AMD Radeon R7 Graphics vs AMD Radeon R7 M445 Comparison

# Head-to-Head Benchmarks

The benchmark data reveals a clear single-test advantage for the AMD Radeon R7 M445 over the AMD Radeon R7 Graphics. In the only directly comparable head-to-head test — Geekbench OpenCL — the M445 scores 5,358 points against the R7 Graphics' 4,015 points. That is a 33.4% delta in favor of the discrete mobile part, a decisive margin that effectively defines the competitive relationship between these two GPUs. The R7 Graphics wins zero head-to-head tests; the M445 wins one.

Looking at the broader benchmark landscape, the M445's OpenCL score places it at the 31st percentile among all GPUs, while the R7 Graphics sits at the 29th percentile. The gap is narrow in percentile terms, but the raw score difference tells a more assertive story. The M445's 5,358 OpenCL result lands it within 0.2% of the Intel UHD Graphics P630 (5,370), 0.7% ahead of the NVIDIA GeForce 840M (5,322), 0.8% ahead of the NVIDIA GeForce 930A (5,317), and 0.9% ahead of the NVIDIA GeForce GTX 980M (5,308). These are tight margins, suggesting the M445 competes in a crowded mid-pack where small score swings determine rank.

The R7 Graphics, by contrast, posts a 4,015 OpenCL score but also has a separate Vulkan result of 5,980 — a figure that is not directly comparable to the M445, since the M445 has no Vulkan benchmark entry in this dataset. Its average benchmark score across both tests is 4,998, which places it within 0.4% of the NVIDIA Quadro 4000 (4,979), 0.4% behind the AMD Radeon R5 M430 (5,018), 0.6% ahead of the NVIDIA GeForce RTX 5060 Ti 16 GB (4,970), and 0.7% behind the AMD FirePro W4170M (5,034). The R7 Graphics' OpenCL score alone is 33.4% lower than the M445's, a chasm that no amount of Vulkan performance can fully bridge in direct comparison.

# Architecture Differences

The two GPUs come from different architectural generations despite sharing the AMD brand and the 28 nm process node. The AMD Radeon R7 M445 is built on GCN 3.0 architecture using a chip codenamed Meso, and it belongs to the Gem System (R7 M400) generation. Its predecessor is listed as Solar System, and its successor is Polaris Mobile. The AMD Radeon R7 Graphics, meanwhile, uses GCN 2.0 architecture with a chip called Spectre Lite, part of the GCN 2.0 IGP (Kaveri) generation. Its predecessor is TeraScale 3 IGP, and its successor is GCN 3.0 IGP.

The manufacturing foundries differ as well. The M445 is fabricated by TSMC, while the R7 Graphics comes from GlobalFoundries. This distinction matters because the transistor densities diverge notably: the M445 packs 1,550 million transistors into a 125 mm² die, yielding a density of 12.4 million transistors per square millimeter. The R7 Graphics crams 2,410 million transistors into a 245 mm² die, which works out to 9.8 million per square millimeter. The M445 is thus the denser chip, despite having fewer total transistors.

Shader resources also differ. The R7 Graphics fields 384 shading units and 24 texture mapping units, while the M445 has 320 shading units and 20 TMUs. Both have 8 ROPs. The raw compute throughput tells a nuanced story: the M445 achieves 588.8 GFLOPS of FP32 performance, while the R7 Graphics posts 553.0 GFLOPS. The M445 also lists FP16 performance at 588.8 GFLOPS (1:1 ratio), whereas the R7 Graphics has no FP16 figure in the data.

The M445's pixel rate is 7.360 GPixel/s and its texture rate is 18.40 GTexel/s. The R7 Graphics' pixel rate is 5.760 GPixel/s and its texture rate is 17.28 GTexel/s. So the M445 leads in both fill-rate metrics, even though it has fewer TMUs. Clock behavior is another differentiator: the M445 has explicit base and boost clocks of 780 MHz and 920 MHz, respectively, while the R7 Graphics lists no base or boost clock at all — a reflection of its integrated nature where clocks are system-dependent.

# Specification Differences

The specification table shows several fields where these two GPUs diverge. The M445 uses the Meso chip with GCN 3.0 architecture, while the R7 Graphics uses Spectre Lite with GCN 2.0. The M445 is fabricated by TSMC; the R7 Graphics is made by GlobalFoundries. The M445 has 1,550 million transistors on a 125 mm² die; the R7 Graphics has 2,410 million on 245 mm². Transistor density is 12.4M per mm² for the M445 versus 9.8M per mm² for the R7 Graphics.

Clocks differ: the M445 runs at a 780 MHz base and 920 MHz boost, with memory at 1000 MHz (4 Gbps effective), while the R7 Graphics has no listed clocks and uses system shared memory. Memory specifications are entirely different: the M445 has 4 GB of GDDR5 on a 64-bit bus with 32.00 GB/s bandwidth, whereas the R7 Graphics has system-shared memory with system-dependent bandwidth. Shading units are 320 for the M445 versus 384 for the R7 Graphics; TMUs are 20 versus 24; ROPs are the same at 8.

Pixel rates are 7.360 GPixel/s for the M445 and 5.760 GPixel/s for the R7 Graphics. Texture rates are 18.40 GTexel/s versus 17.28 GTexel/s. FP32 compute is 588.8 GFLOPS for the M445 and 553.0 GFLOPS for the R7 Graphics. The M445 has FP16 at 588.8 GFLOPS (1:1); the R7 Graphics has no FP16 listing. The R7 Graphics has a TDP of 25 W, while the M445 has no TDP specified. The bus interface is PCIe 3.0 x8 for the M445 and IGP for the R7 Graphics. Display outputs are portable-device-dependent for the M445 and motherboard-dependent for the R7 Graphics. Release dates are 2016-05-14 for the M445 and 2014-02-16 for the R7 Graphics.

# The Verdict

The data points to a straightforward conclusion: the AMD Radeon R7 M445 is the faster GPU in direct compute workloads. Its 33.4% OpenCL lead over the R7 Graphics is the single most important benchmark statistic in this comparison, and it aligns with the M445's advantages in FP32 throughput, pixel rate, and texture rate. The M445 also benefits from dedicated GDDR5 memory with 32.00 GB/s bandwidth, whereas the R7 Graphics is constrained by system-shared memory and system-dependent bandwidth — a structural limitation that dedicated VRAM avoids.

However, the R7 Graphics is not without merit. It has more shading units (384 versus 320) and more TMUs (24 versus 20), which suggests it could handle certain workloads differently despite its lower overall compute numbers. Its Vulkan score of 5,980 is the highest single benchmark result in this comparison, though it cannot be matched against the M445 because the M445 lacks a Vulkan entry. The R7 Graphics also has a clearly defined 25 W TDP, making it a known quantity for power-constrained integrated designs.

The percentile rankings are close — 31st for the M445 and 29th for the R7 Graphics — but the raw score gap is not close at all. Buyers or system builders choosing between a discrete M445 and an integrated R7 Graphics should prioritize the M445 for compute-heavy tasks like OpenCL acceleration. The R7 Graphics' Vulkan performance might appeal to specific software stacks, but the absence of a direct Vulkan comparison means that advantage is unproven against the M445. The verdict from the data: the M445 wins on measured performance, with the R7 Graphics offering only architectural diversity — more shaders, a larger die, and a known power envelope — as counterpoints.

# Where Each One Wins

The AMD Radeon R7 M445 wins in raw OpenCL compute performance, posting 5,358 points versus 4,015 for the R7 Graphics — a 33.4% advantage. It also leads in FP32 throughput (588.8 GFLOPS vs 553.0 GFLOPS), pixel fill rate (7.360 GPixel/s vs 5.760 GPixel/s), and texture fill rate (18.40 GTexel/s vs 17.28 GTexel/s). The M445's dedicated 4 GB GDDR5 memory with 32.00 GB/s bandwidth is a clear win over system-shared memory, eliminating contention with the CPU for memory access. Its higher transistor density (12.4M per mm² vs 9.8M per mm²) also indicates a more efficient use of silicon area.

The AMD Radeon R7 Graphics wins in shader count (384 vs 320) and TMU count (24 vs 20), which could translate to better performance in workloads that scale with parallel execution units rather than clock speed or memory bandwidth. Its Vulkan score of 5,980 is the highest single benchmark figure in this comparison, though it lacks a direct rival score from the M445. The R7 Graphics also has a larger die (245 mm² vs 125 mm²) and more transistors (2,410 million vs 1,550 million), which may indicate broader feature integration for an IGP. Its 25 W TDP is explicitly documented, whereas the M445 has no TDP listed, making the R7 Graphics a more predictable choice for thermally constrained integrated systems.

For use-case selection, the M445 is the pick for OpenCL-accelerated applications, dedicated graphics memory needs, and scenarios where discrete PCIe connectivity (PCIe 3.0 x8) is available. The R7 Graphics suits integrated builds where motherboard-dependent output and system-shared memory are acceptable, and where Vulkan performance is a priority. The data does not support a scenario where the R7 Graphics outperforms the M445 in a directly comparable test — the M445 wins the only head-to-head benchmark — so any R7 Graphics advantage is speculative outside its unverified Vulkan result.
