AMD FirePro M4000 vs AMD Radeon HD 7730M Comparison

The Verdict

The recorded data separates these two mobile GPUs primarily through the Geekbench OpenCL benchmark. The AMD Radeon HD 7730M scores 6581, while the AMD FirePro M4000 scores 5537. That is an 18.9% lead for the HD 7730M, which translates into a clear performance advantage in the database's single measured workload. The FirePro M4000 does not win any head-to-head benchmark. For a user choosing strictly from this data, the HD 7730M is the faster part. The FirePro M4000, however, has a decisive memory advantage: it uses GDDR5 memory with a bandwidth of 64.00 GB/s, versus the HD 7730M's DDR3 memory at 28.80 GB/s. That bandwidth difference may matter for specific memory-bound tasks, but the OpenCL score still favors the HD 7730M. The FirePro M4000 also carries a professional mobile branding, which typically indicates different driver validation, but the benchmark data here does not reward it with higher performance. The verdict is straightforward: pick the HD 7730M for raw compute performance, and only consider the FirePro M4000 if its GDDR5 memory interface or MXM module form factor is a requirement for the target system.

Where Each One Wins

The AMD Radeon HD 7730M wins the only recorded head-to-head benchmark, Geekbench OpenCL, with a score of 6581 against 5537. That is an 18.9% victory, and it places the HD 7730M at the 38th percentile of all GPUs in the database. The FirePro M4000 sits at the 32nd percentile. The HD 7730M's nearest rivals in the database are Intel UHD Graphics P750 (6554, a 0.4% gap) and AMD Radeon R7 M460 (6612, a 0.5% gap). That means the HD 7730M is essentially tied with those two, while being 1% ahead of the NVIDIA GeForce GTX 670M and 1.4% ahead of the NVIDIA GeForce GT 555M. The FirePro M4000, by contrast, is 0.5% ahead of the NVIDIA GeForce MX130, 0.7% ahead of the NVIDIA GeForce GTX 765M, and 1% ahead of the AMD Radeon R7 M440. It trails the NVIDIA Quadro M500M by 1.2%. In terms of where each one wins, the HD 7730M wins in raw compute throughput as measured by OpenCL. The FirePro M4000 wins in memory bandwidth, with 64.00 GB/s versus 28.80 GB/s, and it also has a higher effective memory clock: 4 Gbps effective versus 1800 Mbps effective. That is not a benchmark win, but it is a measurable specification advantage. For gaming or general compute, the HD 7730M's higher OpenCL score is the relevant metric. For tasks that are heavily memory-bound, the FirePro M4000's GDDR5 bandwidth is the stronger asset, though no benchmark in the database confirms that advantage.

Architecture Differences

Both GPUs share the same chip, the Chelsea, and the same GCN 1.0 architecture. Both are manufactured on a 28 nm process at TSMC. Both have 1,500 million transistors and a die size of 123 mm², giving both a transistor density of 12.2M per mm². The shading units, texture mapping units, and ROPs are identical: 512 shading units, 32 TMUs, and 16 ROPs. The pixel rate and texture rate are also the same: 10.80 GPixel/s and 21.60 GTexel/s. FP32 compute is identical at 691.2 GFLOPS. The API support matches as well: DirectX 12 (11_1), OpenGL 4.6, and Vulkan 1.2.170. The core differences lie outside the compute core. The HD 7730M has a base clock of 575 MHz and a boost clock of 675 MHz. The FirePro M4000 has no recorded base or boost clock in the database, so its core clock is unspecified. The memory subsystem is where they diverge. The HD 7730M uses 2 GB of DDR3 on a 128-bit bus, with a memory clock of 900 MHz (1800 Mbps effective) and bandwidth of 28.80 GB/s. The FirePro M4000 uses 1024 MB of GDDR5 on the same 128-bit bus, with a memory clock of 1000 MHz (4 Gbps effective) and bandwidth of 64.00 GB/s. That is a 2.22x bandwidth advantage for the FirePro M4000. The form factors also differ: the HD 7730M is a portable device dependent part, while the FirePro M4000 is an MXM Module with no power connectors and a MXM-A (3.0) bus interface. The HD 7730M uses PCIe 2.0 x16. The TDP differs: 25 W for the HD 7730M versus 33 W for the FirePro M4000. The release dates are close: 2012-04-23 for the HD 7730M and 2012-06-26 for the FirePro M4000. The generations are different: London (HD 7700M) versus FirePro Mobile (Mx000). Both are end-of-life. The predecessors are different: Vancouver for the HD 7730M, FirePro Mobility for the M4000. The successors are also different: Solar System for the HD 7730M, Radeon Pro Mobile for the M4000.

Head-to-Head Benchmarks

The only recorded head-to-head benchmark is Geekbench OpenCL. The AMD Radeon HD 7730M scores 6581, and the AMD FirePro M4000 scores 5537. The HD 7730M wins by 18.9%. That is a substantial margin, especially considering that the two GPUs share the same chip, architecture, and compute core configuration. Both have 512 shading units, 32 TMUs, 16 ROPs, and identical FP32 throughput of 691.2 GFLOPS. The difference in OpenCL score therefore must be attributed to the core clocks and memory subsystem. The HD 7730M has a recorded base clock of 575 MHz and boost of 675 MHz. The FirePro M4000 has no recorded core clock, so the database does not confirm its operating frequency. The memory difference is stark: the FirePro M4000 has 64.00 GB/s of bandwidth versus 28.80 GB/s for the HD 7730M, a 2.22x advantage. Yet in OpenCL, that bandwidth advantage did not translate into a score win. The HD 7730M's higher core clocks and double the memory capacity (2 GB versus 1024 MB) appear to have been more influential in this workload. The percentile ranks confirm the gap: the HD 7730M sits at the 38th percentile of all GPUs, while the FirePro M4000 sits at the 32nd. That is a six-percentile-point difference, which aligns with the 18.9% score delta. For context, the HD 7730M's score of 6581 is nearly identical to the AMD Radeon R7 M460's 6612, a 0.5% gap, and it is 1% ahead of the NVIDIA GeForce GTX 670M. The FirePro M4000's score of 5537 is essentially tied with the NVIDIA GeForce MX130 (5508) and the NVIDIA GeForce GTX 765M (5501). The data shows that the HD 7730M competes in a slightly higher performance tier than the FirePro M4000, despite the latter's superior memory bandwidth. There are no other benchmark entries in the database, so the OpenCL result is the only quantitative comparison. The HD 7730M wins that comparison decisively.
