AMD Radeon R5 M335 vs AMD Radeon R7 Graphics Comparison

The Verdict

The data splits cleanly by workload. The AMD Radeon R7 Graphics wins the Vulkan benchmark by a decisive 25.7% margin, scoring 5980 against the R5 M335’s 4758. The AMD Radeon R5 M335 wins the OpenCL benchmark by 15.4%, posting 4745 versus the R7 Graphics’ 4015. The average benchmark score favors the R7 Graphics at 4998, which is 5.2% ahead of the R5 M335’s 4752. The R7 Graphics sits in the 29th percentile of all GPUs, while the R5 M335 sits in the 28th — a negligible ranking gap. The verdict is not about a blanket winner but about matching silicon to the API in use. Choose the R7 Graphics for Vulkan-based workloads and the R5 M335 for OpenCL-based workloads. For mixed usage, the R7 Graphics’ higher average score and superior Vulkan showing make it the safer default, provided the system can share memory as it does. The R5 M335’s dedicated 2 GB DDR3 frame buffer gives it a structural edge in OpenCL, but that advantage does not carry into Vulkan.

Where Each One Wins

The R5 M335 wins the OpenCL test outright, scoring 4745 versus the R7 Graphics’ 4015. That is a 730-point gap, or 15.4% in favor of the discrete part. The R7 Graphics wins the Vulkan test by an even larger absolute margin: 5980 versus 4758, a difference of 1222 points, or 25.7%. The win distribution is one benchmark each, but the magnitudes differ. The R7 Graphics’ Vulkan victory is nearly twice as large in percentage terms as the R5 M335’s OpenCL victory. The R7 Graphics also holds the higher average benchmark score at 4998, which places it 0.4% above the NVIDIA Quadro 4000’s 4979 and 0.6% above the GeForce RTX 5060 Ti 16 GB’s 4970. The R5 M335’s average of 4752 puts it 0.5% below the Radeon R8 M445DX’s 4727 and 0.7% below the Radeon R5 M255’s 4788. The data indicates the R7 Graphics is the stronger all-rounder, while the R5 M335 is the specialist for OpenCL compute tasks.

Head-to-Head Benchmarks

The two benchmark results tell opposite stories. In Geekbench OpenCL, the R5 M335 scores 4745 against the R7 Graphics’ 4015. That is a 730-point win for the discrete GPU, translating to a 15.4% delta. The R5 M335’s dedicated memory and higher FP32 throughput (659.2 GFLOPS versus 553.0 GFLOPS) likely drive this result. The texture rate also favors the R5 M335 at 20.60 GTexel/s versus 17.28 GTexel/s, and the pixel rate is 8.240 GPixel/s versus 5.760 GPixel/s. Every raw throughput metric in the specification table points the same way, and the OpenCL benchmark confirms it.

In Geekbench Vulkan, the result flips dramatically. The R7 Graphics scores 5980, while the R5 M335 scores 4758. That is a 1222-point win for the IGP, a 25.7% delta. The R7 Graphics’ newer GCN 2.0 architecture and higher shading unit count (384 versus 320) appear to give it a substantial advantage under the Vulkan API. The R7 Graphics also supports DirectX 12 (12_0), a higher feature level than the R5 M335’s DirectX 12 (11_1), which may contribute to better modern-API performance. The R5 M335’s OpenCL win is solid but narrow in percentage terms; the R7 Graphics’ Vulkan win is both larger in absolute points and in percentage.

The average benchmark scores reflect this split. The R7 Graphics averages 4998, which is 5.2% higher than the R5 M335’s 4752. The R7 Graphics’ nearest rival, the NVIDIA Quadro 4000, sits at 4979, a 0.4% delta. The R5 M335’s nearest rival, the AMD Radeon R8 M445DX, sits at 4727, a 0.5% delta. The percentile ranking is nearly identical — 29th for the R7 Graphics and 28th for the R5 M335 — indicating both are entry-level performers in the broader GPU landscape. The head-to-head record is one win each, but the R7 Graphics holds the edge in average score and in the newer API.
