AMD Radeon RX 7400 OEM vs Intel Arc 140V Mobile Comparison

Head-to-Head Benchmarks

The recorded database contains no direct head-to-head benchmark entries for the AMD Radeon RX 7400 OEM versus the Intel Arc 140V Mobile. Both products sit at the 50th percentile among all GPUs in the database, indicating they occupy a similar mid-tier position in overall performance distribution. However, their architectural characteristics and measured specifications point to divergent strengths that can be analyzed from the available data.

The AMD Radeon RX 7400 OEM delivers 7.885 TFLOPS of FP32 compute performance, which is nearly double the 3.994 TFLOPS of the Intel Arc 140V Mobile. This gives the AMD part a clear advantage in raw shader throughput, with the Arc 140V reaching only about 50.7% of the RX 7400's FP32 output. In FP16 workloads, the situation shifts: the Intel part achieves 7.987 TFLOPS due to its 2:1 FP16 ratio, slightly edging out the AMD part's 7.885 TFLOPS at a 1:1 ratio. This means the Intel Arc 140V Mobile can process FP16 data at a marginally higher rate, making it competitive in workloads that leverage half-precision arithmetic.

Texture processing rates tell a nuanced story. The AMD RX 7400 OEM produces 123.2 GTexel/s, while the Intel Arc 140V Mobile produces 124.8 GTexel/s. The Intel part holds a slight 1.3% advantage here, despite having fewer texture mapping units (64 versus 112). This is explained by the Intel part's much higher boost clock of 1950 MHz compared to 1100 MHz on the AMD part. Pixel fill rates follow a similar pattern but favor AMD: the RX 7400 OEM achieves 70.40 GPixel/s versus 62.40 GPixel/s on the Arc 140V Mobile, a 12.8% gap that stems from the AMD part's 64 ROPs versus 32 ROPs on the Intel design.

Memory bandwidth heavily favors the discrete AMD solution. The RX 7400 OEM uses 8 GB of GDDR6 memory on a 128-bit bus, delivering 172.8 GB/s of bandwidth. The Intel Arc 140V Mobile uses system shared memory, with bandwidth listed as system dependent. This means the AMD card offers dedicated, predictable memory performance, while the Intel integrated part must share system memory bandwidth with the CPU, a factor that can vary based on the host system's memory configuration.

The Verdict

The data indicates that the AMD Radeon RX 7400 OEM is the stronger choice for applications that depend on raw FP32 compute, dedicated memory bandwidth, and higher pixel throughput. Its 7.885 TFLOPS FP32 performance, 172.8 GB/s dedicated bandwidth, and 70.40 GPixel/s pixel rate give it measurable advantages for traditional rasterization workloads and compute-heavy tasks.

The Intel Arc 140V Mobile, by contrast, shows its strengths in FP16 throughput and texture processing, with 7.987 TFLOPS FP16 and 124.8 GTexel/s. Its 37 W TDP and IGP form factor make it suitable for portable devices where power consumption and space are constrained, while the AMD part's 55 W TDP and single-slot discrete design require a PCIe slot and a 6-pin power connector.

Benchmark results indicate that neither part dominates outright. The AMD RX 7400 OEM leads in memory bandwidth, FP32 compute, pixel rate, and has more shading units (1792 versus 1024), TMUs (112 versus 64), ROPs (64 versus 32), and RT cores (28 versus 8). The Intel Arc 140V Mobile counters with higher boost clock (1950 MHz versus 1100 MHz), higher texture rate, and slightly higher FP16 throughput. The choice depends entirely on whether the workload favors AMD's compute and memory advantages or Intel's clock speed and FP16 efficiency.

Architecture Differences

The AMD Radeon RX 7400 OEM uses the Navi 33 chip built on RDNA 3.0 architecture, codenamed Hotpink Bonefish, from the Navi III (RX 7000) generation.

Where Each One Wins

The AMD Radeon RX 7400 OEM wins in scenarios that demand dedicated memory bandwidth and high FP32 throughput. Its 172.8 GB/s of dedicated GDDR6 bandwidth provides predictable performance for texture-heavy workloads and large data sets, without contention from other system components. The 7.885 TFLOPS FP32 output supports compute-intensive applications like physics simulations, rendering, and scientific workloads that rely on single-precision arithmetic. The 70.40 GPixel/s pixel rate and 64 ROPs make it effective for high-resolution rasterization, while 28 RT cores give it a substantial advantage in ray-traced workloads compared to the Intel part's 8 RT cores.

The Intel Arc 140V Mobile wins in FP16-heavy workloads where its 7.987 TFLOPS FP16 throughput exceeds the AMD part. Its 124.8 GTexel/s texture rate edges out the AMD card, and its higher 1950 MHz boost clock suggests better responsiveness in latency-sensitive scenarios. The 37 W TDP and IGP form factor make it suitable for portable devices where power efficiency and space are priorities. The 3 nm process node indicates a more advanced manufacturing technology, potentially enabling better power efficiency per transistor on the Intel side.

For gaming, the AMD part's higher FP32 performance, larger memory bandwidth, and more ROPs position it as the stronger choice for traditional rasterization at higher resolutions. The Intel part's FP16 advantage may benefit newer games that use half-precision shader paths, though its system shared memory could become a bottleneck in memory-intensive scenes.
