AMD Radeon Pro 450 vs NVIDIA GeForce GTX 465 Comparison

Head-to-Head Benchmarks

The only directly comparable benchmark between these two GPUs in the database is Geekbench OpenCL, and the results show a narrow victory for the NVIDIA GeForce GTX 465. The GTX 465 recorded a score of 9294, while the AMD Radeon Pro 450 scored 9002. This translates to a 3.1% advantage for the NVIDIA part, a margin that is meaningful but hardly decisive.

The Radeon Pro 450, however, holds a clear edge in the broader benchmark suite. Its average benchmark score across all recorded tests is 10804, compared to the GTX 465's 9294. That is a 16.3% gap in favor of the AMD card. The Radeon Pro 450 also posts scores of 12893 in Geekbench Metal and 10518 in Geekbench Vulkan, two tests the GTX 465 does not have recorded results for. These additional data points suggest that the AMD card is the more versatile performer in modern API workloads.

Looking at the percentile rankings, the Radeon Pro 450 sits at the 49th percentile among all GPUs, while the GTX 465 sits at the 46th. This is a small overall ranking difference, but it aligns with the average score differential. The GTX 465's rival set includes the NVIDIA GeForce GTX 960, which it trails by just 0.2%, and the AMD Radeon Vega 8, which it beats by 0.8%. The Radeon Pro 450's nearest rivals include the NVIDIA Quadro K2200 (ahead by 0.4%) and the NVIDIA GeForce MX350 (behind by 0.7%), placing it in a slightly higher performance tier.

The head-to-head OpenCL result, while a loss for the AMD card, should be weighed against its superior showing in Metal and Vulkan. The database indicates that the GTX 465 wins exactly one head-to-head test, while the Radeon Pro 450 wins none, but the absence of comparable data in two of the three benchmark categories limits the strength of that conclusion.

Where Each One Wins

The NVIDIA GeForce GTX 465 wins in raw OpenCL compute performance. Its 9294 score beats the Radeon Pro 450's 9002 by 3.1%, making it the stronger choice for workloads that rely specifically on OpenCL execution. This is a narrow win, however, and the margin is within what could be considered run-to-run variance for many applications.

The AMD Radeon Pro 450 wins in overall average performance. Its 10804 average across all benchmarks is 16.3% higher than the GTX 465's 9294. This advantage is driven by its strong showings in Geekbench Metal (12893) and Geekbench Vulkan (10518), both of which are modern, cross-platform APIs that the GTX 465 either does not support or has no recorded data for. For users running Metal-based applications on macOS or Vulkan-based games, the Radeon Pro 450 is the clear winner.

The GTX 465 also shows a theoretical advantage in memory bandwidth, with 102.7 GB/s versus the Radeon Pro 450's 81.28 GB/s, and a wider 256-bit bus versus 128-bit. Yet this did not translate into a dominant OpenCL margin, and the AMD card compensates with higher FP32 throughput (1024.0 GFLOPS versus 855.4 GFLOPS) and a much higher texture fill rate (32.00 GTexel/s versus 26.75 GTexel/s).

For pixel fill rate, the GTX 465 leads at 13.38 GPixel/s against 12.80 GPixel/s, a small 4.5% edge. The GTX 465 also has double the ROPs (32 versus 16), which can help in certain rasterization-heavy scenarios. But the Radeon Pro 450's higher shading unit count (640 versus 352) and newer architecture give it a broader advantage in shader-bound workloads.

Architecture Differences

The AMD Radeon Pro 450 is built on the Baffin chip using the GCN 4.0 architecture, fabricated on a 14 nm process at GlobalFoundries. It packs 3,000 million transistors into a 123 mm² die, yielding a transistor density of 24.4 million per mm². This is a modern, power-efficient design that operates at a TDP of just 35 W, making it suitable for compact MXM modules in portable devices.

The NVIDIA GeForce GTX 465 uses the GF100 chip with the Fermi architecture, fabricated on a 40 nm process at TSMC. It contains 3,100 million transistors on a much larger 529 mm² die, giving it a transistor density of only 5.9 million per mm². This older, larger design consumes 200 W and requires a dual-slot cooler along with 2x 6-pin power connectors and a suggested 550 W power supply. The GTX 465 is a 241 mm card, while the Radeon Pro 450's dimensions are not recorded.

Memory configurations differ substantially. The Radeon Pro 450 has 2 GB of GDDR5 on a 128-bit bus, running at 1270 MHz (5.1 Gbps effective), delivering 81.28 GB/s of bandwidth. The GTX 465 has 1024 MB of GDDR5 on a 256-bit bus, running at 802 MHz (3.2 Gbps effective), delivering 102.7 GB/s. The NVIDIA card has more bandwidth but half the capacity, which can be a limiting factor in modern workloads.

The Radeon Pro 450 supports DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.3. The GTX 465 supports DirectX 12 (11_0), OpenGL 4.6, but has no Vulkan support recorded. The AMD card also supports PCIe 3.0 x8, while the GTX 465 uses PCIe 2.0 x16. Display outputs on the Radeon Pro 450 are portable device dependent, while the GTX 465 offers 2x DVI and 1x mini-HDMI 1.3a.

The Radeon Pro 450 was released on October 29, 2016, as part of the Radeon Pro Mac (400 Series) generation. The GTX 465 was released on May 30, 2010, as part of the GeForce 400 generation, with a predecessor in the GeForce 200 series and a successor in the GeForce 500 series. Both are now end-of-life products.

The Verdict

Based strictly on the recorded data, the AMD Radeon Pro 450 is the better overall GPU. Its average benchmark score of 10804 is 16.3% higher than the GTX 465's 9294, and it achieves a higher percentile ranking (49th versus 46th). The Radeon Pro 450 also delivers modern API support including Vulkan 1.3 and DirectX 12 (12_0), while the GTX 465 lacks Vulkan and only reaches DirectX 12 (11_0).

The NVIDIA GeForce GTX 465 wins only in the single direct comparison available: Geekbench OpenCL, where it leads by 3.1%. It also offers higher memory bandwidth (102.7 GB/s versus 81.28 GB/s) and a wider memory bus (256-bit versus 128-bit), but these advantages do not overcome the AMD card's lead in average performance and modern feature support.

For users prioritizing OpenCL compute performance specifically, the GTX 465 is the choice. For anyone needing broad compatibility with modern graphics APIs, better average performance, lower power consumption (35 W versus 200 W), and a more recent architecture, the Radeon Pro 450 is the superior option. The data supports the Radeon Pro 450 as the more capable and future-proof part.

The GTX 465's launch MSRP was 279 USD, a fact worth noting for historical context, but the Radeon Pro 450 has no recorded launch price.
