Intel Arc B370 vs NVIDIA GeForce RTX 4080 Mobile Comparison

Head-to-Head Benchmarks

The recorded data shows no direct head-to-head benchmark results between the Intel Arc B370 and the NVIDIA GeForce RTX 4080 Mobile. The database contains only one benchmark entry for the Intel part, a 3DMark Steel Nomad DX12 score of 1184, while the NVIDIA part carries a more extensive suite of nine benchmark scores. Without overlapping tests, direct comparison relies on average benchmark scores and percentile placement.

The Intel Arc B370 holds an average benchmark score of 1184. The NVIDIA GeForce RTX 4080 Mobile posts an average benchmark score of 38135. That difference places the two parts in entirely different performance strata. The Intel part sits at the 5th percentile among all GPUs in the database, while the NVIDIA part sits at the 81st percentile. The gap in raw average score is roughly 32 times, indicating a fundamental separation in compute capability.

The NVIDIA part's nearest rivals in the database include the NVIDIA GeForce MX570 with an average score of 38299 and a delta of -0.4%, the NVIDIA GeForce RTX 5080 Mobile with 38349 and -0.6%, the NVIDIA GeForce RTX 4070 with 37648 and 1.3%, and the NVIDIA Tesla P4 with 37628 and 1.3%. These deltas show the RTX 4080 Mobile trading blows with the RTX 4070 desktop part and the Tesla P4, trailing them by 1.3% while sitting just behind the MX570 and the RTX 5080 Mobile.

The Intel Arc B370's nearest rivals are all older or lower-tier parts. The ATI Mobility Radeon HD 5570 scores 1186 with a delta of -0.2%, the ATI Radeon HD 5770 scores 1190 with -0.5%, the AMD Radeon HD 7650M scores 1192 with -0.7%, and the AMD FirePro M2000 scores 1168 with 1.4%. The Intel part essentially matches these legacy GPUs, trailing them by fractions of a percent while leading the FirePro M2000 by 1.4%. The data indicates the Arc B370 performs in the same class as decade-old discrete mobile and desktop parts.

The RTX 4080 Mobile's individual benchmark results show its strongest showing in Geekbench OpenCL with 159575 and Geekbench Vulkan with 145807. PassMark G3D delivers 24926, while PassMark GPU Compute reaches 11191. The PassMark DirectX 10 score of 157, DirectX 11 score of 244, DirectX 12 score of 96, DirectX 9 score of 286, and G2D score of 929 complete the picture. These numbers suggest a part that scales particularly well in compute-oriented workloads rather than legacy DirectX rasterization tests.

Architecture Differences

The two GPUs diverge sharply at the architectural level. The Intel Arc B370 uses the Xe3-LPG architecture built on Intel's 3 nm process node, while the NVIDIA GeForce RTX 4080 Mobile uses Ada Lovelace on TSMC's 5 nm process. The Intel chip is codenamed Panther Lake, part of the Arc Graphics-M generation, whereas the NVIDIA part uses the AD104 chip in the GeForce 40 Mobile generation.

Intel does not disclose transistor counts or die size for the Arc B370, but NVIDIA's AD104 packs 35,800 million transistors on a 294 mm² die with a transistor density of 121.8M per mm². The Intel part integrates memory as System Shared, meaning it draws from system memory rather than dedicated VRAM. The NVIDIA part uses 12 GB of GDDR6 on a 192 bit bus with 432.0 GB/s bandwidth. The Intel memory clock is listed as System Shared, while the NVIDIA memory runs at 2250 MHz with 18 Gbps effective.

Shading hardware differs dramatically. The Intel Arc B370 has 1280 shading units, 40 texture mapping units, 20 raster output units, and 10 ray tracing cores. The NVIDIA GeForce RTX 4080 Mobile has 7424 shading units, 232 TMUs, 80 ROPs, 58 RT cores, and 232 tensor cores. The NVIDIA part also carries tensor cores for AI acceleration, a feature the Intel part does not list.

Clock speeds tell a different story. The Intel Arc B370 runs a base clock of 300 MHz and a boost clock of 2400 MHz. The NVIDIA part runs a base clock of 1290 MHz and a boost clock of 1665 MHz. The Intel part boosts substantially higher, but the NVIDIA part starts from a much higher base and uses far more hardware to deliver throughput.

Pixel and texture rates follow the hardware counts. The Intel part delivers 48.00 GPixel/s and 96.00 GTexel/s. The NVIDIA part delivers 133.2 GPixel/s and 386.3 GTexel/s. Floating point performance shows the NVIDIA part at 24.72 TFLOPS FP32 and 24.72 TFLOPS FP16 at 1:1 ratio, while the Intel part delivers 6.144 TFLOPS FP32 and 12.29 TFLOPS FP16 at 2:1 ratio.

Power envelopes differ significantly. The Intel Arc B370 carries a 25 W TDP, while the NVIDIA GeForce RTX 4080 Mobile carries a 110 W TDP. Both use IGP slot width with no power connectors and portable device dependent display outputs. The Intel part uses an IGP bus interface, while the NVIDIA part uses PCIe 4.0 x16.

Both parts support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The NVIDIA part's predecessor is listed as GeForce 30 Mobile and its successor as GeForce 50 Mobile. The Intel part lists no predecessor or successor.

Where Each One Wins

The NVIDIA GeForce RTX 4080 Mobile wins in every measurable performance category in the database. Its average benchmark score of 38135 versus 1184 for the Intel Arc B370 represents a decisive margin. The NVIDIA part's percentile placement at 81 versus 5 for the Intel part confirms that the RTX 4080 Mobile sits near the top of the database while the Arc B370 sits near the bottom.

The RTX 4080 Mobile's compute performance stands out. The Geekbench OpenCL score of 159575 and Geekbench Vulkan score of 145807 indicate strong general-purpose compute and modern graphics API performance. The PassMark G3D score of 24926 and GPU Compute score of 11191 reinforce this picture. The part handles DirectX 9, 10, 11, and 12 legacy workloads as shown by scores of 286, 157, 244, and 96 respectively, though these legacy tests show lower absolute numbers than the modern compute tests.

The Intel Arc B370 shows its best relative performance against its own nearest rivals. The delta of 1.4% ahead of the AMD FirePro M2000 indicates the Intel part leads that GPU, and its scores sit within 0.7% of the ATI Mobility Radeon HD 5570, ATI Radeon HD 5770, and AMD Radeon HD 7650M. For workloads that match those legacy parts, the Arc B370 delivers comparable results.

The Intel part's 25 W TDP versus 110 W for the NVIDIA part suggests the Arc B370 targets power-constrained environments, though the database does not include efficiency benchmarks. The Intel part's 300 MHz base clock and 2400 MHz boost clock show a wide clock range, indicating the part can scale down aggressively when idle and boost when needed.

The NVIDIA part's tensor cores, 232 of them, provide AI acceleration capability that the Intel part does not list. The RTX 4080 Mobile's 58 RT cores versus 10 for the Intel part indicates substantially stronger ray tracing throughput, though no ray tracing benchmarks appear in the database.

The Verdict

The data shows the NVIDIA GeForce RTX 4080 Mobile as the clear performance leader. Its average benchmark score of 38135 places it at the 81st percentile, while the Intel Arc B370's 1184 average score places it at the 5th percentile. The nearest rival data confirms the NVIDIA part competes with the RTX 4070 desktop GPU and sits within 0.6% of the RTX 5080 Mobile, while the Intel part competes with GPUs from the ATI Radeon HD and Mobility Radeon HD families.

For users who need maximum graphics throughput, the RTX 4080 Mobile delivers 24.72 TFLOPS FP32, 432.0 GB/s of memory bandwidth, and 12 GB of dedicated GDDR6 memory. The Intel Arc B370 delivers 6.144 TFLOPS FP32 and relies on System Shared memory with System Dependent bandwidth, a configuration that cannot match dedicated VRAM.

The RTX 4080 Mobile's 7424 shading units, 232 TMUs, and 80 ROPs dwarf the Intel part's 1280 shading units, 40 TMUs, and 20 ROPs. The NVIDIA part also brings 232 tensor cores and 58 RT cores, features that support AI and ray tracing workloads. The Intel part's 10 RT cores provide ray tracing capability but at a much smaller scale.

The Intel Arc B370's 25 W TDP versus 110 W for the NVIDIA part indicates a power efficiency advantage, but the database does not include efficiency benchmarks to quantify it. The Intel part's release date of 2026-01-26 makes it a newer product than the RTX 4080 Mobile's 2023-01-02 release, but newer does not translate into higher performance in the recorded data.

The verdict from the data is unambiguous: the NVIDIA GeForce RTX 4080 Mobile wins in every benchmark category recorded, and the Intel Arc B370 performs in a class reserved for legacy or entry-level parts. The only areas where the Intel part shows advantages are TDP, boost clock, and release date, none of which appear in the benchmark scores.
