AMD Radeon RX 7400 OEM vs Intel Arc Pro B70 Comparison

Where Each One Wins

The recorded database contains no head-to-head benchmark entries for the AMD Radeon RX 7400 OEM against the Intel Arc Pro B70. With zero wins recorded for either side, the measured performance comparison is undefined. The AMD part carries a 50th percentile ranking among all GPUs, and the Intel part also sits at the 50th percentile. Neither card has an average benchmark score entered into the database, so no direct frame-rate or compute-score advantage can be attributed to either product from the available measurements.

The AMD Radeon RX 7400 OEM delivers 7.885 TFLOPS of FP32 compute, while the Intel Arc Pro B70 delivers 22.94 TFLOPS. In raw shading throughput, the Intel card computes at roughly three times the rate of the AMD card. Pixel fill rates follow the same pattern: the Intel part renders 358.4 GPixel/s versus 70.40 GPixel/s for the AMD part, a factor of about five. Texture fill rates show 716.8 GTexel/s for Intel versus 123.2 GTexel/s for AMD, again a substantial gap. These figures indicate that the Intel Arc Pro B70 dominates in any workload that scales with shader count, texture units, or raster output units.

The AMD card counters with a dramatically lower thermal envelope. Its TDP of 55 W compares to 230 W for the Intel card. The AMD card uses a single-slot cooler and a single 6-pin power connector, while the Intel card requires a dual-slot cooler and an 8-pin connector. The suggested power supply for the AMD card is 250 W; the Intel card asks for 550 W. For systems constrained by power delivery or chassis space, the AMD Radeon RX 7400 OEM presents the only viable option in this pairing.

Memory capacity and bandwidth split decisively toward Intel. The Intel Arc Pro B70 carries 32 GB of GDDR6 on a 256-bit bus, yielding 608.0 GB/s of bandwidth. The AMD Radeon RX 7400 OEM has 8 GB of GDDR6 on a 128-bit bus, yielding 172.8 GB/s. The Intel memory subsystem offers 3.5 times the bandwidth and four times the capacity. Workloads that fit within 8 GB may run on either card, but larger datasets, high-resolution textures, or multi-model inference scenarios will require the Intel memory footprint.

Architecture Differences

The two GPUs come from different architectural generations and design philosophies. The AMD Radeon RX 7400 OEM uses the Navi 33 chip built on RDNA 3.0 architecture, codenamed Hotpink Bonefish. The process node is 6 nm at TSMC, with 13,300 million transistors on a 204 mm² die. The transistor density computes to 65.2 million per square millimeter. The Intel Arc Pro B70 uses the BMG-G31 chip built on Xe2-HPG architecture from the Battlemage (Pro Series) generation. The process node is 5 nm at TSMC, with a die size of 368 mm² and an unknown transistor count.

Shader resources differ significantly. The AMD card has 1,792 shading units, 112 TMUs, and 64 ROPs, with 28 ray tracing cores. The Intel card has 4,096 shading units, 256 TMUs, and 128 ROPs, with 32 ray tracing cores. The Intel part doubles or nearly doubles every execution resource category. The AMD card achieves 7.885 TFLOPS of FP32 and the same 7.885 TFLOPS for FP16, a 1:1 ratio that indicates no dedicated half-precision acceleration. The Intel card reaches 22.94 TFLOPS FP32 and 45.88 TFLOPS FP16, a 2:1 ratio showing dedicated FP16 throughput.

Clock behavior differs as well. The AMD card has a base clock of 330 MHz and a boost clock of 1100 MHz, with memory running at 1350 MHz (10.8 Gbps effective). The Intel card has a base clock of 2280 MHz and a boost clock of 2800 MHz, with memory at 2375 MHz (19 Gbps effective). The Intel clocks run much higher, contributing to its compute advantage despite the architectural differences.

Interface and physical design diverge. The AMD card uses PCIe 4.0 x8, while the Intel card uses PCIe 5.0 x16. The AMD card measures 167 mm in length (6.6 inches) with no recorded height or width. The Intel card measures 267 mm in length (10.5 inches), 110 mm in height (4.3 inches), and 39 mm in width (1.5 inches). Both cards support the same display outputs: 1x HDMI 2.1a and 3x DisplayPort 2.1. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

The Verdict

The database shows two GPUs with no direct benchmark comparison, so any selection must rely on the recorded specification data. The Intel Arc Pro B70 is the superior compute and rendering device by every measured throughput metric. It delivers 2.9 times the FP32 throughput, 5.1 times the pixel fill rate, 5.8 times the texture fill rate, four times the memory capacity, and 3.5 times the memory bandwidth of the AMD Radeon RX 7400 OEM. Its 32 ray tracing cores exceed the AMD card's 28, and its dual-slot cooler with 8-pin power indicates a design built for sustained high-load operation.

The AMD Radeon RX 7400 OEM fits a completely different role. Its 55 W TDP, single-slot profile, 167 mm length, and 250 W suggested power supply make it appropriate for small-form-factor or low-power systems where the Intel card cannot physically or electrically fit. The AMD card uses PCIe 4.0 x8, which suits motherboards without PCIe 5.0 support, while the Intel card requires PCIe 5.0 x16 for full interface bandwidth. The AMD card has no launch MSRP recorded, while the Intel card carries a launch MSRP of 949 USD.

For any workload where performance matters more than power draw or physical size, the Intel Arc Pro B70 is the clear choice. For embedded, compact, or power-limited deployments where the workload fits within 8 GB of VRAM and modest compute demands, the AMD Radeon RX 7400 OEM is the only option in this pairing. The data does not support any scenario where the AMD card outperforms the Intel card in raw throughput, but the AMD card's power efficiency and compact dimensions are unmatched by the Intel part.

Head-to-Head Benchmarks

The database lists no head-to-head benchmark results between the AMD Radeon RX 7400 OEM and the Intel Arc Pro B70. The winsA and winsB counters are both zero, and the headToHeadBenchmarks array is empty. This absence of measured data means no direct comparison of frame rates, render times, or synthetic scores can be drawn from the recorded information. The only quantitative comparison available comes from the specification fields.

The largest recorded advantage for the Intel card appears in texture fill rate. The Intel Arc Pro B70 reaches 716.8 GTexel/s, which is 5.8 times the AMD card's 123.2 GTexel/s. Pixel fill rate shows a 5.1 times advantage for Intel (358.4 GPixel/s versus 70.40 GPixel/s). Memory bandwidth gives Intel a 3.5 times lead (608.0 GB/s versus 172.8 GB/s). FP32 compute gives Intel a 2.9 times lead (22.94 TFLOPS versus 7.885 TFLOPS). FP16 compute gives Intel a 5.8 times lead (45.88 TFLOPS versus 7.885 TFLOPS), since the Intel card doubles its FP32 rate in half precision while the AMD card maintains a 1:1 ratio.

The AMD card shows its only numerical advantages in power consumption, physical size, and clock strategy. The AMD TDP of 55 W is 23.9 percent of the Intel TDP of 230 W. The AMD card's 167 mm length is 62.5 percent of the Intel card's 267 mm length. The AMD card's base clock of 330 MHz is far lower than the Intel base clock of 2280 MHz, and the AMD boost clock of 1100 MHz is below the Intel boost clock of 2800 MHz, indicating that the AMD part relies on a lower-power operating envelope rather than high clock speeds.

The AMD card's FP32 and FP16 performance are equal at 7.885 TFLOPS, whereas the Intel card achieves 45.88 TFLOPS FP16 against 22.94 TFLOPS FP32. This means for half-precision workloads, the Intel card widens its advantage further. The Intel card uses 4,096 shading units to reach its throughput, while the AMD card uses 1,792. The Intel card's 256 TMUs and 128 ROPs likewise outnumber the AMD card's 112 TMUs and 64 ROPs.
