GPU Comparison

NVIDIA GeForce GTX 465 and Intel Arc A380 represent two very different eras of GPU design, separated by over a decade of architectural evolution. The data shows a single head-to-head benchmark result, with the Intel card delivering a decisive victory in compute workloads. However, the GTX 465 holds its own in the broader performance percentile rankings, creating an interesting split between raw legacy compute and modern feature sets.

Where Each One Wins

The Intel Arc A380 is the clear winner in the only direct benchmark comparison available. In Geekbench OpenCL, the A380 scores 38,224 against the GTX 465’s 9,294, a delta of -75.7% from the perspective of the older card. This is not a marginal lead; it is a 4.1x advantage in raw compute throughput. The A380’s 4.198 TFLOPS FP32 performance, 1,024 shading units, and 64 TMUs dwarf the GTX 465’s 855.4 GFLOPS, 352 shading units, and 44 TMUs. For any workload that leverages OpenCL, be it rendering, physics simulation, or data processing, the Arc A380 is the only practical choice between these two.

The GTX 465, however, wins on relative standing among all GPUs. It sits at the 46th percentile of all GPUs, while the Arc A380 sits at the 44th percentile. The GTX 465’s average benchmark score of 9,294 places it within 0.8% of the AMD Radeon Vega 8 and within 0.2% of the NVIDIA GeForce GTX 960. The A380’s average score of 8,558 is lower, placing it 1.4% behind the AMD Radeon 880M and 1.2% behind the NVIDIA GeForce MX330. In terms of pure average performance across all benchmarks, the older Fermi card edges out the newer Alchemist part.

The A380 wins decisively on features and modern API support. It supports DirectX 12 Ultimate (12_2), Vulkan 1.4, and has 8 dedicated ray tracing cores. The GTX 465 only supports DirectX 12 (11_0) and has no Vulkan support listed, nor any ray tracing hardware. The A380 also has a massive memory advantage with 6 GB of GDDR6 on a 96-bit bus delivering 186.0 GB/s of bandwidth, versus the GTX 465’s 1 GB of GDDR5 on a 256-bit bus at 102.7 GB/s. While the GTX 465 has a wider bus, the A380’s newer memory technology and higher capacity make it more suitable for modern textures and larger datasets.

The Verdict

Pick the Intel Arc A380 if you need modern API support, ray tracing, or any form of compute acceleration beyond what a 2010-era GPU can provide. The OpenCL benchmark is not close, and the A380’s architecture is fundamentally designed for workloads that did not exist when the GTX 465 launched. The 8 RT cores and DirectX 12 Ultimate support mean it can handle current-generation gaming features and future-proofed applications. Its 75 W TDP and suggested 250 W PSU also make it far easier to integrate into a modern system than the GTX 465’s 200 W TDP and 550 W PSU requirement.

Pick the NVIDIA GeForce GTX 465 only if you are building a period-correct system or need to run legacy software that relies on its specific feature set. Its 46th percentile standing is marginally better than the A380’s 44th, and its OpenCL score of 9,294 is competitive with the GTX 960 and Radeon Vega 8. But the data shows this is a card that performs at the level of a mid-range 2014-2016 laptop GPU, not a modern desktop part. It has no Vulkan support, no ray tracing, and only 1 GB of VRAM, which will be a hard bottleneck in any modern workload. The GTX 465 is a curiosity; the A380 is a usable tool.

Head-to-Head Benchmarks

The single head-to-head test is Geekbench OpenCL. The Intel Arc A380 scores 38,224, while the NVIDIA GeForce GTX 465 scores 9,294. The delta percentage is -75.7%, meaning the GTX 465 trails by over 75% of the A380’s score. This is the largest possible margin in this comparison, and it reflects the architectural gulf between the two cards.

The GTX 465’s 9,294 OpenCL score places it just 0.1% behind the GTX 850M (9,302) and 0.2% behind the Radeon R7 M380 (9,313). It is 0.2% ahead of the GTX 960 (9,273) and 0.8% ahead of the Radeon Vega 8 (9,221). This clustering suggests the Fermi card is performing at the level of entry-to-mid-range mobile GPUs from 2014-2016, which is respectable for a 2010 desktop part but not competitive with anything modern.

The A380’s 38,224 OpenCL score puts it in a different performance class entirely. Its nearest rivals are the AMD FirePro W5170M (8,595, delta -0.4%), the AMD Radeon HD 8870M (8,462, delta 1.1%), the NVIDIA GeForce MX330 (8,458, delta 1.2%), and the AMD Radeon 880M (8,436, delta 1.4%). Note that the A380’s average score across all benchmarks (8,558) is much lower than its OpenCL peak, indicating that its compute performance is its strong suit while its gaming-oriented benchmarks (PassMark DirectX 9-12 scores ranging from 35 to 73) are less impressive.

Architecture Differences

The NVIDIA GeForce GTX 465 uses the GF100 chip based on the Fermi architecture, manufactured on a 40 nm process at TSMC. It contains 3,100 million transistors on a 529 mm² die, yielding a transistor density of 5.9 million per mm². This was a large, power-hungry chip by 2010 standards. The Intel Arc A380 uses the DG2-128 chip based on the Xe-HPG architecture, manufactured on a 6 nm process also at TSMC. It contains 7,200 million transistors on a 157 mm² die, yielding a density of 45.9 million per mm², over 7.7x the transistor density of the Fermi chip.

The compute configurations are fundamentally different. The GTX 465 has 352 shading units, 44 TMUs, and 32 ROPs. The Arc A380 has 1,024 shading units, 64 TMUs, and 32 ROPs. The A380 also adds 8 RT cores, which the GTX 465 lacks entirely. The pixel rate for the A380 is 65.60 GPixel/s versus 13.38 GPixel/s for the GTX 465, and the texture rate is 131.2 GTexel/s versus 26.75 GTexel/s.

The memory subsystems are also radically different. The GTX 465 uses 1 GB of GDDR5 on a 256-bit bus with 102.7 GB/s bandwidth. The A380 uses 6 GB of GDDR6 on a 96-bit bus with 186.0 GB/s bandwidth.
