Intel UHD Graphics 750 vs NVIDIA GeForce GTX 880M Comparison

The NVIDIA GeForce GTX 880M and Intel UHD Graphics 750 represent two distinct approaches to graphics processing: a dedicated mobile discrete GPU from the Kepler era versus a modern integrated graphics solution. The benchmark data shows a clear, if narrow, overall advantage for one side, but the nature of that advantage is more nuanced than the final score suggests. The GTX 880M holds an average benchmark score of 8040, placing it in the 42nd percentile of all GPUs, while the UHD Graphics 750 achieves an average of 7441, placing it in the 40th percentile. The sole direct head-to-head comparison available, Geekbench OpenCL, reveals a 16.6% victory for the Intel part, a significant margin that flips the expected hierarchy based on the average scores.

Head-to-Head Benchmarks

The only direct benchmark comparison between the two GPUs in the data set is the Geekbench OpenCL test. Here, the Intel UHD Graphics 750 scores 6743, while the NVIDIA GeForce GTX 880M scores 5622. This results in a decisive 16.6% lead for the Intel integrated solution. This is a notable outcome, as it suggests that in a compute-heavy, general-purpose workload, the modern Intel architecture, despite its lower power envelope and integrated nature, is able to outperform the older dedicated NVIDIA chip. The data indicates the GTX 880M is effectively 16.6% slower than the UHD Graphics 750 in this specific test.

The overall benchmark averages, however, tell a slightly different story. The GTX 880M's average score of 8040 is derived from its performance in both Geekbench Metal and Geekbench OpenCL. Its Metal score is a strong 10458, which is significantly higher than its OpenCL score of 5622. This suggests the Kepler architecture has a particular strength in Apple's Metal API. The Intel UHD Graphics 750, on the other hand, has an average score of 7441, which is pulled up by a strong Geekbench Vulkan score of 8138 and its OpenCL score of 6743. The data suggests that the GTX 880M’s higher average is largely due to its exceptional Metal performance, a workload where the Intel part has no corresponding data point.

When looking at their respective peer groups, the two GPUs are competitive with different sets of hardware. The GTX 880M's average score of 8040 places it virtually on par with the NVIDIA Quadro P5000, which scores 8039 (0% delta), and the NVIDIA GeForce GTX 650 Ti, which scores 8053 (-0.2% delta). This indicates that the GTX 880M's overall compute capability is in the same class as these professional and older desktop parts. Conversely, the Intel UHD Graphics 750's average of 7441 places it in direct competition with the AMD Radeon HD 8850M (7447, -0.1% delta) and the AMD Radeon R7 350 (7425, 0.2% delta). The data shows a clear performance stratification: the GTX 880M's average is about 8% higher than the Intel part's average, but the Intel part wins the one test where they directly compete.

Architecture Differences

The most fundamental difference lies in their manufacturing processes and physical design. The NVIDIA GeForce GTX 880M is built on a 28 nm process at TSMC, featuring a large GK104 chip with 3,540 million transistors on a 294 mm² die, resulting in a transistor density of 12.0M / mm². In contrast, the Intel UHD Graphics 750 is an integrated graphics processor (IGP) built on Intel's 14 nm+++ process, using the Rocket Lake chip. The Intel part's transistor count and die size are not specified, but its "System Shared" memory configuration and Ring Bus interface confirm its integrated nature, sharing system resources rather than having dedicated VRAM.

The core configurations are starkly different. The GTX 880M is a high-end discrete part with 1536 shading units, 128 texture mapping units (TMUs), and 32 render output units (ROPs). The Intel UHD Graphics 750 is a modest integrated solution with 256 shading units, 16 TMUs, and 8 ROPs. This 6x difference in shading units and 8x difference in TMUs explains the GTX 880M's massive theoretical throughput advantages in raw pixel and texture rates. The GTX 880M achieves a pixel rate of 31.78 GPixel/s and a texture rate of 127.1 GTexel/s, while the Intel part manages 10.40 GPixel/s and 20.80 GTexel/s, respectively.

Memory architecture is a primary differentiator. The GTX 880M uses 8 GB of dedicated GDDR5 memory on a 256-bit bus, providing a bandwidth of 160.0 GB/s. The Intel UHD Graphics 750 uses "System Shared" memory, meaning its bandwidth is "System Dependent" and its bus width is "System Shared". This reliance on system memory is a significant bottleneck compared to the dedicated, high-speed GDDR5 of the NVIDIA part. Clock speeds also differ, with the GTX 880M running at a base of 954 MHz and a boost of 993 MHz, while the Intel part runs at a base of 300 MHz and a boost of 1300 MHz. The higher boost clock of the Intel part helps it in some compute tasks, but it cannot compensate for the massive difference in parallel execution resources.

Feature support and API compatibility also differ. The GTX 880M supports DirectX 12 (11_0), OpenGL 4.6, and Vulkan 1.2.175. The Intel UHD Graphics 750 supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4. The Intel part's support for DirectX 12_1 and a newer Vulkan version indicates a more modern feature set. In terms of compute, the GTX 880M's FP32 performance is 3.050 TFLOPS, while the Intel part is rated at 665.6 GFLOPS FP32 and 1,331.2 GFLOPS FP16 (2:1). The power draw is another clear differentiator, with the GTX 880M having a TDP of 122 W compared to just 15 W for the Intel IGP. The GTX 880M is an end-of-life MXM module, while the Intel UHD Graphics 750 is an end-of-life IGP. The GTX 880M was released in March 2014, while the Intel part came much later in March 2021.

The Verdict

The data presents a split decision that depends heavily on the workload. For raw compute tasks as measured by Geekbench OpenCL, the Intel UHD Graphics 750 is the clear winner, outperforming the GTX 880M by 16.6%. Its newer architecture and higher boost clock of 1300 MHz give it an edge in this specific synthetic test. The Intel part also demonstrates significant capability in Vulkan, scoring 8138, which confirms its modern feature set.

However, for overall average performance and peak throughput, the NVIDIA GeForce GTX 880M holds the advantage. Its average score of 8040 is higher than the Intel's 7441, and its Geekbench Metal score of 10458 is exceptionally strong. The GTX 880M's massive advantage in shading units, TMUs, and dedicated memory bandwidth (160.0 GB/s vs. System Dependent) gives it a clear edge in traditional graphics workloads. Its texture rate of 127.1 GTexel/s and pixel rate of 31.78 GPixel/s are vastly superior to the Intel part's 20.80 GTexel/s and 10.40 GPixel/s.

The choice between these two is therefore clear: the GTX 880M is the superior choice for any application that can leverage its dedicated memory and massive parallel processing power, particularly in graphics-intensive scenarios. The Intel UHD Graphics 750 is the better option for compute-focused tasks where its modern architecture and higher boost clock can be fully utilized, and where its dramatically lower TDP of 15 W is a critical factor. The data shows a trade-off between raw graphics power and modern compute efficiency. The GTX 880M wins on overall average score and graphics throughput, while the Intel part wins the direct compute comparison.
