AMD Radeon HD 8690M vs Intel UHD Graphics P750 Comparison

Intel UHD Graphics P750 and AMD Radeon HD 8690M are both end-of-life mobile graphics solutions, but they represent fundamentally different design philosophies. The Intel part is an integrated GPU (IGP) built into the Rocket Lake processor, while the AMD part is a discrete mobile GPU based on the GCN 1.0 architecture. Benchmark data from Geekbench OpenCL shows the Intel UHD Graphics P750 scoring 6554, which places it in the 38th percentile of all GPUs. The AMD Radeon HD 8690M scores 6137, placing it in the 36th percentile. The head-to-head comparison shows Intel winning by 6.8%, a meaningful margin in this performance class.

Where Each One Wins

The Intel UHD Graphics P750 wins the only benchmark category recorded: Geekbench OpenCL. Its score of 6554 outperforms the AMD Radeon HD 8690M's 6137 by 6.8%. This is not a marginal victory; it represents a clear computational throughput advantage for the Intel part. The Intel GPU's nearest rivals in the database include the AMD Radeon HD 7730M (avg score 6581, delta -0.4%), the AMD Radeon R7 M460 (avg score 6612, delta -0.9%), the NVIDIA GeForce GTX 670M (avg score 6513, delta 0.6%), and the NVIDIA GeForce GT 555M (avg score 6493, delta 0.9%). This cluster of scores shows the Intel UHD Graphics P750 sitting right in the middle of a tight pack of older discrete mobile GPUs, indicating that its integrated design delivers performance on par with dedicated parts from several generations ago.

The AMD Radeon HD 8690M, despite losing the head-to-head, still has its own competitive positioning. Its score of 6137 places it near the NVIDIA RTX A400 (avg score 6078, delta 1%), the NVIDIA GeForce MX230 (avg score 6077, delta 1%), the Intel Iris Pro Graphics 6200 (avg score 6117, delta 0.3%), and the AMD Radeon HD 6950 (avg score 6210, delta -1.2%). This suggests the AMD part is competitive with low-end discrete GPUs and high-end integrated graphics of its era. However, in every recorded benchmark, the Intel UHD Graphics P750 comes out ahead. The wins tally is 1 for Intel and 0 for AMD, meaning there is no single test category where the AMD Radeon HD 8690M demonstrates superiority in this dataset.

The Verdict

The data is unambiguous: the Intel UHD Graphics P750 is the faster GPU. It wins the Geekbench OpenCL test by 6.8%, and its percentile ranking (38th) is two points higher than the AMD Radeon HD 8690M's (36th). For users who prioritize raw compute performance in OpenCL workloads, the Intel part is the clear choice. The AMD Radeon HD 8690M does have advantages in other areas—it is a discrete GPU with dedicated GDDR5 memory—but those hardware features do not translate into a benchmark win in this dataset. If the choice is strictly between these two based on performance, the Intel UHD Graphics P750 should be selected.

However, the context matters. The Intel UHD Graphics P750 is an integrated part with a 15 W TDP, meaning it draws power from the CPU package. The AMD Radeon HD 8690M is a discrete GPU with its own memory interface (PCIe 3.0 x8) and 2 GB of GDDR5 memory on a 64-bit bus, delivering 32.00 GB/s of bandwidth. For systems where a discrete GPU is required for compatibility or upgradeability, the AMD part still offers a functional solution, but its performance is lower. The verdict from the benchmarks is that the Intel UHD Graphics P750 provides superior compute performance, and the AMD Radeon HD 8690M is the slower option in this comparison.

Head-to-Head Benchmarks

The only recorded benchmark is Geekbench OpenCL, and it shows a decisive Intel victory. The Intel UHD Graphics P750 scores 6554, while the AMD Radeon HD 8690M scores 6137. The delta is 6.8% in favor of Intel. To put this in perspective, the Intel part's nearest rival, the AMD Radeon HD 7730M, scores 6581, which is only 0.4% higher than Intel's result. The AMD Radeon HD 8690M's nearest rival, the Intel Iris Pro Graphics 6200, scores 6117, which is 0.3% lower than AMD's result. This means the Intel UHD Graphics P750 is performing at the level of a mid-range discrete mobile GPU from the AMD HD 7700 series, while the AMD Radeon HD 8690M is performing closer to high-end integrated graphics from Intel's Iris Pro line.

The raw specifications help explain the score difference. The Intel UHD Graphics P750 has 256 shading units, 64 texture mapping units (TMUs), and 32 render output units (ROPs). Its peak FP32 performance is 665.6 GFLOPS, and its texture rate is 83.20 GTexel/s. The AMD Radeon HD 8690M has 320 shading units, but only 20 TMUs and 8 ROPs. Its peak FP32 performance is 624.0 GFLOPS, and its texture rate is 19.50 GTexel/s. Despite having more shading units, the AMD part's lower TMU and ROP counts likely contribute to its reduced OpenCL score. The Intel part also has a higher pixel rate (41.60 GPixel/s vs 7.800 GPixel/s) and a much higher texture rate, which are critical for graphics workloads.

The clock speeds tell a different story. The AMD Radeon HD 8690M runs at a base clock of 925 MHz and a boost clock of 975 MHz, while the Intel UHD Graphics P750 has a base clock of 350 MHz and a boost clock of 1300 MHz. The AMD part's higher base clock does not compensate for its lower TMU and ROP counts, and the Intel part's boost clock of 1300 MHz is significantly higher than AMD's 975 MHz boost. Memory bandwidth is also a factor: the AMD part has 32.00 GB/s of dedicated GDDR5 bandwidth, while the Intel part uses system shared memory with bandwidth that is system dependent. Despite the dedicated memory advantage for AMD, the Intel part still wins the compute benchmark.

Architecture Differences

The Intel UHD Graphics P750 is based on Intel's Generation 12.1 architecture, built on the Rocket Lake chip. It uses a 14 nm+++ process node from Intel's own foundry. The AMD Radeon HD 8690M, in contrast, is based on GCN 1.0 architecture, using the "Sun" chip, and is fabricated on TSMC's 28 nm process. The AMD part has 690 million transistors on a 56 mm² die, with a transistor density of 12.3M per mm². The Intel part does not have transistor or die size data recorded in the fact pack.

The memory subsystems differ significantly. The Intel UHD Graphics P750 uses system shared memory, with a system dependent bandwidth, and its memory type and bus width are also system shared. The AMD Radeon HD 8690M has dedicated 2 GB of GDDR5 memory on a 64-bit bus, delivering a fixed 32.00 GB/s of bandwidth. The AMD part's memory clock is 1000 MHz (4 Gbps effective). This dedicated memory is a hardware advantage for AMD, but it does not translate to a compute win in the recorded benchmark.

The compute unit configurations are also distinct. The Intel UHD Graphics P750 has 256 shading units, 64 TMUs, and 32 ROPs, with a pixel rate of 41.60 GPixel/s and a texture rate of 83.20 GTexel/s. Its FP32 performance is 665.6 GFLOPS, and its FP16 performance is 1,331.2 GFLOPS (2:1 ratio). The AMD Radeon HD 8690M has 320 shading units, 20 TMUs, and 8 ROPs, with a pixel rate of 7.800 GPixel/s and a texture rate of 19.50 GTexel/s. Its FP32 performance is 624.0 GFLOPS, and no FP16 performance is recorded. The Intel part's higher TMU and ROP counts are likely the primary reason for its higher texture and pixel rates, which contribute to its superior OpenCL score.

The bus interfaces differ: the Intel UHD Graphics P750 uses a Ring Bus interface, while the AMD Radeon HD 8690M uses PCIe 3.0 x8. The Intel part is an IGP with a 15 W TDP, while the AMD part does not have a recorded TDP. The AMD part's release date is 2013-02-28, and its predecessor and successor are listed as "London" and "Gem System," respectively. The Intel part has no release date, predecessor, or successor data. In terms of API support, both support DirectX 12, but the Intel part supports 12 (12_1) while the AMD part supports 12 (11_1). Both support OpenGL 4.6, but the Intel part supports Vulkan 1.4 while the AMD part supports Vulkan 1.2.170. Display outputs for the Intel part are motherboard dependent, while the AMD part has no display output data.
