GPU Comparison

The NVIDIA GRID K2 and Intel UHD Graphics 750 represent two entirely different approaches to graphics processing, and the benchmark data reflects that divide. The GRID K2 is a dedicated, data-center-oriented accelerator from 2013, while the UHD 750 is a modern integrated graphics solution built into Intel's Rocket Lake processors. In the single head-to-head benchmark available, the GRID K2 dominates, but the UHD 750 counters with superior API support and dramatically lower power consumption. This analysis breaks down the numbers to determine which GPU is the right choice for specific workloads.

Head-to-Head Benchmarks

The only direct comparison available is the Geekbench OpenCL test, and the result is a decisive victory for the NVIDIA GRID K2. It scores 10,602 points, while the Intel UHD Graphics 750 manages 6,743 points. This represents a 57.2% advantage for the NVIDIA part, a massive gap that underscores the fundamental performance difference between a dedicated discrete GPU and an integrated solution.

This OpenCL score is particularly telling because OpenCL is a compute-oriented API that stresses raw parallel processing capability. The GRID K2's 1,536 shading units and 128 texture mapping units allow it to crush the UHD 750's 256 shading units and 16 TMUs in this workload. The 57.2% delta is not a marginal difference; it is a generation-defining performance chasm that affects any GPU-accelerated compute task.

When looking at broader benchmark context, the GRID K2's average benchmark score across all tests is 8,080, placing it at the 42nd percentile of all GPUs. The UHD 750's average score is 7,441, which sits at the 40th percentile. While the GRID K2 is ahead in both the direct comparison and the overall average, the percentile difference is narrow, just 2 points, indicating that in the wider GPU landscape, both parts are positioned similarly for general-purpose tasks.

The GRID K2's Geekbench Metal score of 5,557 is not matched by the Intel part, which lacks Metal support entirely. This is a significant factor for any macOS or Metal-based workflow. Conversely, the UHD 750 posts a Geekbench Vulkan score of 8,138, a test that the GRID K2 cannot run due to its older Vulkan implementation. While the GRID K2 supports Vulkan 1.2.175, the UHD 750 supports Vulkan 1.4, and the benchmark data shows the Intel part is capable of strong Vulkan performance when the API is available.

Architecture Differences

The architectural divide between these two GPUs is stark. The NVIDIA GRID K2 is built on the Kepler architecture, using the GK104 chip manufactured on a 28 nm process at TSMC. This chip packs 3,540 million transistors into a 294 mm² die, yielding a transistor density of 12.0M per mm². The Intel UHD Graphics 750 uses the Generation 12.1 architecture with the Rocket Lake chip, built on Intel's 14 nm+++ process. Intel does not disclose transistor count or die size for this integrated part, but the process node is significantly older and less dense than what NVIDIA used in 2013.

Memory configuration further separates these products. The GRID K2 features 4 GB of dedicated GDDR5 memory on a 256-bit bus, delivering 160.0 GB/s of bandwidth. The UHD 750 uses System Shared memory, meaning it draws from the system's main RAM, with bandwidth described as "System Dependent." This is a critical weakness for the Intel part, shared memory introduces latency and bandwidth bottlenecks that a dedicated VRAM solution avoids.

The compute resources are massively lopsided. The GRID K2 has 1,536 shading units, 128 TMUs, and 32 ROPs. The UHD 750 has 256 shading units, 16 TMUs, and just 8 ROPs. These numbers translate directly to pixel and texture rates: the GRID K2 achieves 23.84 GPixel/s and 95.36 GTexel/s, while the UHD 750 manages only 10.40 GPixel/s and 20.80 GTexel/s. Floating-point performance tells the same story, the GRID K2 delivers 2.289 TFLOPS of FP32 compute, versus 665.6 GFLOPS for the Intel part. The UHD 750 does have an FP16 capability of 1,331.2 GFLOPS (2:1), a feature the GRID K2 lacks, but this does not compensate for the raw FP32 deficit.

Power and physical specifications could not be more different. The GRID K2 is a dual-slot card with a 225 W TDP, requiring a 550 W power supply and a 1x 6-pin plus 1x 8-pin power connector. It measures 267 mm (10.5 inches) in length. The UHD 750 is an IGP (integrated graphics processor) with a 15 W TDP, no power connectors, and no physical dimensions, it lives inside the CPU. The GRID K2 has no display outputs, while the UHD 750's display outputs are motherboard dependent.

API support shows a generational advantage for Intel. The UHD 750 supports DirectX 12 (12_1), while the GRID K2 only supports DirectX 12 (11_0). Both support OpenGL 4.6, but the UHD 750 has Vulkan 1.4 versus the GRID K2's Vulkan 1.2.175. The GRID K2 does support Metal (as evidenced by its benchmark score), which the Intel part does not.

The Verdict

The data is unambiguous: the NVIDIA GRID K2 is the superior performer for raw compute and graphics workloads. Its 57.2% lead in OpenCL, combined with a 2.289 TFLOPS FP32 rate versus 665.6 GFLOPS, makes it the clear choice for any GPU-accelerated compute task, server-side rendering, or virtual desktop infrastructure. The GRID K2's 4 GB of dedicated GDDR5 memory with 160.0 GB/s bandwidth is a massive advantage over system-shared memory, and its 42nd percentile ranking versus the UHD 750's 40th percentile confirms its edge in the broader GPU hierarchy.

However, the UHD 750 is not without merit. Its 15 W TDP is a fraction of the GRID K2's 225 W, making it the only viable option for power-constrained or fanless systems. It supports newer APIs, DirectX 12_1, Vulkan 1.4, and its Vulkan benchmark score of 8,138 shows it can perform respectably when the workload is optimized for modern APIs. The UHD 750 also has display outputs (motherboard dependent), while the GRID K2 has none.

The verdict depends entirely on the use case. For a server or workstation that needs maximum compute throughput and has the power budget and physical space, the GRID K2 wins outright. For a mainstream desktop or laptop that needs basic graphics acceleration with minimal power draw, the UHD 750 is the logical pick. The GRID K2's launch MSRP was 5,199 USD, reflecting its enterprise positioning, while the UHD 750 has no standalone price as it is integrated into a processor.

Where Each One Wins

The NVIDIA GRID K2 wins decisively in compute-heavy environments. Its 57.2% OpenCL advantage makes it ideal for scientific computing, machine learning inference, or any workload that leverages OpenCL for parallel processing. The 160.0 GB/s memory bandwidth ensures that large datasets remain accessible, and the 2.289 TFLOPS FP32 rate handles dense matrix operations. The lack of display outputs is a non-issue for server racks or virtualized environments where the GPU is accessed remotely.

The Intel UHD Graphics 750 wins in power-sensitive and modern-API scenarios. Its 15 W TDP is suitable for thin-and-light laptops or compact desktops where heat and power are at a premium. The Vulkan 1.4 support and DirectX 12_1 compliance mean it can run modern graphics applications with up-to-date features, even if the raw performance is lower. The motherboard-dependent display outputs make it a practical solution for everyday computing, video playback, and light productivity tasks.

The GRID K2's 42nd percentile ranking versus the UHD 750's 40th percentile shows that neither part is a top-tier performer, but the GRID K2's dedicated memory and compute resources give it a clear edge in any task that scales with parallel throughput. The UHD 750's strength lies in its integration, it is always present in a Rocket Lake system, requiring no additional hardware beyond the CPU itself.
