMD part, despite carrying half the memory capacity. The effective memory clock also differs: the AMD card runs at 5.1 Gbps effective, while the NVIDIA card runs at 4 Gbps effective.

Compute resources are organized differently. The Radeon Pro 455 has 768 shading units, 48 texture mapping units, and 16 raster output units. The GTX 560 Ti has 384 shading units, 64 TMUs, and 32 ROPs. The AMD card has double the shading units but fewer TMUs and ROPs. The resulting pixel rates are nearly identical: 13.68 GPixel/s for the AMD card versus 13.17 GPixel/s for the NVIDIA card. Texture rate favors the NVIDIA card, which reaches 52.67 GTexel/s versus 41.04 GTexel/s for the AMD part. Floating point performance is close: the Radeon Pro 455 delivers 1,313.3 GFLOPS of FP32 compute, while the GTX 560 Ti delivers 1,263.4 GFLOPS. The AMD card also supports FP16 at a 1:1 ratio with the same 1,313.3 GFLOPS figure, while the NVIDIA card has no recorded FP16 capability.

Power and physical design diverge sharply. The Radeon Pro 455 has a TDP of 35 W and uses an MXM Module form factor with no power connectors. The GTX 560 Ti has a TDP of 170 W, uses a dual-slot design, requires two 6-pin power connectors, and carries a suggested PSU rating of 450 W. The NVIDIA card is also a full-length board at 229 mm (9 inches). The AMD card's dimensions are not recorded, but its MXM form factor and lack of power connectors indicate a mobile-oriented design. The bus interface also differs: the AMD card uses PCIe 3.0 x8, while the NVIDIA card uses PCIe 2.0 x16.

API support shows a generation gap. The Radeon Pro 455 supports DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.3. The GTX 560 Ti supports DirectX 12 (11_0) and OpenGL 4.6, but has no recorded Vulkan support. The AMD card also has a recorded Vulkan benchmark score of 12240, confirming functional Vulkan capability. The NVIDIA card's lack of a Vulkan score may reflect either missing support or the absence of a recorded test; the database lists Vulkan as null for that card. Display outputs for the AMD card are listed as "Portable Device Dependent," while the GTX 560 Ti offers 2x DVI and 1x mini-HDMI 1.3a. The release dates are far apart: the GTX 560 Ti launched on 2011-01-24, and the Radeon Pro 455 launched on 2016-10-29. Both are end-of-life products. The GTX 560 Ti had a launch MSRP of 249 USD; the Radeon Pro 455 has no recorded launch MSRP.

The Verdict

The data presents a nuanced picture. In the single direct head-to-head test, Geekbench OpenCL, the NVIDIA GeForce GTX 560 Ti wins by 3.3%. That is a real result and should not be dismissed. However, the overall benchmark record favors the AMD Radeon Pro 455. Its average benchmark score of 12831 is 20% higher than the GTX 560 Ti's 10690. It also holds a higher percentile ranking, 52nd versus 49th, and its nearest rivals are significantly faster cards. The Radeon Pro 455 is effectively tied with the GeForce GTX 670 and GTX 590, both of which sit far above the GTX 560 Ti's competitive bracket.

Architecturally, the AMD card is the more modern part. It uses a 14 nm process, supports Vulkan, has double the shading units, and consumes only 35 W versus 170 W. The NVIDIA card counters with higher memory bandwidth, more texture units, more ROPs, and a wider memory bus. In raw OpenCL compute, that bandwidth and texture throughput appear to give the GTX 560 Ti a slight edge over the specific AMD part tested here.

For a user choosing between these two today, the decision depends on the workload. If the task is OpenCL compute and the software is sensitive to memory bandwidth and texture rate, the GTX 560 Ti's narrow win in the recorded test is the only direct evidence available. If the task involves Vulkan, requires more than 1 GB of memory, or demands low power consumption, the Radeon Pro 455 is the only one of the two with recorded support and capacity for those scenarios. The AMD card also has a much higher average score and a better percentile position, indicating stronger overall performance across the broader database. The GTX 560 Ti's 249 USD launch MSRP is its only recorded pricing detail; the AMD card has none, so any cost comparison is not possible from the data.
