AMD Radeon R7 M365X vs AMD Radeon R7 M445 Comparison

The AMD Radeon R7 M365X edges out the AMD Radeon R7 M445 in the only directly comparable benchmark, but the two cards are separated by a razor-thin margin that places them in the same performance tier. The M365X posts an average benchmark score of 5416 against the M445’s 5358, a difference of just 1.1% in favor of the older card. Both GPUs sit in the bottom third of all graphics processors, with the M365X at the 32nd percentile and the M445 at the 31st percentile. The data shows two end-of-life mobile parts that are functionally interchangeable in raw compute, despite significant architectural differences under the hood.

Head-to-Head Benchmarks

The sole head-to-head result available is Geekbench OpenCL, where the AMD Radeon R7 M365X scores 5939 against the AMD Radeon R7 M445’s 5358. That translates to a 10.8% victory for the M365X, its only win in the comparison. This is a meaningful gap in a single test, but it does not reflect the broader average picture: when averaging all benchmarks, the M365X’s 5416 is only 1.1% above the M445’s 5358. The discrepancy between the single-test delta and the average delta suggests that the M365X performs disproportionately well in OpenCL workloads specifically, while other factors may narrow the gap in general compute.

Context from the nearest rivals reinforces how close these two are. The M365X’s closest competitor is the AMD Radeon 610M, which scores 5444 and trails the M365X by just 0.5%. The M445’s nearest rival is the Intel UHD Graphics P630 at 5370, which leads the M445 by 0.2%. In other words, both AMD parts are bracketed by integrated graphics solutions from AMD and Intel, and neither can pull away from the pack. The M365X also sits 0.9% behind the NVIDIA Quadro M4000 (5467) and 0.9% ahead of the M445 itself, while the M445 is 0.7% ahead of the NVIDIA GeForce 840M (5322) and 0.8% ahead of the NVIDIA GeForce 930A (5317). The performance clustering is tight enough that real-world differences would be imperceptible in most applications.

For the M445, the closest rival list includes the NVIDIA GeForce GTX 980M at 5308, which the M445 leads by 0.9%. That is a notable data point because the GTX 980M is generally considered a far more powerful part in other contexts, but in this benchmark suite the M445 holds a slim edge. The takeaway is that both AMD cards are firmly entry-level performers, and the 10.8% OpenCL win for the M365X is the only statistically meaningful separation in the entire dataset.

Architecture Differences

The two GPUs come from different generations of AMD’s Graphics Core Next architecture, which explains their divergent specifications. The AMD Radeon R7 M365X is built on GCN 1.0, uses the Litho chip, and belongs to the Gem System (R7 M300) generation. The AMD Radeon R7 M445, by contrast, uses GCN 3.0 with the Meso chip and belongs to the Gem System (R7 M400) generation. Both are fabricated on TSMC’s 28 nm process, but the transistor counts differ substantially: the M365X packs 950 million transistors on a 77 mm² die, while the M445 crams 1,550 million transistors onto a 125 mm² die. Transistor density is nearly identical at 12.3M / mm² for the M365X and 12.4M / mm² for the M445, reflecting the same manufacturing node.

The newer architecture gives the M445 a few notable feature advantages. It supports DirectX 12 (12_0), whereas the M365X is limited to DirectX 12 (11_1). Both cards support OpenGL 4.6 and Vulkan 1.2.170. The M445 also has explicit FP16 support at 588.8 GFLOPS (1:1), while the M365X has no listed FP16 capability. Clock speeds tell a different story: the M365X has no base or boost clock listed, but the M445 runs at a 780 MHz base and 920 MHz boost. Memory clocks are identical at 1000 MHz (4 Gbps effective), but the memory configurations diverge sharply. The M365X uses 1024 MB of GDDR5 on a 128-bit bus for 64.00 GB/s bandwidth, while the M445 uses 4 GB of GDDR5 on a 64-bit bus for just 32.00 GB/s bandwidth. The M445 has half the memory bandwidth of the M365X, which likely explains its lower OpenCL score despite the newer architecture.

Compute resource counts also favor the older part. The M365X has 384 shading units, 24 texture mapping units, and 8 ROPs. The M445 has 320 shading units, 20 TMUs, and 8 ROPs. Pixel rate is slightly higher on the M445 at 7.360 GPixel/s versus 6.600 GPixel/s, but texture rate is higher on the M365X at 19.80 GTexel/s versus 18.40 GTexel/s. FP32 performance is 633.6 GFLOPS for the M365X and 588.8 GFLOPS for the M445. The M365X’s larger shading unit count and wider memory bus give it a raw throughput advantage that the M445’s higher clocks and newer architecture cannot fully overcome.

The Verdict

The data points clearly to the AMD Radeon R7 M365X as the superior performer, but only by a modest margin. In the single head-to-head benchmark, the M365X wins with a 10.8% lead in Geekbench OpenCL. Its average benchmark score of 5416 is 1.1% higher than the M445’s 5358, and its percentile ranking is one point higher (32 vs 31). The M365X also holds advantages in shading units (384 vs 320), texture units (24 vs 20), FP32 throughput (633.6 vs 588.8 GFLOPS), and memory bandwidth (64.00 vs 32.00 GB/s). These are not trivial differences in specifications, and they translate into a measurable, if not dramatic, performance edge.

The M445 does have its own strengths. It is a newer part with GCN 3.0 architecture, supports DirectX 12 (12_0), and offers 4 GB of VRAM versus 1 GB on the M365X. It also has higher clock speeds (780 MHz base, 920 MHz boost) and a slightly better pixel rate (7.360 vs 6.600 GPixel/s). For users who need more video memory or require DirectX 12 (12_0) features, the M445 is the only choice between the two. However, the M365X’s superior memory bandwidth and compute throughput make it the better option for raw performance in OpenCL and likely in most GPU-bound tasks. Neither card is competitive by modern standards, but the M365X wins the direct comparison on every performance metric that matters.

Where Each One Wins

The AMD Radeon R7 M365X wins in raw compute and memory-bound scenarios. Its 64.00 GB/s memory bandwidth is double that of the M445, which gives it a decisive advantage in any workload that streams large amounts of texture or geometry data. The 10.8% OpenCL lead confirms this, and the higher FP32 throughput (633.6 vs 588.8 GFLOPS) makes it the stronger choice for general-purpose compute on the GPU. With 384 shading units and 24 TMUs, it also has more parallel execution resources for shader-heavy rendering. The M365X is the pick for users who prioritize frame rates and compute performance over feature support.

The AMD Radeon R7 M445 wins in capacity and compatibility. Its 4 GB of VRAM is four times the M365X’s 1 GB, which matters for modern games and applications that exceed 1 GB of video memory. The newer GCN 3.0 architecture brings DirectX 12 (12_0) support, enabling features that the M365X cannot access under that API. The M445 also has higher base and boost clocks (780 MHz / 920 MHz) and a better pixel rate (7.360 vs 6.600 GPixel/s), giving it a slight edge in fill-rate-limited scenarios. For users who need more memory, newer API support, or an integrated form factor (the M445 is listed as IGP slot width), the M445 is the appropriate choice despite its lower raw performance.
