Architecture Differences

The NVIDIA GeForce GTX 650 Ti is built on the Kepler architecture using the GK106S chip, manufactured by TSMC on a 28 nm process. The die contains 2,540 million transistors across 221 mm², yielding a transistor density of 11.5M per mm². In contrast, the Intel UHD Graphics P750 uses the Generation 12.1 architecture on the Rocket Lake chip, fabricated by Intel on a 14 nm+++ process. The database does not list transistor count or die size for the Intel part, so a direct density comparison is not possible from recorded data.

The GTX 650 Ti is a discrete, single-slot card with a 145 mm (5.7 inches) length, a PCIe 3.0 x16 bus interface, and display outputs of 2x DVI and 1x mini-HDMI 1.4a. The UHD Graphics P750 is an integrated graphics processor (IGP) with a Ring Bus interface and motherboard-dependent display outputs, meaning its physical integration is entirely different from the discrete NVIDIA board.

Compute resources differ substantially. The GTX 650 Ti has 768 shading units, 64 texture mapping units, and 16 ROPs. The UHD Graphics P750 has 256 shading units, 64 TMUs, and 32 ROPs. Although the Intel part has fewer shading units, it doubles the ROP count. The clock behavior also differs: the GTX 650 Ti lists a memory clock of 1350 MHz (5.4 Gbps effective) with no base or boost clock recorded, while the Intel part has a base clock of 350 MHz and a boost clock of 1300 MHz.

Feature support follows the architectures. The GTX 650 Ti supports DirectX 12 (11_0), OpenGL 4.6, and Vulkan 1.2.175. The UHD Graphics P750 supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4. The Intel part also records FP16 performance of 1,331.2 GFLOPS (2:1), while the GTX 650 Ti has no FP16 figure in the database. Both are end-of-life products, but the GTX 650 Ti has a release date of October 2012 and a successor in the GeForce 700 series, while the Intel part has no release date, predecessor, or successor listed.

Head-to-Head Benchmarks

The only direct benchmark comparison in the database is Geekbench OpenCL, where the NVIDIA GeForce GTX 650 Ti scores 7877 against 6554 for the Intel UHD Graphics P750. That is a 20.2% advantage for the NVIDIA card, and it represents the sole recorded head-to-head win for either product. The GTX 650 Ti takes the win count 1 to 0.

A 20.2% lead in OpenCL is significant, but the context matters. The GTX 650 Ti is a discrete GPU with dedicated GDDR5 memory and 86.40 GB/s of bandwidth, while the Intel part relies on system shared memory with bandwidth dependent on the host platform. The recorded pixel rate tells a different story: the Intel UHD Graphics P750 achieves 41.60 GPixel/s versus 14.85 GPixel/s for the GTX 650 Ti, a 2.8x advantage in fill rate terms. Similarly, the Intel part reaches 83.20 GTexel/s versus 59.39 GTexel/s for the NVIDIA card. These rates are not directly measured in the head-to-head test, but the database lists them as architectural specifications.

The FP32 compute figures also favor the NVIDIA part: 1,425.4 GFLOPS versus 665.6 GFLOPS, a 2.1x difference. The Intel part counters with FP16 capability at 1,331.2 GFLOPS (2:1), which the GTX 650 Ti does not list. The average benchmark scores reflect the OpenCL result: 8053 for the GTX 650 Ti and 6554 for the Intel part, a difference of 1499 points or roughly 22.9% based on the averages.

Nearest rival data places each GPU in a distinct performance tier. The GTX 650 Ti's closest competitors, the GRID K2 at 8080 and GTX 650 Ti Boost at 8067, are all within 0.3% of its 8053 average. The UHD Graphics P750's nearest rivals, led by the Radeon R7 M460 at 6612, are within 0.9% of its 6554 average. The gap between the two GPUs is therefore larger than the gap between either GPU and its own closest rivals, indicating a clear tier separation.

Specification Differences

The two GPUs differ across nearly every recorded specification. Process node: the GTX 650 Ti uses 28 nm from TSMC, while the UHD Graphics P750 uses 14 nm+++ from Intel. Transistors and die size: 2,540 million transistors on 221 mm² for the NVIDIA part, no data for the Intel part. Memory: 1024 MB GDDR5 on a 128-bit bus with 86.40 GB/s bandwidth versus System Shared memory with System Dependent bandwidth.

Clock speeds: the GTX 650 Ti records only a memory clock of 1350 MHz (5.4 Gbps effective), while the Intel part lists base 350 MHz and boost 1300 MHz. Shading units: 768 versus 256. TMUs: 64 for both. ROPs: 16 versus 32. Pixel rate: 14.85 GPixel/s versus 41.60 GPixel/s. Texture rate: 59.39 GTexel/s versus 83.20 GTexel/s. FP32: 1,425.4 GFLOPS versus 665.6 GFLOPS. FP16: not listed versus 1,331.2 GFLOPS (2:1).

TDP: 110 W versus 15 W. Slot width: Single-slot versus IGP. Power connectors: 1x 6-pin versus none. Suggested PSU: 300 W versus not listed. Bus interface: PCIe 3.0 x16 versus Ring Bus. Display outputs: 2x DVI and 1x mini-HDMI 1.4a versus motherboard dependent. DirectX: 12 (11_0) versus 12 (12_1). Vulkan: 1.2.175 versus 1.4. Release date: October 2012 versus not listed. Launch MSRP: 149 USD for the GTX 650 Ti, none for the Intel part.

The Verdict

The benchmark data gives a clear overall winner: the NVIDIA GeForce GTX 650 Ti. It wins the only head-to-head test by 20.2%, has a higher average benchmark score (8053 versus 6554), and sits at a higher percentile rank (42 versus 38). Its nearest rivals cluster around 8040 to 8080, while the Intel part's rivals cluster around 6493 to 6612, so the GTX 650 Ti competes in a faster performance class by the database's own measurements.

The Intel UHD Graphics P750 is not without arguments in its favor. It has a dramatically lower TDP at 15 W versus 110 W, doubling the ROP count (32 versus 16), a higher pixel rate (41.60 versus 14.85 GPixel/s), a higher texture rate (83.20 versus 59.39 GTexel/s), and support for DirectX 12 (12_1) and Vulkan 1.4. For an integrated part, these are meaningful capabilities, but they do not translate into a higher OpenCL score.

The verdict from the data is that the GTX 650 Ti is the stronger GPU for compute workloads as measured by Geekbench OpenCL, while the UHD Graphics P750 offers superior fill rates and newer API support at a fraction of the power draw. A user prioritizing raw benchmark scores should choose the NVIDIA card; a user prioritizing integration efficiency and newer feature levels should consider the Intel part.

Where Each One Wins

The NVIDIA GeForce GTX 650 Ti wins in the only recorded benchmark, Geekbench OpenCL, by 20.2% (7877 versus 6554). It also leads in average benchmark score, FP32 compute (1,425.4 GFLOPS versus 665.6 GFLOPS), shading units (768 versus 256), and dedicated memory bandwidth (86.40 GB/s versus system shared). The database shows it as the better choice for compute-heavy tasks that rely on OpenCL, given that its nearest rivals all score between 8039 and 8080.

The Intel UHD Graphics P750 wins in several specification-level categories. It leads in pixel rate (41.60 GPixel/s versus 14.85 GPixel/s), texture rate (83.20 GTexel/s versus 59.39 GTexel/s), ROPs (32 versus 32 being a 2x advantage), TDP efficiency (15 W versus 110 W), and API versions (DirectX 12 (12_1) and Vulkan 1.4). Its nearest rivals score between 6493 and 6612 in the database's nearest rival table, placing it in a lower performance tier overall, but its fill rates suggest it handles resolution-heavy workloads better than its OpenCL score implies.
