AMD Radeon RX 7400 vs Intel Arc Pro B70 Comparison

Head-to-Head Benchmarks

The recorded data in the database contains a full benchmark suite for the AMD Radeon RX 7400, while the Intel Arc Pro B70 has no recorded benchmark scores at this time. This makes a direct numerical comparison of measured performance impossible. Instead, the comparison must rest on the architectural specifications and the AMD card's position within the database's ranking structure.

The AMD Radeon RX 7400 delivers a 3DMark Steel Nomad DX12 score of 1103. In PassMark tests, it records 176 in DirectX 9, 97 in DirectX 11, 59 in DirectX 10, and 44 in DirectX 12. Its PassMark G3D score sits at 11897, with a G2D score of 1209 and a GPU compute score of 5152. The average benchmark score across all recorded tests is 2467.

The RX 7400's closest rivals in the database, based on average score, are the AMD Radeon 8040S at 2440 (a 1.1% delta), the NVIDIA GeForce 710M at 2433 (1.4% delta), the Intel HD Graphics 610 at 2425 (1.8% delta), and the NVIDIA GeForce GT 710M at 2422 (1.9% delta). The RX 7400 holds a narrow lead over each of these, with the largest margin being 1.9% over the GT 710M. These are tight margins, indicating the RX 7400 sits in a specific performance tier rather than dominating its immediate neighbors.

The Intel Arc Pro B70, by contrast, has no recorded benchmark entries in the database. Its average benchmark score is listed as 0, and its nearest rivals list is empty. The database does record its percentile versus all GPUs at 50, which places it at the median of all tracked graphics cards. The RX 7400 sits at the 17th percentile, meaning it ranks below the majority of GPUs in the database. This percentile gap suggests the Intel card is expected to occupy a substantially higher performance tier, though no measured scores confirm this.

The RX 7400's raw compute figures provide context for its benchmark results. It delivers 16.49 TFLOPS of FP32 performance and 32.97 TFLOPS of FP16 (2:1 ratio). The Arc Pro B70 is specified for 22.94 TFLOPS FP32 and 45.88 TFLOPS FP16 (2:1 ratio). These figures indicate the Intel card carries roughly 39% more FP32 throughput on paper, a substantial gap that would likely translate into higher benchmark scores if measured.

Pixel and texture rates follow the same pattern. The RX 7400 produces 147.2 GPixel/s and 257.6 GTexel/s. The Arc Pro B70 produces 358.4 GPixel/s and 716.8 GTexel/s. The Intel card more than doubles the pixel throughput and nearly triples the texture rate. These are large architectural differences, not incremental ones.

Where Each One Wins

The RX 7400's recorded wins are in the direct benchmark measurements. It has measurable scores across all tested workloads, from legacy DirectX 9 to modern DX12, plus compute and 2D tests. Its strongest relative result is the PassMark G2D score of 1209, which indicates solid 2D performance for its tier. The DirectX 9 score of 176 is also notably higher than its DX11 and DX12 scores, suggesting the architecture handles older API workloads well. The GPU compute score of 5152 is over twice its average benchmark score, showing compute workloads are a relative strength.

The RX 7400 wins in power efficiency based on the specification data. Its TDP is 43 W with a suggested power supply of 200 W. It uses a single 6-pin connector. The Arc Pro B70 draws 230 W and requires a 550 W suggested power supply with a single 8-pin connector. In any scenario where power draw or thermal output matters, the RX 7400 has a decisive advantage. The database records no measured efficiency metric, but the TDP figures alone establish a clear separation.

The Arc Pro B70 wins on memory capacity and bandwidth. It carries 32 GB of GDDR6 on a 256-bit bus, yielding 608.0 GB/s of bandwidth. The RX 7400 has 8 GB of GDDR6 on a 128-bit bus, yielding 288.0 GB/s. The Intel card offers four times the capacity and more than double the bandwidth. For workloads that scale with memory footprint, such as large dataset rendering or high-resolution texturing, the B70 has a structural advantage.

The Arc Pro B70 also wins on raw throughput metrics. Its FP32, FP16, pixel rate, and texture rate all exceed the RX 7400 by wide margins. Its shading unit count of 4096 versus 1792, TMU count of 256 versus 112, and ROP count of 128 versus 64 all point to a larger execution engine. The B70 also has 32 ray tracing cores versus 28 on the RX 7400, a smaller relative advantage but still a lead.

The Intel card wins on process technology as well. It is built on TSMC's 5 nm node, while the RX 7400 uses TSMC's 6 nm node. The smaller node typically allows higher clock speeds and better density. The base clock of the B70 is 2280 MHz with a boost of 2800 MHz, compared to 1452 MHz base and 2300 MHz boost for the RX 7400. The Intel card's boost clock is 500 MHz higher.

The RX 7400 wins on transistor density when accounting for the die size disparity. The AMD chip packs 13,300 million transistors into 204 mm², giving a density of 65.2 million transistors per mm². The Intel chip's transistor count is listed as unknown, so no density calculation is possible from the recorded data. However, its die size is 368 mm², substantially larger than the RX 7400's 204 mm².

The Verdict

The data supports a clear split in use cases. The RX 7400 is the only card of the two with any measured benchmark results. Its average score of 2467 places it in the 17th percentile of all GPUs in the database, and its nearest rivals are all within 1.9% of its average score. This positions it as a low-power, entry-level tier card. Its 43 W TDP and 200 W suggested power supply make it suitable for systems with modest power delivery. The 8 GB memory capacity and 288.0 GB/s bandwidth are adequate for lighter workloads, and its DirectX 12 Ultimate and Vulkan 1.4 support indicate modern API compatibility.

The Arc Pro B70 has no measured scores, but its specifications place it in a different class entirely. The 50th percentile ranking, while not derived from measured scores, suggests the database expects it to sit at the median of all GPUs. Its 32 GB memory, 608.0 GB/s bandwidth, 22.94 TFLOPS FP32, and 2800 MHz boost clock all point to a high-end workstation or professional rendering card. The 230 W TDP and 550 W suggested power supply indicate a system designed for sustained heavy load.

For users constrained by power or thermal limits, the RX 7400 is the functional choice from the recorded data. It delivers measurable performance at 43 W and fits in a dual-slot form factor with a single 6-pin connector. Its 288.0 GB/s bandwidth and 8 GB memory handle standard resolutions and moderate detail settings.

For users who need large memory capacity, high bandwidth, or maximum compute throughput, the Arc Pro B70 is the clear pick based on specifications alone. The 32 GB memory is four times the RX 7400's capacity. The 608.0 GB/s bandwidth is more than double. The FP32 throughput is 39% higher. These are not marginal differences.

The RX 7400's DirectX 9 score of 176 and G2D score of 1209 suggest it handles legacy applications and desktop workloads competently. The Arc Pro B70's lack of any recorded benchmarks means no comparable legacy performance data exists. The B70's 32 ray tracing cores versus 28 on the RX 7400 gives it a slight edge in ray-traced workloads, but neither card has measured RT scores in the database.

The bus interface also differs. The RX 7400 uses PCIe 4.0 x8, while the Arc Pro B70 uses PCIe 5.0 x16. For systems with modern motherboards, the B70 has access to substantially more interconnect bandwidth. For older systems, the RX 7400's PCIe 4.0 x8 is broadly compatible.
