Intel UHD Graphics 750 vs NVIDIA GeForce GTX 650 Ti Comparison

The NVIDIA GeForce GTX 650 Ti and the Intel UHD Graphics 750 represent two fundamentally different approaches to graphics: a dedicated, end-of-life discrete card from 2012 versus an integrated processor graphics unit from 2021. The benchmark data from this database shows a clear, albeit narrow, overall victory for the older NVIDIA part, driven primarily by its substantial lead in OpenCL compute workloads, while the Intel solution demonstrates surprising competitiveness in Vulkan rendering.

Head-to-Head Benchmarks

The head-to-head comparison consists of two benchmark suites: Geekbench OpenCL and Geekbench Vulkan. In the OpenCL test, the NVIDIA GeForce GTX 650 Ti scores 7,877 points, while the Intel UHD Graphics 750 scores 6,743 points. This represents a 16.8% advantage for the NVIDIA card, which is a decisive margin in this synthetic compute benchmark. The OpenCL workload heavily favors the dedicated GPU’s higher raw throughput and dedicated memory bandwidth.

The Vulkan test tells a much closer story. The GTX 650 Ti scores 8,229 points, edging out the Intel UHD Graphics 750’s 8,138 points by a mere 1.1%. This 91-point difference is within the margin of noise for many benchmark runs, suggesting that in real-world Vulkan-based gaming or rendering scenarios, the two solutions would perform nearly identically. The Intel part’s modern architecture and driver optimizations for Vulkan clearly close the gap that exists in OpenCL.

Overall, the NVIDIA card wins both head-to-head tests, securing a 2-0 record in this comparison. However, the nature of the wins is telling: a dominant 16.8% victory in compute, followed by a marginal 1.1% win in graphics. The average benchmark score, calculated across both tests, puts the GTX 650 Ti at 8,053 points, compared to 7,441 for the Intel UHD 750, a 7.6% aggregate difference.

Where Each One Wins

The NVIDIA GeForce GTX 650 Ti is the clear winner in compute-heavy applications. Its 16.8% lead in OpenCL performance indicates that tasks utilizing general-purpose GPU computing—such as video encoding, physics simulations, or data processing—will run noticeably faster on this dedicated card. The 1,425.4 GFLOPS of FP32 compute power provides a substantial raw throughput advantage over the Intel part.

The Intel UHD Graphics 750, despite losing both benchmarks, wins in the context of Vulkan efficiency. Its 1.1% deficit against a dedicated GPU that draws over seven times more power is remarkable. The Intel part achieves this with 256 shading units running at a maximum boost clock of 1,300 MHz, compared to the GTX 650 Ti’s 768 shading units. This suggests that for Vulkan-based titles, the integrated graphics solution is surprisingly capable and may offer a smoother experience than its compute scores would suggest.

Where the Intel part genuinely wins is in the broader system context. It consumes only 15 W of power, operates as an IGP with no additional power connectors, and uses system shared memory, eliminating the need for a dedicated VRAM allocation. The GTX 650 Ti, by contrast, requires a 110 W TDP, a 1x 6-pin power connector, and a 300 W suggested power supply. For users building a low-power or compact system, the Intel solution is the only viable choice despite its benchmark deficit.

Architecture Differences

The architectural gap between these two GPUs spans nearly a decade of design philosophy. The NVIDIA GeForce GTX 650 Ti uses the GK106S chip built on TSMC’s 28 nm process, housing 2,540 million transistors on a 221 mm² die. This Kepler architecture was designed for dedicated graphics performance, featuring 768 shading units, 64 texture mapping units, and 16 raster output units. It accesses 1,024 MB of dedicated GDDR5 memory over a 128-bit bus, providing 86.40 GB/s of bandwidth.

The Intel UHD Graphics 750 uses the Rocket Lake chip built on Intel’s 14 nm+++ process. As part of the Generation 12.1 architecture, it packs 256 shading units, 16 TMUs, and 8 ROPs. Its memory interface is entirely system-shared, with bandwidth described as "System Dependent," meaning performance scales with the host system’s DDR4 memory configuration. The Intel part’s base clock is 300 MHz, boosting to 1,300 MHz.

Compute throughput differences are stark. The GTX 650 Ti delivers 1,425.4 GFLOPS of FP32 performance, more than double the Intel part’s 665.6 GFLOPS. However, the Intel UHD 750 does offer FP16 support at 1,331.2 GFLOPS with a 2:1 ratio, a feature absent from the NVIDIA data. Pixel and texture rates also favor NVIDIA: 14.85 GPixel/s versus 10.40 GPixel/s, and 59.39 GTexel/s versus 20.80 GTexel/s respectively.

API support shows a modern advantage for Intel. The UHD 750 supports DirectX 12 (12_1), a higher feature level than the GTX 650 Ti’s DirectX 12 (11_0). Both support OpenGL 4.6, but Intel supports Vulkan 1.4 compared to NVIDIA’s 1.2.175. The GTX 650 Ti offers 2x DVI and 1x mini-HDMI 1.4a outputs, while the Intel part’s display outputs are motherboard dependent.

The Verdict

Based strictly on the benchmark data, the NVIDIA GeForce GTX 650 Ti is the superior performer. It wins both head-to-head tests, holds a 16.8% advantage in OpenCL, and maintains a 1.1% edge in Vulkan. Its average benchmark score of 8,053 places it in the 42nd percentile of all GPUs, while the Intel UHD 750’s 7,441 average places it in the 40th percentile. The nearest rival data confirms the GTX 650 Ti is tightly clustered with other mid-range parts like the GTX 880M and Quadro P5000, while the UHD 750 sits near the Radeon HD 8850M and Radeon R7 350.

For users with an existing PCIe 3.0 x16 slot and a 300 W power supply, the GTX 650 Ti is the clear choice for any workload that benefits from dedicated compute or graphics performance. Its 16.8% OpenCL lead makes it particularly suitable for GPU-accelerated tasks. The card’s launch MSRP was 149 USD, though it is now end-of-life.

For users building a new system around a Rocket Lake processor, the Intel UHD Graphics 750 offers a compelling integrated solution. Its Vulkan score of 8,138 is only 1.1% behind the dedicated NVIDIA card, making it viable for Vulkan-based games at modest settings. The 15 W power draw and IGP form factor eliminate the need for a discrete card entirely. The decision ultimately hinges on whether the 16.8% OpenCL performance gap or the 110 W power requirement matters more for the specific use case.
