Architecture Differences

The two GPUs come from different architectural lineages. AMD 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 Radeon RX 7000 series. Intel uses the BMG-G21 chip built on Xe2-HPG architecture, belonging to the Battlemage generation within the Arc 5 series.

Manufacturing processes differ notably. The AMD chip uses a 6 nm process at TSMC, while the Intel chip uses a 5 nm process, also at TSMC. Transistor counts show Intel's chip is substantially larger: 19,600 million transistors versus 13,300 million for AMD. Die sizes follow the same pattern, with the Intel die at 272 mm² versus 204 mm² for AMD. Transistor density favors Intel at 72.1 million per mm² versus 65.2 million per mm² for AMD.

Compute resources differ significantly. The Intel card has 2560 shading units, 160 texture mapping units, and 80 render output units. The AMD card has 1792 shading units, 112 TMUs, and 64 ROPs. Ray tracing cores also differ, with AMD featuring 28 RT cores compared to Intel's 20. Neither card lists tensor cores in the database.

Clock behavior reveals a striking difference in design philosophy. The AMD Radeon RX 7400 OEM runs at only 330 MHz base and 1100 MHz boost, extremely low figures that suggest heavy power limiting or a specialized OEM configuration. The Intel Arc B580 runs at 2670 MHz for both base and boost. Despite the massive clock disparity, the AMD card still achieves 7.885 TFLOPS FP32 performance, while the Intel card reaches 13.67 TFLOPS FP32. The Intel card also supports FP16 at 27.34 TFLOPS with a 2:1 ratio, while the AMD card does FP16 at 7.885 TFLOPS with a 1:1 ratio.

Rasterization throughput numbers reflect the compute difference. The Intel card achieves a pixel rate of 213.6 GPixel/s and a texture rate of 427.2 GTexel/s. The AMD card achieves 70.40 GPixel/s and 123.2 GTexel/s. These figures show the Intel card delivering approximately three times the pixel throughput and 3.5 times the texture throughput of the AMD card.

Both cards support the same API set: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Both use a PCIe 4.0 x8 bus interface, and both offer identical display outputs: one HDMI 2.1a port and three DisplayPort 2.1 ports.

The Verdict

The recorded data shows the Intel Arc B580 as the clearly superior performer. Its 13.67 TFLOPS FP32 output, 456.0 GB/s memory bandwidth, and 68th percentile ranking position it as a capable mainstream graphics card. Its nearest rivals, all within 1% in average score, include the RTX 2080 and RTX 3080 from NVIDIA, which were flagship cards in their respective generations. This suggests the Arc B580 competes at a level far above entry-class hardware.

The AMD Radeon RX 7400 OEM occupies a different position entirely. Its 50th percentile ranking places it at the median of all GPUs, and its specifications suggest a low-power, space-constrained design. The 55 W TDP, single-slot footprint, and 167 mm length indicate a card intended for prebuilt systems or compact OEM chassis where power and space are limited. The extremely low 330 MHz base clock suggests the card is heavily power-limited in its default configuration.

The data does not support direct head-to-head performance statements because no benchmark results exist for the AMD card in the database. However, the compute resource disparity is substantial. The Intel card has 43% more shading units, 43% more TMUs, 25% more ROPs, and 73% higher FP32 throughput. It also has 50% more memory capacity and 164% more memory bandwidth. These architectural advantages would logically translate to significantly higher frame rates in most workloads.

For users who need maximum performance, the Intel Arc B580 is the appropriate choice based on the data. For systems requiring minimal power draw, compact dimensions, and single-slot installation, the AMD Radeon RX 7400 OEM fits those constraints with its 55 W TDP and 167 mm length.

Where Each One Wins

The Intel Arc B580 wins decisively in raw compute performance. Its FP32 output of 13.67 TFLOPS, texture rate of 427.2 GTexel/s, and pixel rate of 213.6 GPixel/s establish it as the superior card for gaming and general graphics workloads. The 12 GB memory capacity and 456.0 GB/s bandwidth provide substantial headroom for modern game assets and high-resolution textures. The card's 68th percentile ranking and average score of 23021, which places it within 1% of the RTX 2080 and RTX 3080, indicate it delivers high-end performance in its price class.

The Arc B580 also wins in memory-intensive scenarios. Its 192-bit bus and 19 Gbps effective memory speed produce more than 2.6 times the bandwidth of the AMD card. This advantage matters for workloads that stream large amounts of data, such as 4K texture sets or compute tasks with large working sets. The FP16 throughput of 27.34 TFLOPS, double the FP32 rate, gives the Intel card an advantage in workloads that can use reduced precision.

The AMD Radeon RX 7400 OEM wins in power efficiency and physical footprint. Its 55 W TDP is roughly 29% of the Intel card's 190 W TDP. The suggested PSU requirement of 250 W versus 450 W reflects this lower power draw. The single-slot design and 167 mm length allow installation in compact chassis where the Intel card's 272 mm dual-slot design would not fit. The AMD card requires only a single 6-pin power connector, while the Intel card needs an 8-pin connector.

The AMD card also wins in transistor efficiency relative to its power budget. Despite having fewer transistors (13,300 million versus 19,600 million) on a larger process node (6 nm versus 5 nm), it achieves a 50th percentile ranking while drawing less than a third of the power. The 28 RT cores versus Intel's 20 provide a higher ray tracing core count, though the overall compute advantage of the Intel card may offset this in actual ray tracing workloads.

For system builders constrained by power supply capacity or chassis space, the AMD card presents the only viable option between these two. For anyone building a gaming system with standard case dimensions and a 450 W or higher PSU, the Intel card's performance advantages across every compute metric make it the stronger choice. The database shows no scenario where the AMD card outperforms the Intel card in measured performance, but its existence in the market serves systems where the Intel card simply cannot be installed.
