AMD Radeon RX 7900M vs Intel Arc B370 Comparison

AMD Radeon RX 7900M vs Intel Arc B370

Head-to-Head Benchmarks

The recorded database contains one direct comparison between these two mobile graphics solutions: the 3DMark Steel Nomad DX12 test. The AMD Radeon RX 7900M posts a score of 4201, while the Intel Arc B370 scores 1184. This produces a delta of 254.8% in favor of the AMD part, meaning the RX 7900M delivers roughly three and a half times the performance of the Arc B370 in this specific workload. That is a decisive margin, not a close contest.

The RX 7900M also has two additional benchmark results recorded in the database that the Arc B370 lacks. In Geekbench OpenCL, the AMD part scores 129499, and in Geekbench Vulkan it reaches 158760. The Arc B370 has no entries for either of those tests, so no direct comparison is possible there. The absence of additional Intel data points limits the overall picture, but the single head-to-head result is unambiguous: the AMD part wins the only shared test.

Looking at broader positioning, the RX 7900M sits at the 94th percentile among all GPUs in the database, while the Arc B370 sits at the 5th percentile. That gap in percentile rank is consistent with the raw score difference. The RX 7900M's average benchmark score across all recorded tests is 97487, whereas the Arc B370's average is 1184. The AMD part's nearest rivals in the database include the AMD Radeon Pro VII (average 97131, delta 0.4%), the NVIDIA Quadro RTX 6000 (average 101872, delta -4.3%), the AMD Radeon Instinct MI60 (average 92466, delta 5.4%), and the NVIDIA RTX A4500 (average 91671, delta 6.3%). These are all professional workstation-class GPUs, and the RX 7900M is within a few percentage points of each of them, slightly trailing the Quadro RTX 6000 but ahead of the others.

The Arc B370's nearest rivals are substantially older, lower-end parts. They include the ATI Mobility Radeon HD 5570 (average 1186, delta -0.2%), the ATI Radeon HD 5770 (average 1190, delta -0.5%), the AMD Radeon HD 7650M (average 1192, delta -0.7%), and the AMD FirePro M2000 (average 1168, delta 1.4%). The Arc B370 is essentially level with these legacy parts, within a percentage point either way. That places it in a completely different performance tier from the RX 7900M.

Where Each One Wins

The RX 7900M wins in every recorded scenario. It takes the sole head-to-head benchmark, and it holds a massive performance advantage. The data indicates this GPU is designed for demanding workloads, whether that involves high-resolution gaming, content creation, or compute tasks. Its 94th percentile ranking and proximity to workstation-class rivals like the NVIDIA Quadro RTX 6000 and AMD Radeon Pro VII suggest it can handle serious professional use cases without compromise.

The Arc B370 does not win any recorded benchmark. Its performance tier, as indicated by the 5th percentile ranking and its closeness to ATI HD 5000 and HD 7000 series parts, places it firmly in the entry-level segment. The data shows it is suitable for basic graphics output, light desktop work, and possibly older or less demanding games. It is not competitive with the RX 7900M in any measurable way according to the database.

For users who need maximum graphics throughput, the RX 7900M is the clear choice. For users who only need basic display functionality and minimal 3D performance, the Arc B370 can suffice, but it will not deliver a comparable experience. The recorded numbers leave no ambiguity about which GPU delivers higher performance.

Specification Differences

The two GPUs differ dramatically across nearly every hardware specification recorded in the database. The RX 7900M uses 16 GB of dedicated GDDR6 memory on a 256-bit bus, providing 576.0 GB/s of memory bandwidth. The Arc B370 uses system shared memory, with bus width and bandwidth listed as system dependent. That means the Intel part relies on the host system's memory configuration, while the AMD part has its own dedicated pool.

Clock speeds also diverge sharply. The RX 7900M has a base clock of 1825 MHz and a boost clock of 2090 MHz. The Arc B370 has a base clock of 300 MHz and a boost clock of 2400 MHz. While the Intel part boosts higher, the AMD part sustains a much higher base frequency, and the architectural differences render raw clock comparison secondary.

Compute units and pixel processing show the scale of the gap. The RX 7900M has 4608 shading units, 288 texture mapping units (TMUs), and 192 raster operation units (ROPs). The Arc B370 has 1280 shading units, 40 TMUs, and 20 ROPs. The RX 7900M also has 72 ray tracing cores, while the Arc B370 has 10. Pixel rate for the RX 7900M is 401.3 GPixel/s versus 48.00 GPixel/s for the Arc B370. Texture rate is 601.9 GTexel/s versus 96.00 GTexel/s.

Floating point performance follows the same pattern. The RX 7900M delivers 38.52 TFLOPS FP32 and 77.05 TFLOPS FP16 (2:1). The Arc B370 delivers 6.144 TFLOPS FP32 and 12.29 TFLOPS FP16 (2:1). That is roughly a 6.3x difference in FP32 throughput, though the exact ratio depends on the workload.

Power consumption differs enormously. The RX 7900M has a TDP of 180 W, while the Arc B370 has a TDP of 25 W. Both are integrated into mobile platforms with no power connectors listed and portable device dependent display outputs. The RX 7900M uses a PCIe 4.0 x16 bus interface, while the Arc B370 uses an IGP bus interface, meaning it is integrated into the processor package rather than a discrete add-in.

Both GPUs support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Both have IGP slot width and no external power connectors. The RX 7900M is listed as using a 5 nm process from TSMC, while the Arc B370 uses a 3 nm process from Intel. Transistor count and die size are known for the AMD part (57,700 million transistors, 529 mm² die) but unknown for the Intel part.

Architecture Differences

The RX 7900M is built on the RDNA 3.0 architecture, specifically the Navi 31 chip with the codename Plum Bonito. It belongs to the Navi Mobile (RX 7000M) generation and the Radeon RX 7000 series. The Arc B370 uses the Xe3-LPG architecture on the Panther Lake chip, belonging to the Arc Graphics-M (Panther Lake) generation. These are fundamentally different GPU designs targeting different market segments.

The process nodes reflect the generational difference. The RX 7900M uses a 5 nm process from TSMC, while the Arc B370 uses a 3 nm process from Intel. The Intel part's smaller process node does not translate into performance advantage given the massive difference in chip scale. The RX 7900M has 57,700 million transistors on a 529 mm² die, with a transistor density of 109.1M per mm². The Arc B370's transistor count and die size are not recorded in the database.

Architecture features differ in several key areas. The RX 7900M has 4608 shading units, 288 TMUs, 192 ROPs, and 72 ray tracing cores. The Arc B370 has 1280 shading units, 40 TMUs, 20 ROPs, and 10 ray tracing cores. The RX 7900M's memory subsystem is dedicated GDDR6 with 16 GB capacity and 576.0 GB/s bandwidth. The Arc B370 relies on system shared memory, which means its performance depends heavily on the host platform's memory configuration.

The RX 7900M is a discrete GPU with a PCIe 4.0 x16 interface. The Arc B370 is an integrated GPU with no dedicated bus interface, sharing system resources. This architectural distinction explains much of the performance difference. A discrete GPU with dedicated memory and a wide bus has inherent advantages over an integrated solution sharing bandwidth with the CPU.

The RX 7900M's predecessor is listed as Polaris Mobile, while the Arc B370 has no predecessor recorded. The RX 7900M released on 2023-10-18, and the Arc B370 released on 2026-01-26, so the Intel part is newer but does not outperform the older AMD design. Both are marked as Active in production status.

The Verdict

The data supports a straightforward choice. The AMD Radeon RX 7900M is in a completely different performance class than the Intel Arc B370. The 254.8% delta in the 3DMark Steel Nomad DX12 test is the only direct comparison, and it is overwhelmingly in favor of AMD. The RX 7900M's 94th percentile ranking versus the Arc B370's 5th percentile ranking reinforces that gap.

Users who require high graphics performance, whether for gaming, rendering, or compute workloads, should choose the RX 7900M. Its 16 GB of dedicated GDDR6 memory, 576.0 GB/s bandwidth, 38.52 TFLOPS FP32 throughput, and 72 ray tracing cores provide the resources needed for demanding applications. Its average benchmark score of 97487 places it alongside professional workstation GPUs, indicating it can handle serious workloads.

Users who only need basic graphics output from an integrated solution can consider the Arc B370. Its 25 W TDP and system shared memory make it a low-power option suitable for portable devices with modest graphics demands. Its average benchmark score of 1184 and proximity to decade-old ATI parts indicate it is not built for intensive 3D work.

There are no recorded scenarios where the Arc B370 wins against the RX 7900M. The Intel part may have advantages in power consumption and integration simplicity, but those are not reflected in benchmark wins. For anyone prioritizing graphics performance, the RX 7900M is the only choice supported by the recorded data. The Arc B370 exists in a fundamentally different performance tier, and no amount of architectural recency changes that measured outcome.
