Analysis: AMD Radeon RX 7400 OEM vs Intel Arc B370

Head-to-Head Benchmarks

The recorded data shows that the AMD Radeon RX 7400 OEM and the Intel Arc B370 occupy very different performance tiers, with the RX 7400 OEM holding a clear advantage in raw compute throughput. The RX 7400 OEM delivers 7.885 TFLOPS of FP32 performance, while the Arc B370 manages 6.144 TFLOPS. That is a 28.3% lead for the AMD part in single-precision floating-point work. In FP16 compute, the tables turn somewhat: the Arc B370 outputs 12.29 TFLOPS using a 2:1 ratio, while the RX 7400 OEM matches its FP32 figure at 7.885 TFLOPS with a 1:1 ratio. The Intel part is 55.8% ahead in half-precision throughput, which indicates a strong advantage for workloads that can exploit packed math.

The texture and pixel throughput numbers highlight another gap. The RX 7400 OEM reaches 123.2 GTexel/s and 70.40 GPixel/s, whereas the Arc B370 posts 96.00 GTexel/s and 48.00 GPixel/s. The AMD card is 28.3% faster in texture fill and 46.7% faster in pixel fill. These figures align with the shading unit and ROP counts: the RX 7400 OEM carries 1792 shading units, 112 TMUs, and 64 ROPs, against the Arc B370's 1280 shading units, 40 TMUs, and 20 ROPs. The ROP disparity is particularly stark, with the AMD part offering 3.2 times the pixel output capability.

In the only recorded 3DMark Steel Nomad DX12 benchmark, the Arc B370 scores 1184. Its nearest rivals in the database are older parts: the ATI Mobility Radeon HD 5570 at 1186 (0.2% ahead), the ATI Radeon HD 5770 at 1190 (0.5% ahead), and the AMD Radeon HD 7650M at 1192 (0.7% ahead). The AMD FirePro M2000 trails at 1168, which is 1.4% behind the Arc B370. This places the Arc B370 at the 5th percentile among all GPUs in the database, meaning 95% of recorded graphics processors score higher. The RX 7400 OEM sits at the 50th percentile, though it has no recorded benchmark scores or nearest rivals in the database. The performance gap between the two is substantial based on the architectural specifications alone.

Where Each One Wins

The AMD Radeon RX 7400 OEM wins in scenarios that demand high FP32 throughput, high texture fill, and high pixel output. Its 7.885 TFLOPS FP32 rating, 123.2 GTexel/s texture rate, and 70.40 GPixel/s pixel rate make it the stronger choice for traditional rasterization workloads, such as gaming at conventional resolutions and general-purpose compute that relies on single-precision math. The 8 GB of dedicated GDDR6 memory on a 128-bit bus with 172.8 GB/s of bandwidth gives it a fixed, local memory pool that does not compete with system resources. The 28 RT cores also provide hardware ray tracing capability, which the Arc B370 supports with 10 RT cores.

The Intel Arc B370 wins in efficiency and FP16-heavy tasks. Its 25 W TDP is less than half of the RX 7400 OEM's 55 W TDP, making it the lower-power option. The 12.29 TFLOPS FP16 output, achieved with a 2:1 ratio, doubles its FP32 rate and gives it an advantage in workloads that use half-precision arithmetic, such as certain AI inference or image processing routines. The Arc B370 also operates as an integrated graphics processor (IGP), requiring no power connectors and using system shared memory, which suits portable devices where a discrete card is not feasible. Its boost clock of 2400 MHz is more than double the RX 7400 OEM's 1100 MHz boost, though the AMD part's higher base clock of 330 MHz versus 300 MHz shows a narrower idle-to-active gap.

For memory-bound tasks, the RX 7400 OEM has a definitive edge with its dedicated 172.8 GB/s bandwidth. The Arc B370's bandwidth is system dependent, meaning its effective throughput varies with the host platform's memory configuration. The RX 7400 OEM also offers a fixed bus width of 128 bits, while the Arc B370's bus width is system shared. In scenarios where consistent memory performance matters, the discrete AMD solution is preferable.

Architecture Differences

The two GPUs come from fundamentally different design philosophies. The AMD Radeon RX 7400 OEM uses the Navi 33 chip, built on RDNA 3.0 architecture with the codename Hotpink Bonefish. It belongs to the Navi III (RX 7000) generation and is fabricated by TSMC on a 6 nm process node. The die contains 13,300 million transistors across 204 mm², yielding a transistor density of 65.2M per mm². The Intel Arc B370 uses the Panther Lake chip with Xe3-LPG architecture and belongs to the Arc Graphics-M (Panther Lake) generation. It is built on a 3 nm process node at Intel's own foundry, though the transistor count and die size are listed as unknown in the database.

The memory architecture differs completely. The RX 7400 OEM uses 8 GB of GDDR6 on a 128-bit bus, delivering 172.8 GB/s. The Arc B370 uses system shared memory with a system dependent bus width and bandwidth, meaning it draws from the host's main memory rather than dedicated VRAM. This makes the AMD card a standalone discrete solution, while the Intel part functions as an integrated GPU. The RX 7400 OEM requires a single 6-pin power connector and a suggested 250 W power supply, fitting into a single-slot form factor at 167 mm length. The Arc B370 needs no power connectors and is classified as an IGP, with dimensions not recorded.

In compute resources, the RX 7400 OEM has 1792 shading units, 112 TMUs, 64 ROPs, and 28 RT cores. The Arc B370 has 1280 shading units, 40 TMUs, 20 ROPs, and 10 RT cores. The AMD part has 40% more shading units, 2.8 times the TMUs, 3.2 times the ROPs, and 2.8 times the RT cores. Clock speeds differ notably: the RX 7400 OEM runs at a 330 MHz base and 1100 MHz boost, while the Arc B370 runs at a 300 MHz base and 2400 MHz boost. The Intel part's higher boost clock compensates somewhat for its lower resource count, but the AMD part's higher pixel and texture rates show that the extra hardware wins out in fill-rate-bound tasks.

Both GPUs support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The RX 7400 OEM provides display outputs of 1x HDMI 2.1a and 3x DisplayPort 2.1, while the Arc B370's outputs are portable device dependent. The memory clock on the RX 7400 OEM is 1350 MHz, translating to 10.8 Gbps effective, while the Arc B370 has no fixed memory clock due to its shared memory design. The RX 7400 OEM's release date is recorded as 2025-08-07, with a predecessor of Navi II and successor of Navi IV. The Arc B370's release date is 2026-01-26, and it has no recorded predecessor or successor, with an active production status.

The Verdict

The benchmark data indicates that the AMD Radeon RX 7400 OEM is the stronger performer for discrete graphics workloads. Its FP32 output of 7.885 TFLOPS, texture rate of 123.2 GTexel/s, and pixel rate of 70.40 GPixel/s all exceed the Intel Arc B370's corresponding figures of 6.144 TFLOPS, 96.00 GTexel/s, and 48.00 GPixel/s. The RX 7400 OEM also provides dedicated 8 GB GDDR6 memory with 172.8 GB/s bandwidth, a fixed 128-bit bus, and a PCIe 4.0 x8 interface, making it suitable for desktop systems where consistent memory performance is required. Its 50th percentile ranking among all GPUs places it in the middle of the performance distribution, while the Arc B370's 5th percentile ranking places it near the bottom.

The Intel Arc B370 is the choice for power-constrained or integrated scenarios. Its 25 W TDP is 30 W lower than the RX 7400 OEM's 55 W TDP, and its IGP classification with no power connectors makes it appropriate for portable devices where a discrete card cannot be installed. The FP16 throughput of 12.29 TFLOPS, achieved via a 2:1 ratio, is the only compute metric where the Intel part leads, and it will matter for applications that can use half-precision arithmetic. The Arc B370's 3DMark Steel Nomad DX12 score of 1184, while modest, keeps it within 1% of several older ATI/AMD parts, indicating that its performance is comparable to legacy mid-range hardware from over a decade ago.

For users building a desktop with room for a single-slot, 167 mm card, the RX 7400 OEM offers more shading units, more ROPs, more RT cores, and dedicated memory. The data does not record any benchmark scores for the RX 7400 OEM, but its specification sheet points to clear wins in rasterization and pixel-bound tasks. The Arc B370, with its 2400 MHz boost clock and 3 nm process, is a low-power integrated solution that fits a different niche entirely. The verdict from the recorded data is straightforward: the RX 7400 OEM for discrete performance, the Arc B370 for integrated efficiency and FP16 workloads.
