Intel Arc Pro B370 vs NVIDIA GeForce RTX 4080 SUPER Comparison

Where Each One Wins

The Intel Arc Pro B370 and NVIDIA GeForce RTX 4080 SUPER occupy completely different positions in the performance spectrum. The RTX 4080 SUPER is a top-tier discrete graphics card, sitting in the 86th percentile of all GPUs in the database, with an average benchmark score of 54,209. The Arc Pro B370, by contrast, is an integrated graphics solution with no recorded benchmark scores and a 50th percentile ranking, meaning the data places it at the median of all GPUs, but without actual performance numbers to substantiate its standing.

Where the RTX 4080 SUPER wins is straightforward: every benchmark category with recorded data. It delivers 52.22 TFLOPS of FP32 compute, 816.0 GTexel/s texture rate, and 285.6 GPixel/s pixel rate. Its 3DMark Steel Nomad DX12 score of 6,600, Geekbench OpenCL score of 219,065, and Geekbench Vulkan score of 260,075 all confirm substantial rendering capability. PassMark scores reinforce this: 34,245 in G3D, 19,822 in GPU compute, and 1,270 in G2D. Even its lowest PassMark result, 134 in DirectX 12, reflects a workload where the card still operates far beyond what an integrated GPU could manage.

The Arc Pro B370 wins in a different domain: power efficiency and physical footprint. It is an IGP with a 25 W TDP, no power connectors, and system-shared memory. The RTX 4080 SUPER requires 320 W, a triple-slot cooler, a 1x 16-pin power connector, and a suggested 700 W PSU. For systems where discrete GPU installation is impossible or undesirable, the Arc Pro B370 is the only viable option between the two. The data shows no benchmark wins for the Intel part, but its existence as an integrated solution means it wins on integration and power draw, not on raw performance.

Architecture Differences

The two GPUs come from different design philosophies and process nodes. The Intel Arc Pro B370 uses the Xe3-LPG architecture on a 3 nm process, fabricated by Intel, as part of the Panther Lake chip. The RTX 4080 SUPER uses Ada Lovelace on a 5 nm process from TSMC, with the AD103 chip. The Intel part is built for low-power integrated deployment, while the NVIDIA part is a high-power discrete card.

Cores differ massively. The Arc Pro B370 has 1,280 shading units, 40 TMUs, 20 ROPs, and 10 ray tracing cores. The RTX 4080 SUPER has 10,240 shading units, 320 TMUs, 112 ROPs, and 80 RT cores, plus 320 tensor cores that the Intel part lacks entirely. The NVIDIA card also has dedicated GDDR6X memory (16 GB on a 256-bit bus with 736.3 GB/s bandwidth), while the Arc Pro B370 uses system-shared memory with system-dependent bandwidth.

Clock behavior also differs. The Arc Pro B370 has a base clock of 300 MHz and a boost of 2400 MHz, a wide boost range typical of power-constrained integrated parts. The RTX 4080 SUPER has a base of 2295 MHz and boost of 2550 MHz, with memory clocked at 1438 MHz (23 Gbps effective). Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API compatibility is identical.

Transistor counts and die sizes are only recorded for the NVIDIA part: 45,900 million transistors on a 379 mm² die, giving a density of 121.1M per mm². The Intel part's transistor count and die size are listed as unknown. The RTX 4080 SUPER is a large, complex chip; the Arc Pro B370 is designed to fit within a mobile or embedded processor package.

The Verdict

The recorded data points to a clear split. For any workload requiring substantial graphics throughput, the RTX 4080 SUPER is the only choice with measurable performance. Its benchmark scores, memory bandwidth, and compute rates place it far ahead of the Arc Pro B370, which has no benchmark entries in the database. The NVIDIA card also holds a 86th percentile ranking versus the Intel part's 50th, a gap that reflects the absence of verified performance data for the integrated GPU.

The Arc Pro B370 is appropriate for systems where a discrete card cannot be used. Its 25 W TDP, IGP form factor, and lack of power connectors make it suitable for compact or low-power builds. The RTX 4080 SUPER, at 320 W with a triple-slot footprint and 310 mm length, demands a full-size chassis and robust power delivery.

Users who need ray tracing performance will note the RTX 4080 SUPER's 80 RT cores versus the Intel part's 10. Users who need tensor operations have no option but the NVIDIA card, since the Arc Pro B370 has no tensor cores at all. The data shows no scenario where the Intel part outperforms the NVIDIA card in any benchmark, but the Intel part serves a different market segment entirely.

Head-to-Head Benchmarks

No head-to-head benchmark data exists between these two GPUs, so direct comparisons must rely on the RTX 4080 SUPER's recorded scores and the absence of any for the Intel part. The RTX 4080 SUPER's average benchmark score of 54,209 places it close to the NVIDIA GeForce RTX 4080, which averages 54,247, a delta of -0.1%. It also sits near the AMD Radeon Pro W5700X (54,828, -1.1%), the AMD Radeon RX 6750 GRE 12 GB (55,698, -2.7%), and the AMD Radeon 8060S (55,757, -2.8%). These deltas show the RTX 4080 SUPER is competitive with its immediate peers, trailing the fastest rival by less than 3%.

Specific benchmark results for the RTX 4080 SUPER include a 3DMark Steel Nomad DX12 score of 6,600, a Geekbench OpenCL score of 219,065, and a Geekbench Vulkan score of 260,075. PassMark tests show 34,245 in G3D, 19,822 in GPU compute, and 1,270 in G2D. The DirectX 10, 11, 12, and 9 scores are 193, 301, 134, and 381 respectively. These numbers establish a performance baseline that the Arc Pro B370 simply cannot approach, given its FP32 rate of 6.144 TFLOPS compared to 52.22 TFLOPS for the NVIDIA card, an order of magnitude difference.

The largest gap in favor of the RTX 4080 SUPER appears in pixel rate: 285.6 GPixel/s versus 48.00 GPixel/s for the Intel part. Texture rate shows a similar divide: 816.0 GTexel/s versus 96.00 GTexel/s. Ray tracing hardware differs by a factor of eight, with 80 RT cores on the NVIDIA card versus 10 on the Intel part. Every measurable metric favors the discrete card, and the absence of benchmark data for the Arc Pro B370 means no counterbalancing evidence exists.

Specification Differences

The two GPUs differ in nearly every specification category. The Arc Pro B370 is built on Intel's 3 nm process with the Xe3-LPG architecture, while the RTX 4080 SUPER uses TSMC's 5 nm process with Ada Lovelace. The Intel part has 1,280 shading units, 40 TMUs, and 20 ROPs; the NVIDIA part has 10,240 shading units, 320 TMUs, and 112 ROPs. RT core counts are 10 versus 80, and tensor cores are absent on the Intel part versus 320 on the NVIDIA card.

Clock speeds: the Arc Pro B370 runs at 300 MHz base and 2400 MHz boost. The RTX 4080 SUPER runs at 2295 MHz base and 2550 MHz boost, with memory at 1438 MHz (23 Gbps effective). Memory configuration diverges completely: system-shared on the Intel part versus 16 GB GDDR6X with 256-bit bus and 736.3 GB/s bandwidth on the NVIDIA card.

Power and physical characteristics separate them further. The Arc Pro B370 has a 25 W TDP, is an IGP, uses no power connectors, and has no suggested PSU. The RTX 4080 SUPER has a 320 W TDP, is triple-slot, requires a 1x 16-pin power connector, and suggests a 700 W PSU. The Intel part's display outputs are portable-device dependent, while the NVIDIA card offers 1x HDMI 2.1 and 3x DisplayPort 1.4a. Bus interfaces are IGP versus PCIe 4.0 x16. The RTX 4080 SUPER measures 310 mm by 140 mm by 61 mm; the Arc Pro B370 has no listed dimensions. Release dates differ as well: the Intel part is dated January 2026 and marked active, while the NVIDIA card was released in January 2024 and is end-of-life. The RTX 4080 SUPER has a launch MSRP of 999 USD.
