AMD Radeon R7 M445 vs AMD Radeon R7 M465 Comparison

Where Each One Wins

The benchmark data splits cleanly between these two mobile graphics parts, and the distinction comes down to compute throughput versus memory capacity. The AMD Radeon R7 M465 takes the single recorded benchmark victory, the Geekbench OpenCL test, with a score of 5841 against the R7 M445's 5358. That is a 9% advantage, and it is the only head-to-head comparison recorded in the database. The M465 wins the compute-oriented workload outright.

The AMD Radeon R7 M445, on the other hand, does not win any recorded benchmark. Its wins, if they exist in real-world usage, would have to come from areas not captured by the Geekbench OpenCL test. The database shows zero wins for the M445 in the head-to-head comparison. What the M445 does offer is a larger memory pool: 4 GB of GDDR5 versus 2 GB on the M465. That capacity advantage does not translate into a compute score win, but it could matter for workloads that need to hold larger datasets in video memory. The recorded data, however, does not include a test that isolates memory capacity benefits, so this remains an inference from the specification differences rather than a measured result.

Breaking down the compute scores further, the M465 sits at the 33rd percentile among all GPUs in the database, while the M445 sits at the 31st percentile. Both are low-end parts by this measure, but the M465 is slightly higher. The M465's nearest rivals include the AMD Radeon R5 M435 (average score 5859, delta -0.3%), the Intel UHD Graphics 730 (5929, delta -1.5%), the NVIDIA GeForce GTX 550 Ti (5731, delta 1.9%), and the AMD Radeon HD 8730M (5955, delta -1.9%). The M465 is essentially tied with the R5 M435, within 0.3% of it. It trails the Intel UHD Graphics 730 by 1.5% and the Radeon HD 8730M by 1.9%, but it beats the older GeForce GTX 550 Ti by 1.9%.

The M445's nearest rivals paint a similar picture. It is within 0.2% of the Intel UHD Graphics P630 (5370), 0.7% ahead of the NVIDIA GeForce 840M (5322), 0.8% ahead of the NVIDIA GeForce 930A (5317), and 0.9% ahead of the NVIDIA GeForce GTX 980M (5308). That last comparison is curious: the GTX 980M, a high-end notebook part from a different era, scores lower in this particular OpenCL test than the M445 does. The data shows the M445 edges out the GTX 980M by 0.9%, though that likely reflects the specific compute workload and driver state at the time of measurement.

In terms of where each part wins, the M465 is the compute leader in the recorded data. The M445 offers more memory but no benchmark victories. The M465 also has higher shading unit count, higher texture units, higher clock speeds for boost and memory, and higher theoretical pixel and texture rates. All of those favor the M465 in compute-heavy tasks, which is exactly what Geekbench OpenCL measures.

The M445's only potential advantage, its 4 GB memory size, is not represented in any benchmark score in the database. So while the use-case split is straightforward: the M465 wins the compute test, and the M445 has no recorded wins.

The Verdict

From the recorded data, the AMD Radeon R7 M465 is the faster part. It wins the only head-to-head benchmark by 9%, with a score of 5841 versus 5358. Its percentile ranking is also higher, 33rd versus 31st. Anyone choosing between these two strictly on measured performance should pick the M465.

The AMD Radeon R7 M445, however, is not without reason to exist. It offers 4 GB of GDDR5 memory, double the M465's 2 GB. For users who need to load larger textures or datasets into video memory, the M445 might be the better fit despite its lower compute performance. The data does not quantify this advantage, and the M445 has zero benchmark wins, but the specification difference is clear. The M465 is the compute winner, the M445 is the memory capacity option.

The M445 also features a lower boost clock (920 MHz versus 5801 MHz base on the M465) and lower memory clock (1000 MHz, 4 Gbps effective versus 1125 MHz, 4.5 Gbps effective on the M465). The M465's boost clock of 1024 MHz exceeds the M445's 920 MHz, and the M465's memory clock is higher as well. The M465's base clock of 730 MHz is lower than the M445's 780 MHz, which is a small oddity, but the boost clock matters more for performance. The M465's memory bandwidth of 36.00 GB/s beats the M445's 32.00 GB/s. The M465 also leads in texture rate (24.58 GTexel/s versus 18.40 GTexel/s) and pixel rate (8.192 GPixel/s versus 7.360 GPixel/s). The M465's FP32 performance is 786.4 GFLOPS versus 588.8 GFLOPS on the M445, a substantial gap. The M465's shading unit count of 384 versus 320 and texture units of 24 versus 20 give it more parallel hardware.

The M465 is also marked as a discrete-style part while the M445 is labeled "IGP" in slot width, indicating it is integrated into a portable device. Both are end-of-life products with the same release date of 2016-05-14. Both share the same GCN 3.0 architecture, 28 nm process node, TSMC foundry, 1,550 million transistors, 125 mm² die size, and 12.4M / mm² transistor density. Both use PCIe 3.0 x8. Both support DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.2.170. The M445's display outputs are "Portable Device Dependent", while the M465's are not listed.

In summary, the M465 is the better performer according to the database. The M445 is the higher-capacity memory option. The M465 wins on compute, the M445 wins on memory size.

Head-to-Head Benchmarks

The only recorded head-to-head benchmark is Geekbench OpenCL. The AMD Radeon R7 M465 scores 5841, the AMD Radeon R7 M445 scores 5358. The delta is 9%, with the M465 as the winner. This is a meaningful margin in the low-end mobile GPU space. To put it in context, the M465's nearest rival, the AMD Radeon R5 M435, scores 5859, only 0.3% higher than the M465. The M445's nearest rival, the Intel UHD Graphics P630, scores 5370, only 0.2% higher than the M445. So the 9% gap between the two R7 parts is much larger than the gaps to their respective nearest neighbors.

The M465's score of 5841 places it ahead of the NVIDIA GeForce GTX 550 Ti (5731) by 1.9% and behind the AMD Radeon HD 8730M (5955) by 1.9%. The M445's score of 5358 places it ahead of the NVIDIA GeForce 840M (5322) by 0.7%, the NVIDIA GeForce 930A (5317) by 0.8%, and the NVIDIA GeForce GTX 980M (5308) by 0.9%. The M445 trails the Intel UHD Graphics P630 by 0.2%. These relative positions show that both parts are clustered in the same performance tier, but the M465 sits at the top of that cluster while the M445 sits at the bottom.

The 9% delta in the head-to-head test is larger than any delta between either part and its nearest rivals. That suggests the M465's advantage over the M445 is not noise. The M465 has 384 shading units versus 320, 24 TMUs versus 20, and a higher boost clock of 1024 MHz versus 920 MHz. Its FP32 throughput is 786.4 GFLOPS versus 588.8 GFLOPS, which is a 33.6% advantage in raw compute. The actual benchmark delta of 9% is smaller than the theoretical FP32 gap, indicating that memory bandwidth or other bottlenecks limit the M465's real-world advantage. The M465's memory bandwidth is 36.00 GB/s versus 32.00 GB/s, only 12.5% higher.

The M465's memory clock is 1125 MHz (4.5 Gbps effective) versus 1000 MHz (4 Gbps effective) on the M445. Both use a 64-bit bus, so the bandwidth difference comes entirely from the higher memory clock. The M445 compensates with 4 GB of memory versus 2 GB. In a compute test like OpenCL, capacity rarely matters, which helps explain why the M465 wins. The data shows the M465 wins the only recorded benchmark.
