AMD Radeon 8040S vs AMD Radeon PRO W7400 Comparison

The AMD Radeon 8040S and AMD Radeon PRO W7400 are two very different GPUs aimed at different segments of the market, despite sharing the same manufacturer and a 55 W TDP. The 8040S is an integrated graphics processor (IGP) built into the Strix Halo chip for mobile devices, using RDNA 3.5 architecture on a 4 nm process. The PRO W7400 is a discrete, single-slot professional workstation card based on the Navi 33 chip, using RDNA 3.0 on a 6 nm process. The database shows no head-to-head benchmark results between these two, and the PRO W7400 has no recorded benchmark scores in our database. The 8040S has a complete set of PassMark scores, an average benchmark score of 2440, and sits at the 17th percentile of all GPUs. The PRO W7400, by contrast, has an average benchmark score of 0 in the database and rests at the 50th percentile. This means that any performance comparison must rely on the architectural and specification differences recorded in the data, rather than direct measurements.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries for the Radeon 8040S and the Radeon PRO W7400. The head-to-head table is empty, with zero wins recorded for either part. This absence of direct comparison data is itself informative: it indicates that these products are not typically evaluated against each other in the same test suite. The 8040S, as an IGP, is benchmarked within the context of integrated graphics and low-power mobile solutions. The PRO W7400, as a professional discrete card, is expected to be tested in workstation scenarios, but no such scores are present in the database.

For the Radeon 8040S, the recorded PassMark scores are as follows: DirectX 10 scores 48, DirectX 11 scores 80, DirectX 12 scores 47, DirectX 9 scores 134, G2D scores 1052, G3D scores 10578, and GPU Compute scores 5138. These numbers show a pattern typical of a low-power integrated solution. The G3D score of 10578 is the standout figure, indicating that the 8040S can handle some 3D workloads, but the very low DirectX scores (all below 135) suggest that API-specific tests reveal significant limitations. The compute score of 5138 is comparatively strong relative to the DirectX scores, which may reflect the architecture's compute-oriented design.

The nearest rivals in the database for the 8040S provide context for its average score of 2440. The NVIDIA GeForce 710M has an average score of 2433, which is 0.3% lower. The Intel HD Graphics 610 averages 2425, 0.6% lower. The NVIDIA GeForce GT 710M averages 2422, 0.7% lower. The AMD Radeon RX 7400 averages 2467, which is 1.1% higher than the 8040S. This cluster of scores, all within a narrow band around 2422 to 2467, shows that the 8040S performs in the same class as these older, low-end discrete and integrated parts. The 8040S is effectively at parity with its nearest rivals, with deltas under 1.1% in either direction.

The PRO W7400 has no benchmark scores in the database. Its average benchmark score is listed as 0, and there are no nearest rivals recorded. This absence of data means that no quantitative performance claims can be made about the PRO W7400 from our measurements. The only performance-related figures available are its theoretical specifications, such as pixel rate, texture rate, and floating-point throughput, which are derived from its clock speeds and core counts. These are not benchmark results but rather calculated capabilities.

The data shows that the 8040S, despite having a lower theoretical peak performance than the PRO W7400 in several metrics, at least has measurable benchmark results. The PRO W7400's theoretical specifications suggest it should be faster, but without recorded benchmarks, the database cannot confirm this. The 8040S's percentile rank of 17 places it in the lower quartile of all GPUs, while the PRO W7400's percentile rank of 50 places it exactly at the median, but this percentile for the PRO W7400 is not supported by any actual score data.

The Verdict

Based strictly on the recorded data, the Radeon 8040S is the only one of the two with any benchmark results. Its average score of 2440 and its position among rivals like the GeForce 710M and HD Graphics 610 indicate that it delivers performance consistent with entry-level integrated graphics. The PRO W7400, with no benchmark scores, cannot be assessed for real-world performance from the database. Its specifications, however, point to a much more capable part.

The PRO W7400 has 1792 shading units compared to 1024 for the 8040S. It has 112 texture mapping units versus 64, and 64 render output units versus 32. It has 28 ray tracing cores versus 16. Its FP32 compute is rated at 7.885 TFLOPS, which is higher than the 8040S's 5.734 TFLOPS. Its texture rate is 123.2 GTexel/s versus 179.2 GTexel/s for the 8040S, which is a notable reversal. The 8040S has a higher texture rate despite having fewer TMUs, because its boost clock is 2800 MHz, much higher than the PRO W7400's 1100 MHz boost. The 8040S also has a higher pixel rate at 89.60 GPixel/s versus 70.40 GPixel/s for the PRO W7400.

The memory situation is entirely different. The 8040S uses System Shared memory, meaning its bandwidth is system dependent and cannot be quantified in the database. The PRO W7400 has 8 GB of GDDR6 memory on a 128-bit bus, delivering 172.8 GB/s of bandwidth. For any workload that relies heavily on memory bandwidth, the PRO W7400 has a clear advantage, as it has dedicated, fast memory rather than sharing system memory. For the 8040S, memory performance depends entirely on the host system's memory configuration, which is not specified in the data.

The verdict from the data is that the PRO W7400 is the more powerful GPU on paper, with higher core counts, more ray tracing cores, higher FP32 throughput, and dedicated memory. The 8040S, however, is the only one with proven benchmark results, and those results place it in the same performance class as decade-old entry-level mobile GPUs. The PRO W7400's lack of benchmark data makes it impossible to confirm its real-world performance, but its specifications suggest it should outperform the 8040S in most compute and graphics tasks.

Where Each One Wins

The 8040S wins in the category of measured performance, since it has actual benchmark scores while the PRO W7400 has none. Its texture rate of 179.2 GTexel/s is higher than the PRO W7400's 123.2 GTexel/s, and its pixel rate of 89.60 GPixel/s exceeds the PRO W7400's 70.40 GPixel/s. These higher rates are due to the 8040S's much higher boost clock of 2800 MHz compared to 1100 MHz. In scenarios where texture fill and pixel fill are the dominant factors, and where memory bandwidth is not a bottleneck, the 8040S could potentially deliver higher throughput. Its integrated nature also means it has no power connector requirement and no additional slot width, as it is an IGP, which is an advantage for ultra-portable designs.

The PRO W7400 wins in raw compute capability. Its FP32 of 7.885 TFLOPS is higher than the 8040S's 5.734 TFLOPS. It has more shading units (1792 vs 1024), more TMUs (112 vs 64), more ROPs (64 vs 32), and more ray tracing cores (28 vs 16). Its memory subsystem is fully specified: 8 GB of GDDR6 on a 128-bit bus with 172.8 GB/s bandwidth, which is a fixed and known quantity, unlike the 8040S's system-dependent memory. The PRO W7400 also has four DisplayPort 2.1 outputs, while the 8040S's display outputs are portable device dependent. For professional workloads that require dedicated memory, higher compute throughput, and multiple display outputs, the PRO W7400 is designed to win.

The process node difference also matters. The 8040S uses a 4 nm process from TSMC, while the PRO W7400 uses a 6 nm process. The 8040S has a larger die size at 308 mm² compared to the PRO W7400's 204 mm². The PRO W7400 has a known transistor count of 13,300 million, while the 8040S's transistor count is unknown. The PRO W7400's transistor density is recorded as 65.2M per mm², while the 8040S's density is not listed. These differences suggest that the 8040S is a larger, more complex chip, but the PRO W7400 has a higher density of transistors per area.

In terms of use cases, the data suggests the 8040S is suited for mobile devices where power consumption is capped at 55 W and space is at a premium, given its IGP slot width. The PRO W7400, also at 55 W TDP, is a discrete single-slot card that requires a 250 W suggested PSU and uses PCIe 4.0 x8, making it suitable for workstation builds where dedicated memory and multiple DisplayPort outputs are needed.
