Q: Which GPU has a higher boost clock?

A: The R5 M435 has a boost clock of 1030 MHz, which is higher than the R7 M370's boost clock of 960 MHz. However, the R7 M370 has a higher base clock at 875 MHz versus 780 MHz.

Architecture Differences

Both GPUs are built on AMD's GCN 1.0 architecture and manufactured on a 28 nm process at TSMC. The transistor density is identical at 12.3M per square millimeter, reflecting the shared process generation. However, the underlying chips differ significantly in scale.

The R7 M370 uses the Litho chip, which contains 950 million transistors on a 77 mm² die. The R5 M435 uses the Jet chip, housing 690 million transistors on a 56 mm² die. This difference in transistor count translates directly to compute resources: the R7 M370 has 384 shading units, 24 texture mapping units, and 8 ROPs, while the R5 M435 has 320 shading units, 20 TMUs, and 8 ROPs. The ROP count is identical, but the R7 M370 has 20% more shaders and TMUs.

Memory architecture differs substantially. The R7 M370 operates a 128-bit memory bus with GDDR5 running at 900 MHz (3.6 Gbps effective), yielding 57.60 GB/s of bandwidth. The R5 M435 uses a 64-bit bus with GDDR5 at 1125 MHz (4.5 Gbps effective), producing 36.00 GB/s. Despite the R5 M435's higher memory clock, the narrower bus halves the possible bandwidth, leaving it well behind.

Clock behavior also diverges. The R7 M370 has a base clock of 875 MHz and a boost of 960 MHz. The R5 M435 starts lower at 780 MHz but boosts higher to 1030 MHz. This means at peak boost, the R5 M435 runs faster per clock, but its fewer shaders and reduced memory bandwidth limit overall throughput.

Both GPUs share the same PCIe 3.0 x8 bus interface, and neither has a defined TDP in the database. The R5 M435 is classified as an IGP (integrated graphics processor) with portable-device-dependent display outputs, while the R7 M370 does not have a slot width or display output specification listed.

Head-to-Head Benchmarks

The database contains one head-to-head benchmark between these two GPUs: geekbench_opencl. In this test, the R7 M370 scores 7063 against the R5 M435's 5859, a delta of 20.5%. This is a decisive win for the R7 M370, and the margin is substantial for two GPUs in the same product family.

Placing these scores in context, the R7 M370's 7063 OpenCL result puts it above its nearest rival, the NVIDIA GeForce GT 1010, by 1% (score 6698). It also trails the AMD FirePro M5100 by 1% (score 6830) and the NVIDIA GeForce GTX 675M by 2.6% (score 6946). Meanwhile, the R5 M435's 5859 score sits just below the Intel UHD Graphics 730 (5929, 1.2% ahead) and the AMD Radeon HD 8730M (5955, 1.6% ahead). It is only 0.3% ahead of the AMD Radeon R7 M465 (5841).

The 20.5% performance gap between the two reviewed GPUs is larger than the differences seen between either GPU and its respective nearest rivals. This suggests the R7 M370 and R5 M435 occupy distinct performance tiers, with the R7 M370 closer to mid-range mobile discrete GPUs and the R5 M435 nearer to entry-level integrated-class solutions.

In terms of aggregate metrics, the R7 M370's average benchmark score of 6764 is 15.4% higher than the R5 M435's 5859. The percentile ranking also separates them: 38th percentile versus 33rd percentile. While both sit in the lower-middle range of all GPUs, the R7 M370 is consistently positioned above its sibling.

The Verdict

The data clearly favors the AMD Radeon R7 M370. It wins the only direct head-to-head benchmark by 20.5%, has a higher average score (6764 versus 5859), and ranks five percentile points higher. Its 128-bit memory bus and 57.60 GB/s bandwidth provide a substantial advantage over the R5 M435's 64-bit bus and 36.00 GB/s.

The R5 M435 does have a higher boost clock (1030 MHz versus 960 MHz) and a faster effective memory clock (4.5 Gbps versus 3.6 Gbps), but these do not compensate for its fewer shading units (320 versus 384) and narrower memory path. The result is a GPU that consistently trails its sibling in compute workloads.

For users choosing between these two, the R7 M370 is the stronger pick for any OpenCL-based task, including general compute, image processing, or GPU-accelerated applications. The R5 M435, with its lower transistor count and reduced bandwidth, is suited only for lighter workloads where the performance delta may not be critical. Given that both are end-of-life products, the data simply records that the R7 M370 is the more capable part.

• Transistor count: 950 million versus 690 million

AMD Radeon R5 M435 wins in:

• Boost clock: 1030 MHz versus 960 MHz, a 7.3% advantage
• Base clock efficiency per MHz: it reaches a higher peak frequency
• Pixel rate: 8.240 GPixel/s versus 7.680 GPixel/s, a 7.3% advantage
• Memory clock: 1125 MHz versus 900 MHz, a 25% advantage on the memory clock itself (though the narrower bus negates this)
• Release date: launched later on 2016-05-14 versus 2015-05-04

The R5 M435's pixel rate win is notable because it has the same ROP count (8) but a higher boost clock, allowing faster pixel output despite fewer shading resources. However, this single metric does not offset the R7 M370's broad lead in compute, bandwidth, and texture throughput. Users prioritizing raw compute should select the R7 M370; those with pixel-bound workloads might find the R5 M435's higher clock useful, but the overall benchmark data favors the R7 M370 in every measured test.
