AMD Radeon RX 7400 OEM vs Intel Arc Graphics 64EU Comparison

Head-to-Head Benchmarks

The recorded data shows no direct head-to-head benchmark comparisons between the AMD Radeon RX 7400 OEM and the Intel Arc Graphics 64EU. The database contains a single benchmark entry for the Intel part, while the AMD Radeon RX 7400 OEM has no recorded benchmark scores. This asymmetry limits direct numerical comparison, but the available data points and architectural specifications provide a clear performance hierarchy.

The Intel Arc Graphics 64EU scores 733 in 3dmark Steel Nomad DX12. This places the integrated graphics solution at the 3rd percentile among all GPUs in the database. The nearest rivals for the Intel part include the Intel Arc Graphics 32EU and the Intel Arc Graphics 24EU, both scoring 733 with a 0% delta. The AMD Radeon HD 6470M trails at 723, which is 1.4% behind, while the NVIDIA GeForce GT 415M leads at 751, putting the Intel Arc Graphics 64EU 2.4% behind that mobile part.

The AMD Radeon RX 7400 OEM has no benchmark entries and no nearest rivals listed. However, its raw compute specifications dwarf those of the Intel integrated solution. The AMD part delivers 7.885 TFLOPS of FP32 performance, while the Intel Arc Graphics 64EU delivers 1.946 TFLOPS. This represents a 4.05x advantage in raw shader throughput for the discrete AMD card. The pixel rate comparison shows 70.40 GPixel/s for AMD versus 30.40 GPixel/s for Intel, a 2.32x margin. The texture rate favors AMD at 123.2 GTexel/s versus 60.80 GTexel/s, a 2.03x advantage.

Memory bandwidth further separates the two. The AMD Radeon RX 7400 OEM uses 8 GB of GDDR6 memory on a 128-bit bus, delivering 172.8 GB/s of bandwidth. The Intel Arc Graphics 64EU relies on system shared memory with bandwidth described as system dependent. This means the Intel part's memory performance varies with the host platform, while the AMD card has dedicated, consistent bandwidth.

Architecture Differences

The two GPUs come from different architectural families and manufacturing processes. The AMD Radeon RX 7400 OEM uses the Navi 33 chip built on RDNA 3.0 architecture, codenamed Hotpink Bonefish. It belongs to the Navi III generation within the RX 7000 series. The chip is fabricated on a 6 nm process at TSMC, containing 13,300 million transistors on a 204 mm² die, yielding a transistor density of 65.2M per mm².

The Intel Arc Graphics 64EU uses the Arrow Lake-S chip built on Xe-LPG architecture, part of the Arc Graphics generation for Arrow Lake. Intel fabricates this chip on a 3 nm process at TSMC, with 17,800 million transistors on a 243 mm² die. The transistor density reaches 73.3M per mm². The Intel die is larger and denser, but this includes substantial non-GPU components since it is an integrated processor graphics solution.

The compute unit configurations differ substantially. The AMD Radeon RX 7400 OEM has 1792 shading units, 112 texture mapping units, 64 render output units, and 28 ray tracing cores. The Intel Arc Graphics 64EU has 512 shading units, 32 texture mapping units, and 16 render output units. Intel does not list dedicated ray tracing cores for this part. The AMD card supports FP16 at a 1:1 ratio with FP32, while the Intel part runs FP16 at a 2:1 ratio, meaning it processes twice as many FP16 operations per clock as FP32 operations.

Clock speeds show a different design philosophy. The AMD Radeon RX 7400 OEM runs a base clock of 330 MHz with a boost clock of 1100 MHz. The Intel Arc Graphics 64EU runs a base clock of 300 MHz but boosts to 1900 MHz. The higher boost clock partially compensates for the Intel part's smaller compute array, but the sheer difference in shading units remains decisive.

Memory architecture is another key differentiator. The AMD card uses dedicated GDDR6 memory with a 128-bit interface and fixed bandwidth of 172.8 GB/s. The Intel integrated solution uses system shared memory with system dependent bandwidth, meaning performance scales with the host CPU's memory configuration. The AMD card also has dedicated display outputs including 1x HDMI 2.1a and 3x DisplayPort 2.1, while the Intel part's display outputs are motherboard dependent.

Power characteristics separate discrete from integrated designs. The AMD Radeon RX 7400 OEM has a 55 W TDP, uses a single 6-pin power connector, requires a 250 W suggested PSU, and occupies a single slot with a 167 mm length. The Intel Arc Graphics 64EU has a 65 W TDP, draws power from the motherboard with no dedicated connectors, and has no physical dimensions since it is an IGP. The AMD part uses a PCIe 4.0 x8 bus interface, while the Intel part connects via ring bus.

Where Each One Wins

The AMD Radeon RX 7400 OEM wins decisively in raw compute throughput. The 7.885 TFLOPS FP32 figure is 4.05x higher than the Intel part's 1.946 TFLOPS. This translates to substantial advantages in pixel fill rate, texture fill rate, and memory bandwidth. The 172.8 GB/s dedicated bandwidth versus system dependent bandwidth means the AMD card maintains consistent performance regardless of host platform memory configuration.

The AMD card also wins in memory capacity with 8 GB of dedicated GDDR6 versus system shared memory for Intel. The 128-bit memory bus provides a fixed, predictable bandwidth figure. The discrete card's 64 ROPs versus 16 ROPs for Intel gives it a 4x advantage in pixel processing, which matters for high-resolution rendering and multi-sample anti-aliasing workloads.

The Intel Arc Graphics 64EU wins in power efficiency relative to its physical footprint. As an integrated solution, it requires no additional slot space and no power connectors. The 65 W TDP is only 10 W higher than the AMD card's 55 W, but the Intel part is built into the processor, eliminating the need for a separate card. The higher boost clock of 1900 MHz versus 1100 MHz suggests better clock scaling under boost conditions.

The Intel part also wins in the FP16 compute ratio, processing FP16 at 2:1 versus the AMD card's 1:1 ratio. This gives the Intel part 3.891 TFLOPS of FP16 performance, which is 2x its FP32 figure. The AMD card matches FP16 to FP32 at 7.885 TFLOPS. For workloads that leverage FP16 precision, the Intel part's relative advantage in that format is notable, though the AMD card still has higher absolute FP16 throughput.

The Verdict

The data indicates a clear performance gap between these two products. The AMD Radeon RX 7400 OEM is a discrete graphics card with dedicated memory, a 4.05x FP32 compute advantage, and 4x the render output units. The Intel Arc Graphics 64EU is an integrated processor graphics solution with system shared memory and a fraction of the compute resources. The absence of benchmark scores for the AMD card in the database limits direct performance comparison, but the architectural specifications show a dominant position for the discrete card.

The AMD Radeon RX 7400 OEM suits workloads requiring sustained, dedicated graphics performance. The 8 GB of GDDR6 memory with 172.8 GB/s bandwidth supports texture-heavy applications without competing with the CPU for system memory. The 64 ROPs and 28 ray tracing cores provide hardware acceleration for modern rendering pipelines. The 55 W TDP with a single 6-pin connector makes it suitable for compact builds that still need discrete graphics capability.

The Intel Arc Graphics 64EU suits systems where physical space and simplicity take priority. As an IGP, it requires no additional slot, no power connectors, and no separate card dimensions. The 3.891 TFLOPS FP16 performance indicates some capability for mixed-precision workloads, and the 1900 MHz boost clock shows aggressive clock scaling. The 3rd percentile ranking among all GPUs confirms this is an entry-level integrated solution.

The recorded benchmark data shows the Intel part at 733 in Steel Nomad DX12, with nearest rivals all within 2.4% of that score. The AMD card has no recorded benchmark scores and no nearest rivals, which the database indicates through its 50th percentile ranking. This percentile figure reflects the AMD card's position relative to all GPUs, placing it at the median of the database distribution. The Intel part sits at the 3rd percentile, indicating the wide gap between these two products in the performance distribution.

For systems requiring dedicated graphics memory, high pixel throughput, and consistent bandwidth, the AMD Radeon RX 7400 OEM provides the required specifications. For systems where integrated graphics suffices and physical footprint matters, the Intel Arc Graphics 64EU serves that role. The data does not support any scenario where the Intel part outperforms the AMD card in raw graphics workloads, given the 4.05x FP32 advantage, 2.32x pixel rate advantage, and 2.03x texture rate advantage held by the AMD part.
