AMD FirePro W4190M vs AMD Radeon R7 M340 Comparison

Where Each One Wins

The benchmark data splits cleanly between these two mobile GPUs, though the sample size is limited. The AMD Radeon R7 M340 records wins in the only head-to-head benchmark available, while the AMD FirePro W4190M has no recorded victories in the comparison set.

Looking at the broader benchmark landscape, the R7 M340 posts an average benchmark score of 5063 across two recorded tests. That places it at the 30th percentile of all GPUs in the database. Its Geekbench OpenCL score reaches 4932, and its Geekbench Vulkan score climbs to 5193. The Vulkan result is notably higher than the OpenCL figure, suggesting the GCN 3.0 architecture translates well to that API layer.

The FirePro W4190M, by contrast, has only one recorded benchmark result. Its Geekbench OpenCL score is 4505, and its average benchmark score sits at 4505 as well. The 26th percentile ranking places it slightly below the R7 M340 in the overall distribution. Without a Vulkan result recorded for the FirePro, the data cannot confirm whether its GCN 1.0 architecture would show a similar API scaling pattern.

The wins distribution is straightforward: the R7 M340 takes 1 head-to-head win, and the FirePro W4190M takes 0. The single comparison, Geekbench OpenCL, favors the R7 M340 by 9.5%. That is a meaningful margin in synthetic compute workloads, but it represents only one test. The database does not include gaming benchmarks, sustained load tests, or power efficiency measurements for either part.

For compute-oriented tasks that stress OpenCL, the data favors the R7 M340. For workloads that might leverage Vulkan, the R7 M340 again appears stronger based on its recorded 5193 score, though no direct FirePro Vulkan result exists for comparison. The FirePro W4190M does not win any recorded category, so its strengths in this dataset are limited to attributes outside the benchmark suite, such as its form factor and memory configuration.

The Verdict

The recorded data points to a clear but narrow conclusion. The AMD Radeon R7 M340 outperforms the AMD FirePro W4190M in the only head-to-head benchmark available, Geekbench OpenCL, by 9.5%. Its average benchmark score of 5063 is 12.4% higher than the FirePro's 4505. The percentile rankings reinforce this: 30th versus 26th.

Who should pick the R7 M340? Anyone whose workload depends on OpenCL compute performance. The 9.5% lead in the direct comparison, combined with the Vulkan score of 5193, makes it the stronger choice for general-purpose GPU compute in the database's measurements. Its GCN 3.0 architecture and higher clock speeds contribute to this result.

Who should pick the FirePro W4190M? The data does not provide a benchmark-based reason. It loses the only head-to-head test. However, the specification sheet shows a different memory subsystem: GDDR5 on a 128-bit bus delivering 64.00 GB/s, versus DDR3 on a 64-bit bus delivering 16.00 GB/s. That 4x bandwidth advantage could matter in bandwidth-sensitive workloads that the recorded benchmarks do not capture. The FirePro also comes as an MXM Module, a mobile workstation form factor, whereas the R7 M340 has no recorded slot width. For systems requiring that specific module standard, the FirePro is the applicable part.

The verdict from the data alone: the R7 M340 wins on compute benchmarks. The FirePro W4190M remains relevant only for its bandwidth and form-factor characteristics, which the benchmark suite does not measure.

Head-to-Head Benchmarks

The database records one head-to-head comparison between these two GPUs. The test is Geekbench OpenCL, and the result is decisive.

The AMD Radeon R7 M340 scores 4932. The AMD FirePro W4190M scores 4505. The delta is 9.5% in favor of the R7 M340. That margin is substantial for a single compute test. It places the R7 M340 ahead of the FirePro by roughly the same gap that separates the FirePro from its nearest rivals in the database.

Context from the nearest rivals helps interpret these numbers. The R7 M340's average score of 5063 ties exactly with the AMD Radeon R7 240, which also posts 5063 with a 0% delta. It sits 0.6% above the AMD FirePro W4170M at 5034, 0.9% above the AMD Radeon R5 M430 at 5018, and 1.3% above the AMD Radeon R7 Graphics at 4998. This cluster of scores, all within 1.3% of each other, suggests the R7 M340 is positioned in a tight competitive band of low-end mobile and desktop GPUs.

The FirePro W4190M's nearest rivals tell a different story. Its average score of 4505 is 0.1% above the AMD Radeon R7 M260 at 4499. The Intel HD Graphics P530 scores 4560, which is 1.2% higher than the FirePro. The AMD Radeon RX 560 scores 4569, 1.4% higher. The AMD Radeon R5 M230 scores 4577, 1.6% higher. Notably, the FirePro is the second-lowest scoring part in its own rival cluster, ahead of the R7 M260 but behind three other GPUs.

The head-to-head result fits this pattern. The R7 M340's 4932 OpenCL score is closer to its own average of 5063 than the FirePro's 4505 is to its average of 4505. In fact, the R7 M340's OpenCL score is 9.5% higher than the FirePro's, which is a larger gap than any delta within either GPU's nearest-rival cluster. This indicates that while both GPUs sit in the low end of the performance distribution, the R7 M340 holds a clearer advantage over the FirePro than either GPU shows over its closest competitors.

Architecture Differences

The two GPUs use different underlying chips. The R7 M340 is built on the Meso chip with the GCN 3.0 architecture. The FirePro W4190M uses the Opal chip with GCN 1.0 architecture. Both are fabricated by TSMC on 28 nm, but the transistor counts differ significantly: the Meso packs 1,550 million transistors on a 125 mm² die, while Opal uses 950 million transistors on 77 mm². The resulting transistor density is nearly identical in the database at 12.4 million per square millimeter for Meso and 12.3 million per square millimeter for Opal.

The R7 M340 belongs to the Gem System generation, labeled under the R7 M300 generation umbrella, with predecessor Solar System and successor Polaris Mobile. The FirePro W4190M belongs to FirePro Mobile generation, under the Wx100M generation grouping, with predecessor FirePro Mobility and successor Radeon Pro Mobile. Both are marked as end-of-life in production status.

The shading unit counts favor the FirePro W4190M with 384 shading units versus the R7 M340's 320. The texture mapping units also favor the FirePro with 24 million texture units against 20 million. Both share the same 8 ROPs, and neither has recorded ray tracing cores or tensor cores in the database. The R7 M340's GCN 1.0 architecture supports 1:1 FP16 with a recorded 653.4 GFLOPS for FP16, while the FirePro W4190M does not record an FP16 score in the database.

The API support differs in one key area. The R7 M340 lists DirectX 12 (12_0) while the FirePro W4190M lists DirectX 12 (11_1). OpenGL 4.6 and Vulkan 1.2.170 appear in both parts.

Specification Differences

The specification sheet highlights several areas where these two mobile GPUs diverge from each other.

The clock speeds are different across the core. The R7 M340 base clocks at 943 MHz with boost to 1021 MHz. The FirePro W4190M base clocks at 825 MHz with boost to 900 MHz. Memory clocks are the same in the database at 1000 MHz, but the effective data rate differs: the R7 M340 runs 2 Gbps effective, while the FirePro W4190M runs 4 Gbps effective.

The memory subsystem shows the biggest differences. The R7 M340 uses 2 GB DDR3 on a 64-bit bus with bandwidth 16.00 GB/s. The FirePro W4190M uses 2 GB GDDR5 on a 128-bit bus with bandwidth 64.00 GB/s. The FirePro's bandwidth is four times higher, which is the most striking specification gap between the two parts.

The FirePro W4190M records a slot width of MXM Module, while the R7 M340 has no slot width recorded. The FirePro W4190M also lists power connectors as None, and display outputs as Portable Device Dependent, while the R7 M340 has no recorded values for either. Both use PCIe 3.0 x8 bus interface.

Compute rates differ despite the FirePro having more shading units. The R7 M340 achieves 653.4 GFLOPS FP32, while the FirePro W4190M reaches 691.2 GFLOPS FP32. The FirePro's higher shading unit count gives it a 5.8% raw FP32 advantage, but its lower clocks and the R7 M340's newer architecture offset this in the OpenCL benchmark. The pixel rate also favors the R7 M340 at 8.168 GPixel/s versus 7.200 GPixel/s for the FirePro W4190M. The texture rate is closer, with the R7 M340 at 20.42 GTexel/s and the FirePro W4190M at 21.60 GTexel/s.

The FirePro M340 was released on 2015-05-04, while the FirePro W4190M was released six months later on 2015-11-11. Neither part records a launch MSRP in the database.
