The Verdict

The data presents a clear segmentation between these two products. The NVIDIA GeForce RTX 4080 SUPER is the performance-focused option, with a percentile rank of 86 versus the Arc Pro B65's 50, and it carries substantial compute resources. The RTX 4080 SUPER has a launch MSRP of 999 USD, which the database records as its only pricing reference.

For users prioritizing raw graphics throughput, the RTX 4080 SUPER is the logical selection based on its benchmark-documented performance. Its 10240 shading units, 320 tensor cores, and 52.22 TFLOPS FP32 throughput represent a class of hardware that the Arc Pro B65 cannot match on paper. The NVIDIA card also benefits from having a full set of recorded benchmark scores across DirectX 10, 11, 12, and 9, plus OpenCL, Vulkan, and compute workloads.

The Intel Arc Pro B65, however, is the choice for memory-heavy workloads. Its 32 GB GDDR6 frame buffer is double the capacity of the RTX 4080 SUPER. The Intel card also presents a lower power footprint at 200 W TDP versus 320 W, and it uses a more common 8-pin power connector with a 550 W PSU recommendation. The Arc Pro B65 is an active product with a 2026 release, whereas the RTX 4080 SUPER is end-of-life.

The verdict from the recorded data: the RTX 4080 SUPER is for applications where compute power and proven benchmark scores dominate. The Arc Pro B65 is for scenarios requiring large memory capacity, newer display connectivity (DisplayPort 2.1), and lower system power demands. These are not interchangeable products; they serve different priorities.

Head-to-Head Benchmarks

The database includes no direct head-to-head benchmark results between these two cards. The wins counter shows 0 for each side, and the headToHeadBenchmarks array is empty.

The only benchmark data available belongs to the RTX 4080 SUPER. Its 3DMark Steel Nomad DX12 score is 6600. In Geekbench, it scores 219065 in OpenCL and 260075 in Vulkan. Passmark results include 193 in DirectX 10, 301 in DirectX 11, 134 in DirectX 12, and 381 in DirectX 9. The Passmark G2D score is 1270, G3D is 34245, and GPU compute is 19822.

When compared to its nearest rivals in the database, the RTX 4080 SUPER sits within a narrow band. The NVIDIA GeForce RTX 4080 has an average score of 54247, which is 0.1% higher than the 4080 SUPER's 54209. The AMD Radeon Pro W5700X averages 54828, 1.1% higher. The AMD Radeon RX 6750 GRE 12 GB averages 55698, 2.7% higher, and the AMD Radeon 8060S averages 55757, 2.8% higher. This means the 4080 SUPER trails all four recorded rivals by small margins, between 0.1% and 2.8%.

Without any recorded scores for the Arc Pro B65, the head-to-head comparison must rely on the specification differences and the percentile gap. The Arc Pro B65's 50th percentile ranking places it at the median of all GPUs in the database, while the RTX 4080 SUPER's 86th percentile places it well above the median. The performance gap implied by these percentiles is substantial, but the absence of specific benchmark numbers for the Intel card prevents a precise delta calculation.

Specification Differences

The two cards differ across nearly every measured specification. The Arc Pro B65 uses 2560 shading units, 160 TMUs, and 80 ROPs. The RTX 4080 SUPER uses 10240 shading units, 320 TMUs, and 112 ROPs. The NVIDIA card has 80 RT cores and 320 tensor cores, while the Intel card has 20 RT cores and no tensor core count listed.

Pixel and texture rates diverge significantly. The RTX 4080 SUPER achieves 285.6 GPixel/s and 816.0 GTexel/s. The Arc Pro B65 delivers 192.0 GPixel/s and 384.0 GTexel/s. FP32 throughput is 52.22 TFLOPS for NVIDIA versus 12.29 TFLOPS for Intel. FP16 is 52.22 TFLOPS (1:1) for NVIDIA and 24.58 TFLOPS (2:1) for Intel.

Memory specifications differ in capacity and type: 32 GB GDDR6 for Intel versus 16 GB GDDR6X for NVIDIA. Bandwidth favors NVIDIA at 736.3 GB/s versus 608.0 GB/s. Both use a 256-bit bus. Memory clocks are 2375 MHz (19 Gbps effective) for Intel and 1438 MHz (23 Gbps effective) for NVIDIA.

Clock behavior also differs. The Intel card runs at a fixed 2400 MHz for both base and boost. The NVIDIA card has a 2295 MHz base and a 2550 MHz boost. The RTX 4080 SUPER is a triple-slot card with dimensions of 310 mm length, 140 mm height, and 61 mm width. The Arc Pro B65 is dual-slot with no dimensions recorded.

Power and connectivity differ as well. Intel uses 200 W TDP with a single 8-pin connector and 550 W suggested PSU. NVIDIA uses 320 W TDP with a single 16-pin connector and 700 W suggested PSU. The bus interface is PCIe 5.0 x16 for Intel and PCIe 4.0 x16 for NVIDIA. Display outputs are 4x DisplayPort 2.1 for Intel and 1x HDMI 2.1 plus 3x DisplayPort 1.4a for NVIDIA. Both cards support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

Architecture Differences

The Intel Arc Pro B65 is built on the Xe2-HPG architecture with the BMG-G21 chip, part of the Battlemage (Pro Series) generation. The NVIDIA GeForce RTX 4080 SUPER uses the Ada Lovelace architecture with the AD103 chip, part of the GeForce 40 series.

Both are fabricated on a 5 nm process at TSMC, but the transistor counts differ enormously. The RTX 4080 SUPER packs 45,900 million transistors on a 379 mm² die, yielding a density of 121.1M per mm². The Arc Pro B65 contains 19,600 million transistors on a 272 mm² die, with a density of 72.1M per mm². The NVIDIA chip uses more than twice the transistor count and achieves a substantially higher density.

The RTX 4080 SUPER's architecture includes tensor cores, which are absent from the Intel specification list. This indicates a fundamental difference in compute capability. The NVIDIA card also has four times the RT cores (80 versus 20), aligning with its higher ray tracing throughput expectations.

The Intel card's architecture supports a 2:1 FP16 ratio, meaning it can perform half-precision math at twice the FP32 rate. The NVIDIA card operates at 1:1, with FP16 throughput equal to FP32. This architectural choice affects how each card handles mixed-precision workloads.

The Arc Pro B65's newer release date, 2026-03-31, places it in the Battlemage generation with PCIe 5.0 support, whereas the RTX 4080 SUPER from 2024-01-30 uses PCIe 4.0. The Intel card's DisplayPort 2.1 outputs represent a newer display standard than the NVIDIA card's DisplayPort 1.4a.

Where Each One Wins

The RTX 4080 SUPER wins decisively in raw compute performance. Its FP32 throughput of 52.22 TFLOPS is over four times the Arc Pro B65's 12.29 TFLOPS. Texture rate is 816.0 GTexel/s versus 384.0 GTexel/s, and pixel rate is 285.6 GPixel/s versus 192.0 GPixel/s. The NVIDIA card has 320 tensor cores, which the Intel card lacks entirely. These figures point to workloads involving complex shaders, tensor operations, and high-resolution rendering.

The RTX 4080 SUPER also wins in memory bandwidth with 736.3 GB/s versus 608.0 GB/s, which benefits texture-heavy scenes and large data transfers. Its 10240 shading units provide a massive parallel processing advantage over the Intel card's 2560. The recorded benchmark scores, while not directly comparable to the unbenchmarked Intel card, show a GPU that performs in the 86th percentile with an average score of 54209.

The Arc Pro B65 wins in memory capacity with 32 GB versus 16 GB. This matters for workloads that require large datasets resident in VRAM, such as certain professional visualization tasks, large language model inference, or rendering scenes with massive texture sets. The Intel card also wins in power efficiency per the TDP figures: 200 W versus 320 W. Its 550 W suggested PSU is lower than the NVIDIA card's 700 W, and the 8-pin connector is more universally compatible than the 16-pin.

The Arc Pro B65 wins on display connectivity with four DisplayPort 2.1 outputs, supporting higher bandwidth per port than DisplayPort 1.4a. Its PCIe 5.0 x16 interface is a newer standard than the RTX 4080 SUPER's PCIe 4.0 x16, which could matter for future system compatibility.

The production status favors Intel as well: the Arc Pro B65 is Active, while the RTX 4080 SUPER is End-of-life. For organizations planning long-term deployments, the active product has a clearer support horizon.

In summary, the RTX 4080 SUPER is the compute and bandwidth leader, suitable for performance-critical graphics and tensor workloads. The Arc Pro B65 is the capacity and efficiency leader, suited for memory-bound tasks, multi-display setups, and systems with stricter power budgets. The absence of benchmark data for the Intel card means its actual performance level remains unquantified in the database, but the specification differences provide a clear directional picture.
