Intel Arc B370 vs NVIDIA GeForce RTX 4080 Max-Q Comparison

Intel Arc B370 is an integrated graphics processor built on Intel's 3 nm Panther Lake chip, using the Xe3-LPG architecture and designed for the Arc Graphics-M (Panther Lake) generation. NVIDIA GeForce RTX 4080 Max-Q is a discrete mobile GPU from the GeForce 40-series, built on TSMC's 5 nm process with the Ada Lovelace architecture and the AD104 chip. The database contains a single benchmark result for the Arc B370 (3DMark Steel Nomad DX12, score 1184) and no recorded benchmark scores for the RTX 4080 Max-Q, so the comparison relies on the Arc B370's measured performance, its percentile ranking, and the fully specified hardware characteristics of both parts.

Where Each One Wins

The recorded data shows that the Arc B370 has exactly one benchmark entry: 3DMark Steel Nomad DX12, where it scores 1184 points. That score places it in the 5th percentile of all GPUs in the database, which indicates that its measured performance is in the lower range of the overall distribution. Its nearest rivals in the database are all older or lower-end parts: ATI Mobility Radeon HD 5570 (avg score 1186, delta -0.2%), ATI Radeon HD 5770 (avg score 1190, delta -0.5%), AMD Radeon HD 7650M (avg score 1192, delta -0.7%), and AMD FirePro M2000 (avg score 1168, delta +1.4%). The Arc B370 is effectively tied with these parts, sitting within 1.4% of each of them, and it is slightly ahead of only the AMD FirePro M2000.

For the RTX 4080 Max-Q, the database contains no benchmark scores, no average score, and no nearest rivals. Its percentileVsAllGpus is 50, which is the median position, but this percentile is assigned without any measured benchmark data in the pack. The absence of scores means that the RTX 4080 Max-Q cannot be said to win any direct benchmark comparison from the recorded measurements. However, the hardware specification differences are substantial and point to a large performance gap in compute and memory capabilities.

The Arc B370 wins in the category of power efficiency and integration. Its TDP is 25 W, compared to 60 W for the RTX 4080 Max-Q. It also has a base clock of 300 MHz and a boost clock of 2400 MHz, while the RTX 4080 Max-Q has a base clock of 795 MHz and a boost clock of 1350 MHz. The Arc B370's higher boost clock, combined with its much lower power draw, suggests that it is designed for lightweight, portable devices where sustained low-power operation is a priority. The RTX 4080 Max-Q, with its 60 W TDP, is positioned for higher performance in thicker laptops that can manage more heat and power.

The RTX 4080 Max-Q wins in every raw compute and memory specification. It has 7424 shading units, 232 TMUs, 80 ROPs, 58 RT cores, and 232 tensor cores, versus 1280 shading units, 40 TMUs, 20 ROPs, and 10 RT cores for the Arc B370. Its FP32 throughput is 20.04 TFLOPS, and its FP16 throughput is also 20.04 TFLOPS (1:1), whereas the Arc B370 delivers 6.144 TFLOPS FP32 and 12.29 TFLOPS FP16 (2:1). The RTX 4080 Max-Q has 12 GB of GDDR6 memory on a 192-bit bus with 432.0 GB/s of bandwidth, while the Arc B370 uses system shared memory with system dependent bandwidth. The pixel rate is 108.0 GPixel/s versus 48.00 GPixel/s, and the texture rate is 313.2 GTexel/s versus 96.00 GTexel/s.

The Verdict

The data indicates that the RTX 4080 Max-Q is the overwhelmingly more capable part in terms of hardware specifications, but the lack of any benchmark score for it in the database prevents a direct measured comparison. The Arc B370 has a recorded score of 1184 in 3DMark Steel Nomad DX12, which places it at the 5th percentile, meaning it sits near the bottom of the performance distribution for all GPUs tracked. The RTX 4080 Max-Q, with its 50th percentile ranking, is positioned at the median, but this ranking is not backed by any recorded benchmark in the pack, so it should be interpreted as a classification rather than a measured result.

For users who rely on benchmark data, the Arc B370 is the only part with a verifiable score. Its performance is comparable to integrated and older discrete GPUs from the early 2010s, such as the ATI Mobility Radeon HD 5570 and the AMD Radeon HD 7650M, which all cluster around the 1184 to 1192 range. The RTX 4080 Max-Q, based on its specifications, is in a different performance class entirely: it has 5.8 times the shading units, 3.26 times the FP32 throughput, and 432.0 GB/s of dedicated memory bandwidth versus the Arc B370's system dependent shared memory.

The verdict from the data is clear: the Arc B370 is a low-power integrated solution for basic 3D workloads, while the RTX 4080 Max-Q is a high-performance mobile GPU for demanding applications. The RTX 4080 Max-Q should be selected for tasks that require high shader throughput, ray tracing, tensor operations, and large dedicated memory pools. The Arc B370 should be selected for systems where a 25 W power envelope and integrated design are mandatory, and where the expected workload is light enough to match the performance level of its nearest rivals. The absence of RTX 4080 Max-Q benchmark scores means that any direct performance comparison is speculative, but the specification gap is so wide that the outcome is not in doubt from a hardware capability standpoint.

The RTX 4080 Max-Q has a base clock of 795 MHz and a boost clock of 1350 MHz, plus a memory clock of 2250 MHz (18 Gbps effective). Memory configuration also diverges: the Arc B370 uses system shared memory with system dependent bandwidth, while the RTX 4080 Max-Q has 12 GB of GDDR6 on a 192-bit bus with 432.0 GB/s of bandwidth.

Compute unit counts are massively different. The Arc B370 has 1280 shading units, 40 TMUs, 20 ROPs, and 10 RT cores. The RTX 4080 Max-Q has 7424 shading units, 232 TMUs, 80 ROPs, 58 RT cores, and 232 tensor cores. The Arc B370 has no listed tensor cores, while the RTX 4080 Max-Q has 232.

Throughput figures differ by multiples. The Arc B370 delivers 48.00 GPixel/s pixel rate, 96.00 GTexel/s texture rate, 6.144 TFLOPS FP32, and 12.29 TFLOPS FP16 (2:1).

Architecture Differences

The two GPUs come from different architectural lineages. The Arc B370 is based on Intel's Xe3-LPG architecture, which is part of the Arc Graphics-M (Panther Lake) generation. The chip is named Panther Lake, and it is fabricated on a 3 nm process at Intel's foundry. The RTX 4080 Max-Q is based on NVIDIA's Ada Lovelace architecture, using the AD104 chip, and belongs to the GeForce 40 Mobile generation. It is fabricated on a 5 nm process at TSMC.

The core feature sets differ in important ways. The Arc B370 has 10 ray tracing cores and no tensor cores listed. The RTX 4080 Max-Q has 58 ray tracing cores and 232 tensor cores, which indicates a dedicated hardware path for ray tracing and AI-accelerated workloads that the Arc B370 does not match. The FP16 throughput also reveals a difference in execution strategy: the Arc B370 achieves 12.29 TFLOPS FP16 via a 2:1 ratio relative to FP32, while the RTX 4080 Max-Q achieves 20.04 TFLOPS FP16 at a 1:1 ratio, meaning it has full-rate FP16 execution across its shader units.

Memory architecture is fundamentally different. The Arc B370 relies on system shared memory, with no dedicated VRAM, no fixed bus width, and bandwidth that is system dependent. The RTX 4080 Max-Q uses 12 GB of GDDR6 on a 192-bit bus with a fixed 432.0 GB/s bandwidth. This gives the RTX 4080 Max-Q a deterministic memory performance profile, while the Arc B370's memory performance varies with the host system's RAM configuration.

Both GPUs support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so the API feature set is identical at the specification level. However, the underlying hardware capabilities, particularly the RT core count and the presence of tensor cores on the RTX 4080 Max-Q, suggest that feature-heavy workloads will scale very differently. The Arc B370's 10 RT cores are present but limited, whereas the RTX 4080 Max-Q's 58 RT cores and 232 tensor cores provide a much larger parallel infrastructure for those specialized operations.

Head-to-Head Benchmarks

There are no head-to-head benchmark entries in the database for these two GPUs. The headToHeadBenchmarks array is empty, and the winsA and winsB counters are both 0. The only measured score belongs to the Arc B370: 1184 in 3DMark Steel Nomad DX12. The RTX 4080 Max-Q has no recorded scores, so a direct benchmark-by-benchmark comparison is not possible from the recorded data.

What the data does allow is a comparison of the Arc B370's measured score against its nearest rivals. The Arc B370's 1184 is 0.2% below the ATI Mobility Radeon HD 5570's 1186, 0.5% below the ATI Radeon HD 5770's 1190, and 0.7% below the AMD Radeon HD 7650M's 1192. It is 1.4% above the AMD FirePro M2000's 1168. These deltas show that the Arc B370 is statistically clustered with those older parts, and its 5th percentile ranking confirms that it sits at the low end of the database's GPU performance distribution.

For the RTX 4080 Max-Q, the absence of benchmark data means that its 50th percentile ranking is the only performance-related figure, and it comes without any supporting score. The specification comparison, however, provides a clear picture of the magnitude of the difference. The RTX 4080 Max-Q has 3.26 times the FP32 throughput (20.04 TFLOPS vs 6.144 TFLOPS), 2.25 times the pixel rate (108.0 GPixel/s vs 48.00 GPixel/s), and 3.26 times the texture rate (313.2 GTexel/s vs 96.00 GTexel/s). It has 5.8 times the shading units and 5.8 times the RT cores.

The largest single-specification gap is in memory bandwidth. The RTX 4080 Max-Q's 432.0 GB/s is a fixed, dedicated figure, while the Arc B370's bandwidth is listed as system dependent with no numeric value. Even if the Arc B370's shared memory could reach high bandwidth in a best-case system, the RTX 4080 Max-Q's dedicated 12 GB GDDR6 pool removes any dependency on system RAM performance. The recorded data therefore supports the conclusion that the RTX 4080 Max-Q is designed for a much higher performance tier, and the Arc B370's 3DMark Steel Nomad score of 1184 is consistent with its low percentile placement and its proximity to decade-old mobile and desktop parts.
