AMD Radeon R7 M340 vs NVIDIA GeForce 930M Comparison

Head-to-Head Benchmarks

The recorded data presents a split decision between these two mobile graphics processors. In the Geekbench OpenCL test, the NVIDIA GeForce 930M edges ahead with a score of 5046 against the AMD Radeon R7 M340's 4932, a margin of 2.3 percent. That is a narrow victory, close enough that the two solutions are effectively peer-level in raw compute workloads under this particular API. The AMD part does not trail by a meaningful amount, and the delta sits well within run-to-run variance territory for most benchmark scenarios.

The Geekbench Vulkan test tells a completely different story. Here the AMD Radeon R7 M340 posts 5193, while the NVIDIA GeForce 930M manages only 3729. That translates to a 39.3 percent advantage for AMD, a substantial gap that reshapes the overall comparison. One win apiece does not capture the magnitude of these swings. The OpenCL result is a near tie, but the Vulkan result is a rout. When a database user looks at the average benchmark score, the AMD part lands at 5063, which is 15.4 percent higher than the NVIDIA part's 4388 average. The percentile placement reflects this: the R7 M340 sits at the 30th percentile of all GPUs, while the 930M sits at the 26th percentile.

Digging into the rival comparisons from the database, the AMD R7 M340's average score of 5063 exactly matches the AMD Radeon R7 240 at 5063, with a delta of 0 percent. The FirePro W4170M trails at 5034, 0.4 percent behind, while the R5 M430 at 5034 is 0.9 percent behind the R7 M340. The integrated Radeon R7 Graphics at 4998 sits 1.3 percent lower. For the NVIDIA side, the GeForce GT 645M at 4411 is 0.5 percent behind the 930M, the Intel Iris Pro 5200 at 4360 is 0.7 percent ahead, and the RTX 4070 GDDR6 at 4335 is 1.2 percent ahead. The RTX 4070 appearing in this list is unusual in the database, but the delta is small. The FirePro W2100 at 4295 is 2.2 percent ahead of the 930M.

Where Each One Wins

The AMD Radeon Vulkan result is the clear differentiator. A 39.3 percent lead in Vulkan compute over the NVIDIA part signals that the GCN 3.0 architecture scales better under this modern API in this generation. The R7 M340's FP32 throughput of 653.4 GFLOPS is substantially higher than the 421.4 GFLOPS of the 930M, and that compute-heavy workloads that leverage raw shader math favor the AMD silicon. The texture rate of 20.42 GTexel/s versus the 13.18 GTexel/s further cements AMD's position in fill-rate-bound tasks. The pixel rates, though, flip: the R7 M340 manages 8.17 GPixel/s against the 4.39 GPixel/s of the 930M, a 86 percent advantage for AMD in pixel throughput metrics.

The NVIDIA GeForce 930M wins where drivers and API maturity matter less. OpenCL performance at 5046 versus 4932 is a win, but a slim one. The Maxwell architecture with 384 shading units, 24 TMUs, and 8 ROPs, runs at 549 MHz base and boost locked at 549 MHz, a low clock that limits its raw compute. Yet its shading unit count is higher than the AMD 320, 20 TMUs, and 8 ROPs, clocked at 943 MHz base and 1021 MHz boost. The NVIDIA memory clock at 800 MHz effective 1,600 Mbps effective, with a bandwidth of 12.80 GB/s, trails the AMD memory at 2,000 MHz effective 2 Gbps effective, at 16.00 GB/s. The NVIDIA TDP is rated at 33 W, with no power connectors, while the AMD TDP field is not recorded in the database.

The data shows the AMD R7 M340's average score of 5063 versus the 4388 of the 930M means the AMD part wins the aggregate benchmark race. Users running a broad suite of tests see the AMD part floating near the 30th percentile, while the NVIDIA part hovers near the 26th percentile. Specific API differences matter more than the raw average score.

The Verdict

From the database's measurements, the AMD Radeon Vulkan result of 5193 versus 3729 for NVIDIA means the AMD part has a 39.3 percent advantage in Vulkan compute. The AMD R7 M340's average score of 5063 beats the NVIDIA GeForce 930M's 4388 by 15.4 percent. The OpenCL score of 5046 for NVIDIA against 4932 for AMD shows a 2.3 percent lead for NVIDIA, but that is within noise, the delta is small. This data suggests users prioritizing Vulkan-based applications should pick AMD. The AMD R7 M340's average score of 4932 in Vulkan, while the NVIDIA GeForce 930M's 5046 in OpenCL, the OpenCL is a narrow win for NVIDIA, but the Vulkan is a decisive win for AMD.
