AMD Radeon HD 8850M vs Intel UHD Graphics P750 Comparison

The Verdict

The benchmark data positions these two as distant neighbors in performance, not direct rivals. The AMD Radeon HD 8850M holds a decisive 13.6% lead over the Intel UHD Graphics P750 in the single recorded OpenCL test, scoring 7447 against 6554. That gap is substantial enough to make the AMD part the clear choice for any workload that leans on compute throughput, which is exactly what OpenCL measures. The Intel part, meanwhile, sits in the 38th percentile of all GPUs, while the AMD card reaches the 40th percentile, a narrow overall ranking difference that belies the larger gap in raw score.

Who should pick which? The data suggests the AMD Radeon HD 8850M for anyone prioritizing raw compute performance in legacy or embedded contexts, as it outperforms its Intel counterpart by a meaningful margin. The Intel UHD Graphics P750, however, carries a 15 W TDP and an IGP form factor, making it the sensible option for low-power, motherboard-integrated systems where the AMD card's discrete nature and higher performance are not required. The Intel part also supports newer API feature levels: DirectX 12 (12_1) versus DirectX 12 (11_1), and Vulkan 1.4 versus 1.2.170. For users who need the latest graphics API features or who are constrained by power and space, the Intel part wins. For users who need the extra compute headroom, the AMD card is the only choice in this pairing.

Architecture Differences

The two GPUs come from different design philosophies and process generations. The AMD Radeon HD 8850M is built on GCN 1.0 architecture, using the Venus chip, fabricated on a 28 nm process at TSMC. It packs 1,500 million transistors into a 123 mm² die, yielding a transistor density of 12.2 million per square millimeter. The Intel UHD Graphics P750, by contrast, uses the Rocket Lake chip with Intel's Generation 12.1 architecture, built on Intel's 14 nm+++ process, which represents an older and less dense node, though the database does not record its transistor count or die size.

The compute configurations differ sharply. The AMD part fields 640 shading units, 40 texture mapping units, and 16 ROPs. The Intel part has only 256 shading units but doubles the TMUs to 64 and the ROPs to 32. This inversion explains the fill-rate picture: the Intel UHD Graphics P750 posts a pixel rate of 41.60 GPixel/s and a texture rate of 83.20 GTexel/s, both far above the AMD card's 10.00 GPixel/s and 25.00 GTexel/s. Yet in raw floating-point throughput, the AMD card leads with 800.0 GFLOPS FP32 against Intel's 665.6 GFLOPS. The Intel part does offer FP16 support at 1,331.2 GFLOPS with a 2:1 ratio, a feature the AMD card lacks entirely, as no FP16 number is recorded.

Clock behavior also diverges. The AMD Radeon HD 8850M runs a 575 MHz base clock with a 625 MHz boost, while the Intel part starts at 350 MHz and boosts to 1300 MHz, a much wider range that reflects its integrated, power-managed nature. Memory configurations are fundamentally different: the AMD card uses 2 GB of GDDR5 on a 128-bit bus with 64.00 GB/s of bandwidth, while the Intel part uses system-shared memory with system-dependent bandwidth, which the database lists as "System Shared" for size, type, and bus width.

The bus interface also separates them: the AMD card connects via PCIe 3.0 x16, while the Intel part uses a Ring Bus, typical of an integrated GPU. Display outputs for the Intel part are motherboard-dependent, whereas the AMD card's outputs are not recorded. Both are end-of-life products. The AMD part is the successor to the London chip and the predecessor to the Gem System, while the Intel part has no recorded predecessor or successor. The AMD card was released on 2013-03-31, and no release date is recorded for the Intel part.

Head-to-Head Benchmarks

Only one head-to-head benchmark appears in the database: Geekbench OpenCL. In that test, the AMD Radeon HD 8850M scores 7447 against the Intel UHD Graphics P750's 6554, a delta of 13.6% in favor of AMD. This is the single largest recorded win in this comparison, and it aligns with the AMD card's higher FP32 throughput of 800.0 GFLOPS versus 665.6 GFLOPS, a difference of about 20%.

The rivals list for each GPU provides additional context. The AMD Radeon HD 8850M's nearest rival is the Intel UHD Graphics 750, which scores 7441, a delta of just 0.1%, making the two effectively identical in this benchmark. The AMD card also edges the AMD Radeon R7 350 (7425, delta 0.3%) and trails the NVIDIA GeForce GTX 1650 (7472, delta -0.3%) and the Intel Arc A310 (7550, delta -1.4%) by narrow margins. This places the AMD part in a tight cluster where 100 points separate the top from the bottom.

The Intel UHD Graphics P750's nearest rivals tell a different story. Its closest competitor is the AMD Radeon HD 7730M at 6581, a delta of -0.4%, meaning the Intel part scores slightly lower. It also trails the AMD Radeon R7 M460 (6612, delta -0.9%) and beats the NVIDIA GeForce GTX 670M (6513, delta 0.6%) and the NVIDIA GeForce GT 555M (6493, delta 0.9%). The Intel part's score of 6554 sits in a similarly tight cluster, but at a lower absolute level than the AMD card's group.

The data indicates that the AMD Radeon HD 8850M outperforms the Intel UHD Graphics P750 by a margin that is larger than the typical spread within each GPU's own rival group. The 13.6% delta is the only head-to-head number recorded, and it is unambiguous: AMD wins the compute benchmark decisively.

Where Each One Wins

The AMD Radeon HD 8850M wins on raw compute performance. Its 7447 OpenCL score beats the Intel part's 6554 by 13.6%, and its FP32 throughput of 800.0 GFLOPS exceeds the Intel part's 665.6 GFLOPS. This makes it the better option for any workload that stresses general-purpose compute, such as OpenCL-accelerated tasks, where the benchmark data shows a clear advantage. The AMD card also has a dedicated 2 GB GDDR5 memory pool with 64.00 GB/s of bandwidth, which gives it a fixed, predictable memory subsystem, unlike the Intel part's system-dependent shared memory.

The Intel UHD Graphics P750 wins on fill-rate and power efficiency. Its pixel rate of 41.60 GPixel/s and texture rate of 83.20 GTexel/s dwarf the AMD card's 10.00 GPixel/s and 25.00 GTexel/s, indicating that for workloads that are fill-rate bound, the Intel part is far stronger. Its 15 W TDP makes it a low-power integrated solution, whereas the AMD card's TDP is not recorded, but as a discrete part it is less likely to fit into the same power envelope. The Intel part also supports FP16 at 1,331.2 GFLOPS, which the AMD card does not, and it offers newer API versions, including DirectX 12 (12_1) and Vulkan 1.4, which matter for compatibility with modern software stacks.

In practical terms, the AMD Radeon HD 8850M is the pick for compute-heavy tasks where the 13.6% performance lead translates into real time savings. The Intel UHD Graphics P750 is the pick for integrated, low-power systems where fill rate and API modernity matter more than raw compute, and where the shared memory architecture is acceptable. The data shows two different strengths, and the correct choice depends entirely on whether the workload is compute-bound or fill-rate-bound.
