AMD Radeon HD 8750M vs AMD Radeon Vega 10 Mobile Comparison

Where Each One Wins

The benchmark data splits cleanly between these two mobile graphics parts, with the AMD Radeon Vega 10 Mobile taking the only recorded head-to-head victory. In the Geekbench OpenCL test, the Vega 10 Mobile scores 6476 against the HD 8750M's 5970, a delta of 8.5 percent. That single win defines the entire comparison, as the database records no test where the HD 8750M comes out ahead.

The Vega 10 Mobile's win is not just about raw score, it also sits higher in the overall GPU distribution. Its percentile rank is 37, meaning it outperforms 37 percent of all GPUs in the database, while the HD 8750M sits at 34. The three point gap in percentiles reflects the 8.5 percent score advantage, and neither part is near the top of the stack. Both are positioned as entry level or legacy mobile solutions, which the data confirms through their end-of-life production status.

The use case split is therefore straightforward: the Vega 10 Mobile is the stronger compute performer in OpenCL workloads, while the HD 8750M trails by a modest margin. The HD 8750M does not win any recorded benchmark, so its case rests entirely on architectural differences and feature support rather than measured performance. For users running OpenCL accelerated tasks, the data points squarely at the Vega 10 Mobile. For those considering the HD 8750M, the recorded measurements offer no category where it leads.

Architecture Differences

The two GPUs come from different generations of AMD's Graphics Core Next architecture, and the gap in process technology is substantial. The Vega 10 Mobile uses GCN 5.0 on a 14 nm process from GlobalFoundries, while the HD 8750M uses GCN 1.0 on a 28 nm process from TSMC. That process shrink is one of the largest single differences between the two, and it shows up in transistor density: the Vega 10 Mobile packs 23.5 million transistors per square millimeter versus 12.3 million for the HD 8750M.

The chip scale difference is dramatic as well. The Vega 10 Mobile's Raven-M chip contains 4,940 million transistors on a 210 mm² die, while the HD 8750M's Mars chip contains 950 million transistors on a 77 mm² die. The Vega 10 Mobile has more than five times the transistor count on nearly three times the die area, which explains its much larger compute resource pool. The HD 8750M's simpler GCN 1.0 design uses fewer transistors but also draws less complexity from its older architecture generation.

Compute resources differ sharply. The Vega 10 Mobile has 640 shading units, 40 texture mapping units, and 8 ROPs, while the HD 8750M has 384 shading units, 24 TMUs, and 8 ROPs. The shading unit count is 66.7 percent higher on the Vega 10 Mobile, and the TMU count is 66.7 percent higher as well. ROP counts are identical at 8, meaning pixel output capability is not the differentiator. The Vega 10 Mobile's pixel rate is 10.41 GPixel/s versus 6.600 GPixel/s for the HD 8750M, and its texture rate is 52.04 GTexel/s versus 19.80 GTexel/s. FP32 throughput is 1.665 TFLOPS against 633.6 GFLOPS, a 2.6x advantage. The Vega 10 Mobile also supports FP16 at 3.331 TFLOPS with a 2:1 ratio, while the HD 8750M has no recorded FP16 capability.

Memory architecture is another major divergence. The Vega 10 Mobile uses system shared memory with no dedicated VRAM, and its bandwidth is listed as system dependent. The HD 8750M has 1024 MB of dedicated DDR3 memory on a 128 bit bus with 28.80 GB/s of bandwidth. The Vega 10 Mobile's memory clock is also listed as system shared, while the HD 8750M runs at 900 MHz with 1800 Mbps effective. This means the Vega 10 Mobile's performance depends heavily on the host system's memory subsystem, whereas the HD 8750M has predictable, fixed bandwidth.

API support differs in small but measurable ways. Both support DirectX 12, but the Vega 10 Mobile reaches feature level 12_1 while the HD 8750M is limited to 11_1. Both support OpenGL 4.6. Vulkan support is close: 1.3 on the Vega 10 Mobile versus 1.2.170 on the HD 8750M. The bus interface also differs, with the Vega 10 Mobile being an integrated GPU (IGP) and the HD 8750M using PCIe 3.0 x8. The Vega 10 Mobile reports a 10 W TDP and requires no power connectors, while the HD 8750M has no TDP or power connector data recorded.

Specification Differences

The specification sheet reveals two fundamentally different designs. The Vega 10 Mobile is a 14 nm integrated GPU from the GCN 5.0 generation, using the Raven-M chip with 4,940 million transistors on a 210 mm² die. The HD 8750M is a 28 nm discrete GPU from the GCN 1.0 generation, using the Mars chip with 950 million transistors on a 77 mm² die. Transistor density is 23.5M per mm² for the Vega 10 Mobile versus 12.3M per mm² for the HD 8750M.

Clock speeds show a striking inversion. The Vega 10 Mobile has a 300 MHz base clock and a 1301 MHz boost clock, while the HD 8750M has a 775 MHz base clock and an 825 MHz boost clock. The Vega 10 Mobile's boost clock is 57.7 percent higher, but its base clock is much lower. The HD 8750M's memory runs at 900 MHz with 1800 Mbps effective, while the Vega 10 Mobile's memory is system shared.

Compute unit counts differ across the board: 640 shading units versus 384, 40 TMUs versus 24, and 8 ROPs versus 8. Pixel rate is 10.41 GPixel/s versus 6.600 GPixel/s, texture rate is 52.04 GTexel/s versus 19.80 GTexel/s, and FP32 is 1.665 TFLOPS versus 633.6 GFLOPS. The Vega 10 Mobile adds FP16 at 3.331 TFLOPS with a 2:1 ratio, which the HD 8750M lacks entirely.

Memory size is 1024 MB dedicated DDR3 for the HD 8750M versus system shared for the Vega 10 Mobile. Bus width is 128 bit for the HD 8750M versus system shared for the Vega 10 Mobile.

The Vega 10 Mobile's predecessor is GCN 3.0 IGP and its successor is Navi II IGP, while the HD 8750M's predecessor is London and its successor is Gem System.

Head-to-Head Benchmarks

The only recorded head-to-head test is Geekbench OpenCL, and the result is unambiguous. The AMD Radeon Vega 10 Mobile scores 6476 against the AMD Radeon HD 8750M's 5970, a delta of 8.5 percent. This is a moderate but clear margin, not a blowout. The Vega 10 Mobile's nearest rivals in the database include the NVIDIA Quadro M5000M at 6481 (0.1 percent behind), the NVIDIA GeForce GT 555M at 6493 (0.3 percent behind), and the NVIDIA GeForce GTX 670M at 6513 (0.6 percent behind). The Vega 10 Mobile also edges out the NVIDIA RTX PRO 5000 72 GB Blackwell at 6407, a 1.1 percent advantage. Those close deltas show that the Vega 10 Mobile lands in a tight performance cluster, with its 6476 score sitting just a few points below several older NVIDIA mobile parts.

The HD 8750M's nearest rivals paint a similar picture of a tightly packed field. Its 5970 score is 0.2 percent below the NVIDIA Quadro K4000 at 5982, 0.2 percent above the NVIDIA Quadro K620M at 5957, 0.3 percent above the AMD Radeon HD 8730M at 5955, and 0.3 percent below the NVIDIA Quadro K4000M at 5986. The HD 8750M is essentially level with its immediate competitors, all within a 0.3 percent band. The 8.5 percent gap between the two review subjects is therefore much larger than the typical spread within each part's rival cluster.

The biggest win for the Vega 10 Mobile is the FP32 throughput comparison. At 1.665 TFLOPS, it delivers 2.6 times the HD 8750M's 633.6 GFLOPS. Texture rate shows an even larger gap in raw terms: 52.04 GTexel/s versus 19.80 GTexel/s, a 2.6x advantage. Pixel rate is 10.41 GPixel/s versus 6.600 GPixel/s, a 1.6x advantage. The shading unit and TMU counts both favor the Vega 10 Mobile by 66.7 percent. The HD 8750M's only recorded advantages are in memory configuration, where its dedicated 1024 MB DDR3 with 28.80 GB/s bandwidth provides fixed performance, and in base clock, where 775 MHz exceeds the Vega 10 Mobile's 300 MHz. The Vega 10 Mobile's boost clock of 1301 MHz, however, is 57.7 percent higher than the HD 8750M's 825 MHz boost.

The OpenCL score difference of 8.5 percent is smaller than the raw compute differences might suggest. The Vega 10 Mobile has 2.6x the FP32 throughput, yet scores only 8.5 percent higher in OpenCL. This suggests that the HD 8750M's dedicated memory bandwidth and lower latency help it close some of the gap in real-world compute workloads, or that the OpenCL test is not purely compute bound. The system dependent memory of the Vega 10 Mobile could also be a limiting factor, as its bandwidth varies with the host platform.

The Verdict

The data supports a clear but narrow recommendation. The AMD Radeon Vega 10 Mobile is the better performer in the only recorded benchmark, scoring 8.5 percent higher than the AMD Radeon HD 8750M in Geekbench OpenCL. It also holds a higher overall percentile rank at 37 versus 34, and its raw compute specifications are dramatically stronger: 2.6x FP32 throughput, 2.6x texture rate, and 1.6x pixel rate. For any OpenCL compute workload, the Vega 10 Mobile is the choice.

The HD 8750M's case rests on its dedicated memory subsystem. With 1024 MB of DDR3 on a 128 bit bus delivering 28.80 GB/s, it offers predictable, fixed bandwidth that does not depend on the host system. The Vega 10 Mobile's system shared memory means its performance is system dependent, so on a laptop with slower RAM, the gap could shrink or even reverse. The HD 8750M also has a higher base clock at 775 MHz versus 300 MHz, though its boost clock of 825 MHz is far below the Vega 10 Mobile's 1301 MHz.

Architecturally, the Vega 10 Mobile is the newer and more capable part. GCN 5.0 on 14 nm with 4,940 million transistors is a generation ahead of GCN 1.0 on 28 nm with 950 million transistors. It supports DirectX 12 feature level 12_1 versus 11_1, Vulkan 1.3 versus 1.2.170, and adds FP16 compute. The 10 W TDP also makes it suitable for thin and light systems with no power connectors. The HD 8750M, from 2013, is a legacy discrete part with no recorded TDP.

The verdict is that the Vega 10 Mobile is the stronger GPU for compute tasks and modern API support, while the HD 8750M offers dedicated memory that may help in memory sensitive workloads. The 8.5 percent OpenCL lead is modest, but it is backed by a much larger lead in raw throughput. Users choosing between these two should prefer the Vega 10 Mobile unless the HD 8750M's fixed memory bandwidth is a specific requirement. The data does not show any benchmark where the HD 8750M wins, so the Vega 10 Mobile is the safer pick.
