AMD Radeon R5 M435 vs NVIDIA GeForce GTX 770M Comparison

The benchmark data places the NVIDIA GeForce GTX 770M clearly ahead of the AMD Radeon R5 M435, with a decisive victory in the only shared test. While both are end-of-life mobile parts, the GTX 770M’s performance profile is substantially stronger, making it the superior choice for demanding tasks, whereas the R5 M435 occupies a more modest segment.

Head-to-Head Benchmarks

The sole direct comparison available is the Geekbench OpenCL test, and the result is not close. The NVIDIA GeForce GTX 770M scores 8552, while the AMD Radeon R5 M435 scores 5859. This represents a 46% advantage for the NVIDIA part. This is a substantial margin that indicates a clear tier difference between the two GPUs, not just a minor clock-speed or memory-bandwidth edge.

Looking at the broader context, the GTX 770M’s average benchmark score is 6000, which places it in the 35th percentile of all GPUs. The R5 M435’s average score is 5859, putting it in the 33rd percentile. While the percentile difference is small (2 points), the absolute performance gap in the OpenCL workload is significant. The GTX 770M’s score of 8552 is over 42% higher than its own average, suggesting that the OpenCL test is particularly favorable to its architecture, while the R5 M435’s OpenCL score of 5859 is exactly its average, indicating this is a representative workload for that chip.

The nearest rivals for each GPU further highlight the separation. The GTX 770M’s closest competitor is the AMD Radeon RX 6400, with an average score of 6001, a 0% delta. It also sits near the NVIDIA RTX PRO 6000 Blackwell Server (5996, 0.1% delta) and the AMD FirePro W4100 (5987, 0.2% delta). This cluster shows the GTX 770M is competing in a performance bracket where scores hover around 6000. In contrast, the R5 M435’s nearest rivals are the AMD Radeon R7 M465 (5841, 0.3% delta), Intel UHD Graphics 730 (5929, -1.2% delta), AMD Radeon HD 8730M (5955, -1.6% delta), and NVIDIA Quadro K620M (5957, -1.6% delta). The R5 M435’s rivals are all slightly weaker, with negative deltaPct values indicating the R5 M435 is actually ahead of them, but the overall score range is lower than the GTX 770M’s rival group. The data shows the GTX 770M is positioned in a higher performance class, evidenced by the 46% delta in the head-to-head test.

The Verdict

The data is unambiguous: the NVIDIA GeForce GTX 770M is the faster GPU. Any user prioritizing raw compute performance should select it without hesitation. The 46% lead in the Geekbench OpenCL test is a comprehensive victory, reflecting advantages in shading units, texture units, memory bandwidth, and raw FP32 throughput.

Specifically, the GTX 770M’s FP32 performance of 1.530 TFLOPS is more than double the R5 M435’s 659.2 GFLOPS. Its pixel rate of 15.94 GPixel/s and texture rate of 63.76 GTexel/s dwarf the R5 M435’s 8.240 GPixel/s and 20.60 GTexel/s respectively. The GTX 770M also has a significantly larger memory bus (192-bit vs 64-bit) and higher bandwidth (96.19 GB/s vs 36.00 GB/s), which is critical for high-resolution textures and data-intensive workloads.

For a user with a laptop that supports an MXM module, the GTX 770M is the obvious choice. It offers a far more capable compute platform. However, the R5 M435 is an integrated graphics processor (IGP) with a PCIe 3.0 x8 interface, making it suitable for lightweight, power-efficient systems where discrete graphics are not an option. The choice is not about value; it is about capability and system design. If the system can house the GTX 770M, the benchmark results recommend it. If the system is limited to an IGP, the R5 M435 is what the data supports, but it will deliver less than half the OpenCL performance of the GTX 770M.

The GTX 770M’s FP32 performance is 1.530 TFLOPS, versus 659.2 GFLOPS for the R5 M435. The GTX 770M has a TDP of 75 W and uses an MXM Module slot, while the R5 M435 has no listed TDP and is an IGP with a PCIe 3.0 x8 interface.

Architecture Differences

The architectural divide is clear. The NVIDIA GeForce GTX 770M is based on the Kepler architecture, manufactured on a 28 nm process at TSMC. The AMD Radeon R5 M435 uses the GCN 1.0 architecture, also on a 28 nm process at TSMC. The transistor density is similar, with the GTX 770M at 11.5M / mm² and the R5 M435 at 12.3M / mm², but the total transistor count is vastly different due to die size. The GTX 770M belongs to the GeForce 700M generation, with a release date of 2013-05-29, while the R5 M435 is from the Gem System (R5 M400) generation, released on 2016-05-14. The GTX 770M’s predecessor is the GeForce 600M and its successor is the GeForce 800M. The R5 M435’s predecessor is the Solar System series and its successor is Polaris Mobile.

The GTX 770M supports DirectX 12 (11_0), OpenGL 4.6, and Vulkan 1.2.175. The R5 M435 supports DirectX 12 (11_1), OpenGL 4.6, and Vulkan 1.2.170. The GTX 770M has a higher DirectX feature level and a slightly newer Vulkan version. Neither GPU has ray tracing cores or tensor cores. The GTX 770M is a discrete MXM module, while the R5 M435 is an integrated processor (IGP), which fundamentally affects their deployment in portable devices. Both have display outputs that are "Portable Device Dependent."

Where Each One Wins

The NVIDIA GeForce GTX 770M wins decisively in every compute and graphics throughput metric from the data. It offers more than double the FP32 performance, a 93% higher pixel rate, a 209% higher texture rate, and 167% more memory bandwidth. In the only head-to-head benchmark, it wins with a 46% score advantage. This makes it the clear choice for any workload that stresses the GPU, such as gaming, 3D rendering, or GPU-accelerated compute applications. Its larger 3 GB memory buffer and 192-bit bus also provide an advantage in scenarios with high-resolution textures or large datasets.

The AMD Radeon R5 M435, while losing on all performance fronts, has its own niche. As an IGP with a PCIe 3.0 x8 interface, it is designed for integration into systems where a discrete MXM module is not feasible. It has a higher boost clock (1030 MHz vs 797 MHz), which could provide an advantage in short, bursty workloads that do not saturate memory bandwidth or texture units. The data shows it is competitive within its own class, with a positive deltaPct against its nearest rivals like the AMD Radeon R7 M465 (0.3%) and Intel UHD Graphics 730 (-1.2%). For a user with a laptop that only supports an integrated GPU, the R5 M435 is a functional option, but the benchmark results clearly indicate it is a lower-performance tier than the GTX 770M. The GTX 770M is the winner for pure performance; the R5 M435 wins only in the context of system compatibility and lower power integration, though its TDP is not listed.
