Intel UHD Graphics 750 vs NVIDIA GeForce GTX 650 Ti Boost Comparison

The NVIDIA GeForce GTX 650 Ti Boost and the Intel UHD Graphics 750 occupy opposite ends of the graphics spectrum, yet benchmark data places them surprisingly close in overall standing. The GTX 650 Ti Boost holds a 42nd percentile rank across all GPUs, while the Intel integrated solution sits at the 40th percentile. In direct head-to-head testing, the NVIDIA card wins both available benchmarks, but the margins tell a more nuanced story than the raw victory count suggests. The data indicates the GTX 650 Ti Boost is the clear choice for anyone needing discrete performance, while the UHD 750 serves a fundamentally different purpose as an integrated solution where the GPU is merely a secondary feature of the CPU package.

The Verdict

The benchmark results point to a straightforward conclusion: the NVIDIA GeForce GTX 650 Ti Boost outperforms the Intel UHD Graphics 750 in every measured category. In Geekbench OpenCL, the NVIDIA card scores 9302 against Intel's 6743, a 38% advantage. In Geekbench Vulkan, the gap narrows to 23.4%, with scores of 10041 and 8138 respectively. These are not marginal differences — the GTX 650 Ti Boost delivers substantially higher compute throughput in both API environments.

However, the verdict is not merely about performance. The GTX 650 Ti Boost is a dual-slot, 134 W discrete card requiring a 300 W power supply and a 6-pin power connector. The UHD 750 is an integrated graphics processor (IGP) with a 15 W TDP, drawing from system memory and requiring no additional power hardware. For users building a compact or low-power system where discrete graphics are impractical, the UHD 750 is the only viable option between these two. For anyone with a standard desktop chassis and a power supply meeting the 300 W recommendation, the GTX 650 Ti Boost offers decisively better performance. The data does not support any scenario where the Intel part wins on raw capability.

Where Each One Wins

The GTX 650 Ti Boost wins both head-to-head benchmarks, making its case straightforward: it is faster in OpenCL and Vulkan workloads. The OpenCL result shows the NVIDIA card delivering 9302 points, which places it within 0.2% of the GeForce GTX 650 Ti (8053) and 0.3% of the GeForce GTX 880M (8040) among its nearest rivals. This suggests the GTX 650 Ti Boost sits comfortably in the mid-range discrete GPU tier, competitive with other Kepler-based solutions.

The UHD 750, despite losing both comparisons, demonstrates respectable integrated performance. Its OpenCL score of 6743 places it within 0.1% of the AMD Radeon HD 8850M (7447) and 0.2% of the AMD Radeon R7 350 (7425). Notably, it trails the NVIDIA GeForce GTX 1650 by only 0.4% in average score, though that comparison comes from the nearestRivals field rather than direct head-to-head testing. The Vulkan score of 8138 shows the Intel architecture handles modern graphics APIs reasonably well for an IGP, but it still falls 23.4% short of the NVIDIA card.

Where the UHD 750 wins is in system integration and power efficiency. Its 15 W TDP is a fraction of the GTX 650 Ti Boost's 134 W. It uses system-shared memory rather than dedicated GDDR5, eliminating the need for a separate memory bus. The UHD 750 requires no slot width, no power connectors, and no suggested PSU rating. These advantages are qualitative rather than benchmark-driven, but they are decisive for certain use cases like small form factor builds or office systems.

Architecture Differences

The two GPUs come from entirely different design philosophies. The GTX 650 Ti Boost uses NVIDIA's Kepler architecture, built on a 28 nm process at TSMC. The chip, designated GK106, contains 2,540 million transistors on a 221 mm² die, yielding a transistor density of 11.5M per mm². This is a dedicated graphics processor with its own memory subsystem: 2 GB of GDDR5 on a 192-bit bus, delivering 144.2 GB/s of bandwidth.

The UHD 750 is Intel's Generation 12.1 architecture, fabricated on Intel's 14 nm+++ process. It is part of the Rocket Lake generation of HD Graphics. The chip has 256 shading units, 16 texture mapping units, and 8 raster output units — significantly fewer than the NVIDIA card's 768 shading units, 64 TMUs, and 24 ROPs. The Intel part relies on system-shared memory, with bandwidth described as "System Dependent," meaning performance scales with the host system's memory configuration.

Clock behavior differs markedly. The GTX 650 Ti Boost runs at a base of 980 MHz with a boost of 1032 MHz, while its memory operates at 1502 MHz (6 Gbps effective). The UHD 750 has a base clock of 300 MHz and boosts to 1300 MHz. Despite the higher boost clock, the Intel part's reduced execution resources limit its throughput. The pixel rate tells the story: 16.51 GPixel/s for NVIDIA versus 10.40 GPixel/s for Intel. Texture rate is even more lopsided at 66.05 GTexel/s versus 20.80 GTexel/s.

API support reveals generational differences. The GTX 650 Ti Boost supports DirectX 12 (11_0), OpenGL 4.6, and Vulkan 1.2.175. The UHD 750 supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4. The Intel part has a more recent DirectX feature level and newer Vulkan version, reflecting its later release date, but this does not translate into benchmark superiority.

Head-to-Head Benchmarks

The Geekbench OpenCL test delivers the largest margin between these two GPUs. The GTX 650 Ti Boost scores 9302, while the UHD 750 manages 6743. That is a 38% delta in favor of NVIDIA. This result makes sense given the architectural disparity: the NVIDIA card has 768 shading units, 64 TMUs, and 24 ROPs against Intel's 256 shading units, 16 TMUs, and 8 ROPs. The NVIDIA card also has dedicated GDDR5 memory with 144.2 GB/s bandwidth, whereas the Intel part shares system memory with bandwidth that is system dependent. For compute workloads that scale with shading unit count and memory bandwidth, the GTX 650 Ti Boost is in a different league.

The Geekbench Vulkan test shows a tighter contest, though NVIDIA still wins decisively. The GTX 650 Ti Boost scores 10041, and the UHD 750 scores 8138, a 23.4% delta. The Intel part's Vulkan 1.4 support is newer than NVIDIA's Vulkan 1.2.175, which may help close the gap slightly. Still, the NVIDIA card's advantage in raw throughput — 1.585 TFLOPS FP32 versus 665.6 GFLOPS — is overwhelming. The UHD 750 does offer FP16 performance of 1,331.2 GFLOPS (2:1), which suggests some compute scenarios could favor it if they leverage half-precision, but no FP16 benchmark appears in the head-to-head data.

Looking at the nearest rivals reinforces the positioning. The GTX 650 Ti Boost's average score of 8067 places it in a tight cluster with the GRID K2 (8080), GTX 650 Ti (8053), GTX 880M (8040), and Quadro P5000 (8039). All are within 0.3% of each other, indicating the Kepler architecture delivers consistent mid-range performance. The UHD 750's average of 7441 places it near the HD 8850M (7447) and R7 350 (7425), with the GTX 1650 (7472) slightly ahead. The Intel integrated solution holds its own against older discrete mobile GPUs but cannot match dedicated desktop parts from any generation.

Specification Differences

The two GPUs differ across nearly every specification field. The GTX 650 Ti Boost uses a 28 nm TSMC process, while the UHD 750 uses Intel's 14 nm+++. Transistor count and die size are only listed for the NVIDIA part: 2,540 million transistors on a 221 mm² die with 11.5M transistors per mm². The Intel part lists no transistor data.

Memory configurations are fundamentally different. The NVIDIA card has 2 GB of GDDR5 on a 192-bit bus with 144.2 GB/s bandwidth. The Intel part uses system-shared memory with system-shared type and bus width, and bandwidth described as system dependent.

Execution resources favor NVIDIA heavily: 768 shading units versus 256, 64 TMUs versus 16, and 24 ROPs versus 8. Clock speeds see the Intel part boost higher at 1300 MHz versus 1032 MHz, but the base clocks are 980 MHz for NVIDIA and 300 MHz for Intel. The NVIDIA card has a memory clock of 1502 MHz (6 Gbps effective), while the Intel part has no dedicated memory clock.

Power and physical requirements diverge completely. The GTX 650 Ti Boost has a 134 W TDP, occupies a dual-slot form factor, requires a 1x 6-pin power connector and a 300 W suggested PSU, and measures 241 mm (9.5 inches) in length. The UHD 750 has a 15 W TDP, is an IGP with no slot width, no power connectors, no PSU recommendation, and no listed dimensions.

Display outputs differ: the NVIDIA card provides 2x DVI, 1x HDMI 1.4a, and 1x DisplayPort 1.2, while the Intel part's outputs are motherboard dependent. Bus interfaces are PCIe 3.0 x16 for NVIDIA and Ring Bus for Intel. API support shows the Intel part with newer DirectX 12 (12_1) and Vulkan 1.4 versus NVIDIA's DirectX 12 (11_0) and Vulkan 1.2.175. OpenGL is identical at 4.6 for both. The GTX 650 Ti Boost launched with a 169 USD MSRP; the UHD 750 has no listed MSRP.
