AMD Radeon RX 7800M vs Intel Arc B370 Comparison

Head-to-Head Benchmarks

The recorded data contains a single direct comparison between the AMD Radeon RX 7800M and the Intel Arc B370. In the 3DMark Steel Nomad DX12 test, the AMD Radeon RX 7800M scores 2994 points, while the Intel Arc B370 scores 1184 points. This gives AMD a decisive 152.9% advantage in this workload, meaning the RX 7800M delivers more than 2.5 times the performance of the Arc B370 in this specific DX12 benchmark.

The breadth of the gap is substantial. The AMD part sits in the 73rd percentile of all GPUs in the database, whereas the Intel Arc B370 lands in the 5th percentile. The average benchmark score for the RX 7800M is 27883, compared to just 1184 for the Arc B370. That represents a roughly 23.5x difference in aggregate scoring across all recorded tests, though the Intel part only has a single benchmark entry in the database.

Looking at the nearest rivals for each card clarifies the positioning. The AMD Radeon RX 7800M scores 0.2% higher than the AMD Radeon Pro Vega 20 (27839), 0.3% lower than the AMD Radeon Pro W5500X (27973), 0.5% lower than the NVIDIA GeForce GTX 980 Ti (28020), and 0.8% lower than the AMD FirePro S7150 (28117). These delta values are all within one percentage point, indicating that the RX 7800M sits in a tightly contested performance band among older professional and enthusiast desktop parts.

The Intel Arc B370, by contrast, sits among much older hardware. It scores 0.2% below the ATI Mobility Radeon HD 5570 (1186), 0.5% below the ATI Radeon HD 5770 (1190), and 0.7% below the AMD Radeon HD 7650M (1192). Its only positive delta is 1.4% over the AMD FirePro M2000 (1168). These are legacy mobile and desktop parts from roughly a decade earlier, which puts the Arc B370's performance tier into sharp perspective.

The RX 7800M also shows a much richer benchmark profile. Beyond the Steel Nomad test, it records scores in Geekbench OpenCL (120778), Geekbench Vulkan (126668), Passmark DirectX 10 (99), DirectX 11 (176), DirectX 12 (89), DirectX 9 (174), G2D (892), G3D (17613), and GPU Compute (9342). The Arc B370 has no recorded scores in any of those tests, so the database cannot confirm how it behaves across those workloads. The single available data point, however, suggests a very large performance chasm in modern DX12 rendering.

Architecture Differences

The two GPUs come from entirely different architectural lineages. The AMD Radeon RX 7800M uses the Navi 32 chip built on RDNA 3.0 architecture, with the codename Wheat Nas. It belongs to the Navi Mobile (RX 7000M) generation within the Radeon RX 7000 series. The Intel Arc B370 uses the Panther Lake chip based on Xe3-LPG architecture, and it belongs to the Arc Graphics-M (Panther Lake) generation. The AMD part is fabricated by TSMC on a 5 nm process, while the Intel part uses Intel's own 3 nm process.

The transistor counts differ dramatically. The RX 7800M contains 28,100 million transistors on a 346 mm² die, giving a transistor density of 81.2 million per square millimeter. The Arc B370's transistor count and die size are listed as unknown in the database, so no direct comparison is possible on those fronts.

Memory architecture separates the two fundamentally. The RX 7800M has 12 GB of dedicated GDDR6 memory on a 192-bit bus, with 432.0 GB/s of bandwidth and a memory clock of 2250 MHz (18 Gbps effective). The Arc B370 uses system shared memory, with the bus width, type, and size all listed as system shared and bandwidth described as system dependent. This means the Intel part relies on the host system's memory rather than carrying its own dedicated VRAM.

Compute resources also differ substantially. The RX 7800M has 3840 shading units, 240 texture mapping units, 96 ROPs, and 60 ray tracing cores. The Arc B370 has 1280 shading units, 40 TMUs, 20 ROPs, and 10 ray tracing cores. The AMD part has exactly three times the shading units, six times the TMUs, and six times the ROPs of the Intel part. Ray tracing core count is six times higher on the AMD side as well.

Clock speeds show an interesting contrast. The RX 7800M has a base clock of 1295 MHz, a game clock of 2145 MHz, and a boost clock of 2335 MHz. The Arc B370 has a base clock of 300 MHz and a boost clock of 2400 MHz. The Intel part boosts slightly higher than the AMD part, but its base clock is far lower, and its render output is limited by the much smaller execution resource pool.

The production status for both is listed as active. The RX 7800M has a release date of September 10, 2024, while the Arc B370 has a release date of January 26, 2026. The RX 7800M lists Polaris Mobile as its predecessor, while the Arc B370 has no predecessor listed. Neither has a successor listed in the database.

The Verdict

The benchmark data presents a clear hierarchy. The AMD Radeon RX 7800M is the significantly faster GPU in the only recorded head-to-head test, the 3DMark Steel Nomad DX12 benchmark, with a 152.9% lead over the Intel Arc B370. That score places the RX 7800M in the 73rd percentile of all GPUs, while the Arc B370 sits at the 5th percentile. The average benchmark score gap of roughly 23.5x reinforces the performance stratification between the two.

The RX 7800M also carries a much larger hardware configuration: 12 GB of dedicated GDDR6 memory, 3840 shading units, 240 TMUs, 96 ROPs, and 60 ray tracing cores. It draws 180 W and uses no external power connectors according to the database, with a PCIe 4.0 x16 bus interface. The Arc B370, by contrast, draws 25 W, uses system shared memory, has 1280 shading units, 40 TMUs, 20 ROPs, and 10 ray tracing cores, and connects via an integrated graphics processor (IGP) bus interface.

The Arc B370's nearest rivals are all legacy parts from the ATI generation: the Mobility Radeon HD 5570, Radeon HD 5770, Radeon HD 7650M, and FirePro M2000. All of those comparisons fall within roughly one percentage point of the Arc B370. The RX 7800M's nearest rivals are the Radeon Pro Vega 20, Radeon Pro W5500X, GeForce GTX 980 Ti, and FirePro S7150, all within a single percentage point as well. The gap between these two rival clusters is enormous.

Pick the AMD Radeon RX 7800M for any workload that demands high DX12 rendering throughput, as its Steel Nomad score is more than double that of the Arc B370. Pick the Intel Arc B370 for scenarios where the 25 W thermal envelope and integrated design are the primary constraints, since its performance class is far below the RX 7800M but its power draw is only 25 W compared to 180 W.

Where Each One Wins

The AMD Radeon RX 7800M wins in every recorded benchmark category. Its 3DMark Steel Nomad DX12 score of 2994 is 152.9% higher than the Arc B370's 1184. It also holds the only recorded scores in Geekbench OpenCL, Geekbench Vulkan, and the full Passmark suite, meaning the database shows no workload where the Intel part outperforms it.

The RX 7800M's strengths are clearest in modern DX12 rendering, given its Steel Nomad result, and in general compute workloads where its 35.87 TFLOPS FP32 and FP16 throughput (at a 1:1 ratio) provide a large arithmetic advantage. Its 432.0 GB/s of dedicated memory bandwidth also supports high-resolution texture streaming and memory-intensive effects. The 73rd percentile ranking places it in the upper quarter of all GPUs in the database.

The Intel Arc B370's recorded strengths are limited to its power profile and integration characteristics. At 25 W TDP versus 180 W, it consumes a fraction of the power. Its IGP bus interface and system shared memory mean it requires no dedicated VRAM and no external power connectors, which suits compact portable devices. The boost clock of 2400 MHz is actually 65 MHz higher than the RX 7800M's 2335 MHz boost, though the much smaller execution resource pool prevents that clock advantage from translating into performance wins.

The Arc B370 also supports FP16 at 12.29 TFLOPS with a 2:1 ratio, which is higher than its FP32 rate and could benefit workloads that use mixed-precision arithmetic. Its 3 nm process node is more advanced than the 5 nm node of the RX 7800M, which contributes to its lower power draw. The 5th percentile ranking, however, shows that its overall performance class is near the bottom of the database.
