Intel UHD Graphics P750 vs NVIDIA GeForce GTX 770M Comparison

The benchmark data presents a clear, albeit narrow, comparison between the Intel UHD Graphics P750 and the NVIDIA GeForce GTX 770M. While both are end-of-life products, their performance profiles and architectural designs diverge significantly, leading to distinct use cases. This analysis relies solely on the provided facts to dissect their head-to-head results, architectural blueprints, and overall standings in the GPU landscape.

Head-to-Head Benchmarks

The single direct comparison available is the Geekbench OpenCL test. In this metric, the NVIDIA GeForce GTX 770M delivers a score of 8,552, while the Intel UHD Graphics P750 achieves 6,554. This represents a decisive victory for the NVIDIA solution, which outperforms the Intel integrated graphics by 23.4%. This is a substantial margin, indicating that in raw compute workloads leveraging OpenCL, the discrete GPU holds a significant advantage.

To contextualize this win, examining the rivals for each card is instructive. The GTX 770M’s OpenCL score of 8,552 is not its average; its average benchmark score across all tests is 6,000. This average places it in the 35th percentile of all GPUs, with its nearest rivals including the AMD Radeon RX 6400 (average score 6,001) and the NVIDIA RTX PRO 6000 Blackwell Server (average score 5,996). The delta percentages against these rivals are effectively zero (0% and 0.1%, respectively), showing that its average performance is a baseline in its performance tier. The Intel P750, conversely, has an average benchmark score of 6,554, placing it in the 38th percentile. Its nearest rivals are the AMD Radeon HD 7730M (average 6,581, delta -0.4%) and the NVIDIA GeForce GTX 670M (average 6,513, delta 0.6%). This indicates the Intel part's average score is competitive with those older discrete mobile GPUs, sitting marginally above the GTX 670M and slightly below the Radeon HD 7730M.

The head-to-head data, however, shows the GTX 770M's OpenCL score is significantly higher than its own average, suggesting it performs particularly well in this specific workload. The Intel P750's OpenCL score is essentially equal to its average (6,554 vs. 6,554), meaning its performance is consistent. The 23.4% delta in this single test is the most critical numerical takeaway, as it represents the only direct comparison and heavily influences the overall win count, which stands at zero for the Intel P750 and one for the GTX 770M.

The Verdict

From a pure performance standpoint based on the provided data, the NVIDIA GeForce GTX 770M is the clear winner in the only available head-to-head benchmark. Its 23.4% lead in Geekbench OpenCL is a decisive margin that cannot be ignored. Users requiring the highest possible compute performance in applications that utilize OpenCL should favor the GTX 770M without hesitation.

However, the verdict is not a universal endorsement. The Intel UHD Graphics P750, being an integrated processor graphics solution with a 15 W TDP, offers a fundamentally different value proposition. Its 6,554 average benchmark score is competitive with the GTX 770M's 6,000 average, even though its peak performance is lower. The data suggests that for general, sustained workloads, the Intel part's average performance is respectable and falls within a similar performance band as the GTX 770M's overall average. The GTX 770M's advantage is its peak compute capability, while the Intel P750 offers a more consistent baseline.

The choice depends on the specific workload. If the priority is maximum throughput in a single, demanding compute task, the GTX 770M is the superior option. If the priority is a balanced, power-efficient solution for a system where discrete graphics are not feasible, the Intel P750's performance, while lower, is not categorically inadequate when compared to the GTX 770M's average. The data shows a trade-off: the GTX 770M for peak performance, the Intel P750 for its integrated nature and efficiency.

Architecture Differences

The two GPUs are built on fundamentally different architectures and manufacturing processes. The Intel UHD Graphics P750 is based on Intel's Generation 12.1 architecture, fabricated on a 14 nm+++ process at Intel's own foundry. It is part of the HD Graphics-W (Rocket Lake) generation. In contrast, the NVIDIA GeForce GTX 770M uses the Kepler architecture, built on a 28 nm process by TSMC, and belongs to the GeForce 700M generation.

The core configurations highlight their different design philosophies. The Intel P750 has 256 shading units, 64 texture mapping units (TMUs), and 32 render output units (ROPs). Its pixel rate is 41.60 GPixel/s, and its texture rate is 83.20 GTexel/s. The NVIDIA GTX 770M, on the other hand, has 960 shading units, 80 TMUs, and only 24 ROPs. Its pixel rate is lower at 15.94 GPixel/s, and its texture rate is 63.76 GTexel/s. This is a notable divergence: the Intel part has more ROPs, leading to a higher pixel fill rate, while the NVIDIA part has far more shading units and a higher texture fill rate.

Memory subsystems are completely different. The Intel P750 uses System Shared memory, meaning its size, type, and bus width are all dependent on the host system, and its bandwidth is "System Dependent." The GTX 770M has a dedicated 3 GB of GDDR5 memory on a 192-bit bus, providing a fixed bandwidth of 96.19 GB/s. This dedicated memory is a significant advantage for the NVIDIA part, as it does not compete with the CPU for bandwidth.

Clock speeds also differ. The Intel P750 has a base clock of 350 MHz and a boost clock of 1300 MHz. The GTX 770M has a base clock of 706 MHz and a boost clock of 797 MHz. Despite the Intel part's higher boost clock, its lower shading unit count results in a significantly lower FP32 performance of 665.6 GFLOPS compared to the GTX 770M's 1.530 TFLOPS. The Intel P750 supports FP16 at 1,331.2 GFLOPS (2:1), while the GTX 770M has no listed FP16 performance. The Intel chip also has a much lower TDP of 15 W versus the GTX 770M's 75 W.

Where Each One Wins

The NVIDIA GeForce GTX 770M wins decisively in the sole head-to-head benchmark, the Geekbench OpenCL test, with a 23.4% lead. This indicates it is the superior choice for applications that leverage OpenCL for compute-intensive tasks. Its dedicated 3 GB of GDDR5 memory with 96.19 GB/s bandwidth also provides a clear advantage in scenarios where memory bandwidth is a bottleneck, as it does not rely on system memory. Its higher FP32 performance of 1.530 TFLOPS further suggests it can handle more complex floating-point calculations per second.

The Intel UHD Graphics P750 wins in the context of its own average performance. Its average benchmark score of 6,554 is higher than the GTX 770M's average of 6,000, suggesting it may offer more consistent performance across a wider range of unspecified workloads. Its architecture also has a higher pixel rate (41.60 GPixel/s vs. 15.94 GPixel/s), which could translate to an advantage in specific rasterization tasks. Finally, its drastically lower TDP of 15 W versus 75 W makes it the clear winner in terms of power efficiency, a critical factor for systems where thermal and power budgets are constrained.
