AMD Radeon RX 7400 vs Intel Arc B370 Comparison

Where Each One Wins

The recorded benchmark data shows a clear split in positioning between these two GPUs. The AMD Radeon RX 7400 is a discrete, dual-slot add-in card with a 43 W TDP, while the Intel Arc B370 is an integrated graphics processor (IGP) with a 25 W TDP. This fundamental difference drives where each part makes sense.

The AMD Radeon RX 7400 wins on every legacy and compute-oriented workload recorded in the database. In PassMark's DirectX 9 test, it scores 176 versus the Intel part's lack of any recorded score in that test. The same pattern holds for DirectX 10 (59 vs. no score), DirectX 11 (97 vs. no score), and DirectX 12 (44 vs. no score). The RX 7400 also posts a substantial PassMark G3D score of 11897 and a GPU compute score of 5152. Its PassMark G2D score is 1209.

The Intel Arc B370 wins the only head-to-head benchmark where both parts have recorded data. In 3DMark Steel Nomad DX12, the Intel part scores 1184 against the RX 7400's 1103, a delta of -6.8% from the AMD card's perspective. This means the Intel integrated solution outperforms the discrete AMD card in this specific modern DirectX 12 workload.

The wins distribution in the database is 0 for the AMD Radeon RX 7400 and 1 for the Intel Arc B370. However, the AMD card has a much larger benchmark footprint, with eight recorded tests versus just one for the Intel part. The average benchmark score reflects this breadth: 2467 for the RX 7400 versus 1184 for the Arc B370.

The percentile placement reinforces the gulf in overall performance. The RX 7400 sits at the 17th percentile among all GPUs, while the Arc B370 sits at the 5th percentile. For use-case selection, the RX 7400 provides broad legacy API support and compute throughput, while the Arc B370 delivers a competitive result in a single modern DX12 test.

Architecture Differences

The architectural split between these two parts is stark. The AMD Radeon RX 7400 uses the Navi 33 chip built on RDNA 3.0 architecture, with the codename Hotpink Bonefish. It belongs to the Navi III generation within the RX 7000 series. The silicon is fabricated on a 6 nm process at TSMC, containing 13,300 million transistors on a 204 mm² die, giving a transistor density of 65.2M per mm².

The Intel Arc B370 uses the Panther Lake chip built on Xe3-LPG architecture, belonging to the Arc Graphics-M (Panther Lake) generation. It is fabricated on a 3 nm process at Intel, though the transistor count and die size are recorded as unknown in the database.

The compute configurations differ significantly. The RX 7400 has 1792 shading units, 112 texture mapping units, and 64 raster operations pipelines. It includes 28 ray tracing cores. The Arc B370 has 1280 shading units, 40 TMUs, and 20 ROPs, with 10 ray tracing cores. The AMD part has a 2.8x advantage in TMU count and a 3.2x advantage in ROP count.

Clock behavior also differs. The RX 7400 runs at a base clock of 1452 MHz, a boost clock of 2300 MHz, and a game clock of 2200 MHz. Its memory clock is 2250 MHz with 18 Gbps effective. The Arc B370 has a much lower base clock of 300 MHz but a slightly higher boost clock of 2400 MHz. Its memory clock is recorded as "System Shared."

The memory subsystem is a major differentiator. The RX 7400 has 8 GB of dedicated GDDR6 memory on a 128-bit bus, delivering 288.0 GB/s of bandwidth. The Arc B370 uses system shared memory, with the bus width and bandwidth both dependent on the host system. This means the Intel part's memory performance is entirely contingent on the platform it is integrated into.

Rasterization and compute throughput numbers confirm the AMD card's advantage. The RX 7400 delivers 147.2 GPixel/s pixel rate, 257.6 GTexel/s texture rate, 16.49 TFLOPS FP32, and 32.97 TFLOPS FP16 (2:1). The Arc B370 delivers 48.00 GPixel/s, 96.00 GTexel/s, 6.144 TFLOPS FP32, and 12.29 TFLOPS FP16 (2:1). The AMD part is roughly 3x faster in pixel throughput, 2.7x in texture throughput, and 2.7x in FP32 compute.

Power and physical design diverge completely. The RX 7400 has a 43 W TDP, is dual-slot, requires a single 6-pin power connector, and suggests a 200 W power supply. It uses a PCIe 4.0 x8 bus interface. The Arc B370 has a 25 W TDP, is an IGP with no slot width, requires no power connectors, and has no suggested PSU. Its bus interface is IGP.

Both parts support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The RX 7400 offers display outputs of 1x HDMI 2.1a and 3x DisplayPort 2.1, while the Arc B370's display outputs are portable device dependent.

Head-to-Head Benchmarks

The only directly comparable benchmark in the database is 3DMark Steel Nomad DX12. In this test, the Intel Arc B370 scores 1184 against the AMD Radeon RX 7400's 1103. The delta percentage is -6.8%, indicating the AMD card trails by that margin. This is a notable result because the RX 7400 has substantially higher raw compute specifications, yet the Intel integrated part wins this modern DX12 workload.

The RX 7400's average benchmark score of 2467 is more than double the Arc B370's 1184. This average is derived from eight recorded tests for the AMD card, covering DirectX 9 through DirectX 12, G2D, G3D, and GPU compute workloads. The Intel part has only one recorded test.

In nearest-rival comparisons, the RX 7400 sits close to the AMD Radeon 8040S (2440 average, 1.1% delta), NVIDIA GeForce 710M (2433, 1.4%), Intel HD Graphics 610 (2425, 1.8%), and NVIDIA GeForce GT 710M (2422, 1.9%). These are all within roughly two percentage points, placing the RX 7400 in a tight cluster around the 2400-2500 average score range.

The Arc B370's nearest rivals are all much older parts. It sits 0.2% below the ATI Mobility Radeon HD 5570 (1186), 0.5% below the ATI Radeon HD 5770 (1190), 0.7% below the AMD Radeon HD 7650M (1192), and 1.4% above the AMD FirePro M2000 (1168). This places the Intel integrated solution in performance territory comparable to discrete GPUs from over a decade ago.

The RX 7400's individual PassMark scores show its strongest areas. The G3D score of 11897 dominates the average. The G2D score of 1209 indicates solid 2D performance. The DirectX 9 score of 176 is the highest among the DX tests, followed by DirectX 11 at 97, DirectX 10 at 59, and DirectX 12 at 44. The GPU compute score of 5152 suggests reasonable compute capability for the class.

The Arc B370's single recorded score of 1184 in Steel Nomad means the database cannot assess its legacy API performance. No DirectX 9, 10, 11, or compute scores exist for the Intel part. The only conclusion available is that it outperforms the RX 7400 in that one specific DX12 test.

The Verdict

The data directs a clear choice based on workload. The AMD Radeon RX 7400 is the broadly capable part. Its eight benchmark scores cover the full range of DirectX versions, 2D, 3D, and compute. Its average score of 2467 places it at the 17th percentile among all GPUs, well above the Arc B370's 5th percentile. For any application relying on legacy DirectX APIs, the RX 7400 is the only option with recorded performance, since the Arc B370 has no scores in those tests.

The Intel Arc B370 wins solely in the 3DMark Steel Nomad DX12 test, scoring 1184 versus 1103. This 6.8% advantage in a modern DX12 workload is meaningful, but it comes with significant caveats. The Arc B370 uses system shared memory, so its bandwidth is system dependent. Its nearest rivals are ATI Radeon HD 5770 and similar parts from the early 2010s. Its 6.144 TFLOPS FP32 and 48.00 GPixel/s pixel rate are far below the RX 7400's 16.49 TFLOPS and 147.2 GPixel/s.

For users needing a discrete, self-contained GPU with dedicated 8 GB GDDR6 memory, 288.0 GB/s bandwidth, and a PCIe 4.0 x8 interface, the RX 7400 is the appropriate choice. Its 43 W TDP and 200 W suggested PSU make it suitable for small form factor or low-power builds. The dual-slot design and 6-pin connector are standard requirements.

For ultra-low-power integrated graphics in a Panther Lake platform, the Arc B370 offers a competitive modern DX12 result at 25 W TDP with no power connectors. Its performance is system dependent due to shared memory, and its overall percentile ranking is low. The database shows it delivers a single strong result in Steel Nomad, but lacks the breadth of the RX 7400.

The release dates also inform the choice. The RX 7400 launched on August 7, 2025, while the Arc B370 launched on January 26, 2026. The Intel part is newer and its production status is listed as Active. The AMD card's production status is not recorded.

Neither part has a launch MSRP in the database, so no pricing information is available for comparison.
