AMD Radeon R7 M440 vs AMD Radeon R7 M445 Comparison

Head-to-Head Benchmarks

The only directly comparable benchmark in the data is Geekbench OpenCL, and it produces a clear, if modest, winner. The AMD Radeon R7 M445 scores 5358, while the AMD Radeon R7 M440 scores 5214. That is a 2.7% advantage for the M445, which is not a dramatic gap but is consistent across the board when you look at the underlying specifications that drive that score. In a single head-to-head comparison, the M445 takes the win, giving it a 1-0 record in direct matchups.

That 2.7% lead in OpenCL is worth putting into context. The M445's average benchmark score of 5358 places it at the 31st percentile of all GPUs. Its nearest rivals include the Intel UHD Graphics P630 at 5370 (a 0.2% gap against the M445) and the NVIDIA GeForce 840M at 5322. The M445 beats the 840M by 0.7% and the GeForce 930A by 0.8%. It even edges out the GeForce GTX 980M on average score by 0.9%, though that delta is within normal run-to-run variance. The picture is one of a card sitting in a very crowded mid-low tier, where a few percent separates dozens of products.

The R7 M440, meanwhile, posts an average benchmark score of 5483, which is actually higher than the M445's 5358. That seems contradictory given the head-to-head result, but it is explained by the M440 having a second benchmark result in the data: a Geekbench Vulkan score of 5751 alongside its OpenCL score of 5214. Averaging those two yields 5483. The M445 only has the single OpenCL result of 5358, so its average is just that number. This is a classic case where a single-test comparison and a multi-test average tell different stories. If you weight only OpenCL, the M445 wins by 2.7%; if you look at overall average across available tests, the M440 comes out ahead by about 2.3%.

The M440's percentile ranking reflects that broader average: it sits at the 32nd percentile, one point higher than the M445's 31st. Its nearest rivals include the NVIDIA Quadro M4000 at 5467 (a 0.3% delta), the GeForce GTX 765M at 5501 (a 0.3% delta in the other direction), and the GeForce MX130 at 5508. The M440 also edges out the AMD Radeon 610M by 0.7%. What is striking is that both cards are bracketed by essentially the same class of competition: low-end discrete and integrated solutions that all land within a few percentage points of each other.

The single head-to-head result is the only direct evidence we have, and it favors the M445. But the broader benchmark picture suggests that the two cards are effectively interchangeable in raw compute performance. A 2.7% delta in OpenCL is the kind of margin that could flip with driver updates or thermal conditions in a laptop chassis. The Vulkan result for the M440, however, hints that it may have an edge in that specific API, though we cannot verify that against the M445 since no Vulkan score exists for it.

The Verdict

If you are choosing strictly on the data presented, the AMD Radeon R7 M445 wins the only direct head-to-head benchmark available. Its OpenCL score of 5358 beats the M440's 5214 by 2.7%. That is the single most defensible statement you can make from this fact pack. The M445 also has a higher base clock (780 MHz vs. no listed base clock for the M440) and a higher boost clock (920 MHz vs. no listed boost clock). It uses faster GDDR5 memory clocked at 1000 MHz with 4 Gbps effective throughput, delivering 32.00 GB/s of bandwidth. The M440, by contrast, uses DDR3 at 900 MHz with 1800 Mbps effective, yielding only 14.40 GB/s. That memory bandwidth difference — more than double — is likely the primary driver of the M445's OpenCL win.

However, the M440 has a counterargument. Its average benchmark score across two tests is 5483, which is higher than the M445's 5358. That average is pulled up by its Vulkan score of 5751. If you expect to run applications that leverage Vulkan, the M440 appears to have an advantage, though the absence of a Vulkan score for the M445 makes this an inference rather than a proven result. The M440 also holds a slightly higher percentile rank (32nd vs. 31st), which reflects that multi-test average.

Who should pick which? If your workload is OpenCL-heavy — which covers many compute tasks and some older game engines — the M445 is the safer bet. The 2.7% lead is small, but it is a real measured difference. If you care about Vulkan performance or want the higher average score across multiple APIs, the M440 is the one to go with. For gaming specifically, neither card is a powerhouse; both sit in the low 30s percentile band, meaning they are outclassed by roughly two-thirds of all GPUs. But between the two, the M445's superior memory bandwidth gives it a tangible edge in texture-heavy scenarios, even at the same 320 shading units, 20 TMUs, and 8 ROPs.

Specification Differences

The two cards share a great deal of core architecture, but the memory subsystem and clock speeds set them apart. The R7 M445 is clocked at 780 MHz base and 920 MHz boost, while the R7 M440 has no base or boost clock listed. The memory clocks differ substantially: the M440 runs DDR3 at 900 MHz with 1800 Mbps effective throughput, while the M445 runs GDDR5 at 1000 MHz with 4 Gbps effective throughput. This yields a bandwidth of 14.40 GB/s for the M440 versus 32.00 GB/s for the M445 — a 122% advantage for the M445. Both cards have 4 GB of memory on a 64-bit bus.

The compute rates reflect the clock differences. The M440 achieves a pixel rate of 7.128 GPixel/s and a texture rate of 17.82 GTexel/s, with FP32 performance of 570.2 GFLOPS. The M445 is slightly ahead: 7.360 GPixel/s, 18.40 GTexel/s, and 588.8 GFLOPS. These are small margins — about 3% — but they align with the 2.7% OpenCL benchmark delta. Both cards report FP16 at the same rate as FP32 (1:1), which is notable for a GCN 3.0 part.

Other differences are minimal. Both use a PCIe 3.0 x8 bus interface, both are listed as IGP slot width with portable-device-dependent display outputs, and both support DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.2.170. Neither has a TDP listed, power connector info, or a suggested PSU. Both are end-of-life products released on the same date.

Architecture Differences

Architecturally, these are essentially the same GPU. Both are built on the Meso chip using GCN 3.0 architecture, fabricated on a 28 nm process at TSMC. Both have 1,550 million transistors on a 125 mm² die, yielding a transistor density of 12.4 million per square millimeter. They belong to the same generation (Gem System, R7 M400 series) and share the same predecessor (Solar System) and successor (Polaris Mobile).

The shading core is identical: 320 shading units, 20 TMUs, and 8 ROPs. Neither has ray tracing cores or tensor cores. The API support is identical across DirectX, OpenGL, and Vulkan. The only meaningful architectural differences are in the memory type (DDR3 vs. GDDR5) and the associated clock speeds. The M445's GDDR5 memory operates at a higher frequency and delivers more than double the bandwidth of the M440's DDR3. This is the kind of difference that can matter in memory-bound workloads, even when the compute core is the same.

The lack of a base or boost clock for the M440 in the data suggests it may be a lower-binned part or that AMD did not publicize those figures for this variant. The M445's clocks are modest by modern standards, but they are at least documented. The FP32 and FP16 performance being equal (1:1 ratio) indicates these chips do not have dedicated half-rate FP16 paths, which is consistent with GCN 3.0's design priorities.

Where Each One Wins

AMD Radeon R7 M445 wins in: OpenCL compute workloads. The measured 2.7% lead in Geekbench OpenCL is the only direct benchmark win in the data. The M445's higher clocks (780 MHz base, 920 MHz boost) and dramatically higher memory bandwidth (32.00 GB/s vs. 14.40 GB/s) give it a tangible edge in any task that saturates memory bandwidth. This includes texture-heavy game scenes, higher-resolution frame buffers, and compute kernels that stream large datasets. The M445 also has slightly higher pixel and texture rates, which translate to better fill-rate performance in rasterization-bound scenarios. If you are running OpenCL-based applications like certain physics simulations, video encoding tools, or older game engines that rely on OpenCL compute, the M445 is the pick.

AMD Radeon R7 M440 wins in: Cross-API average performance and Vulkan-specific workloads. The M440's Geekbench Vulkan score of 5751 is the single highest benchmark result in this entire comparison, and it lifts the card's average to 5483 — above the M445's 5358. The M440 also holds a higher percentile rank (32nd vs. 31st), which is a direct consequence of that Vulkan performance. If you use applications that leverage Vulkan — modern game engines, some emulators, and certain professional visualization tools — the M440 appears to have the advantage, though the lack of a Vulkan score for the M445 means this is an inference from the available data rather than a direct comparison. The M440's lower memory bandwidth (14.40 GB/s) does not seem to hamper it in Vulkan, which may indicate that the workload is more compute-bound than memory-bound in that API.

Tie situations: For pure gaming at typical laptop resolutions, the two cards are close enough that the differences are unlikely to be perceptible. Both sit in the low 30s percentile band, meaning they are entry-level parts. The 320 shading units and 8 ROPs are identical, so the core compute throughput is nearly the same. The M445's memory advantage will show up in some scenarios, but the M440's Vulkan strength will show up in others. If you are deciding between two laptops that each have one of these GPUs, the M445 is the safer default choice due to its direct benchmark win and memory bandwidth. But if the M440-equipped system costs the same and you know your software uses Vulkan, the data suggests you are not losing much — and you might even gain a few points in average performance.
