GPU Comparison

Intel UHD Graphics P630 and NVIDIA Quadro K3100M are both end-of-life mobile-class graphics solutions, but they target fundamentally different workloads. Benchmark data shows a 1-1 split in head-to-head tests, with the Quadro K3100M taking a decisive lead in OpenCL compute while the Intel P630 edges ahead in Vulkan performance. The average benchmark scores are nearly identical, 5370 for the Intel part versus 5154 for the NVIDIA, placing both in the 30th and 31st percentiles of all GPUs respectively, indicating they are entry-level performers by modern standards.

Where Each One Wins

The NVIDIA Quadro K3100M is the clear winner in raw compute throughput. Its Geekbench OpenCL score of 6154 crushes the Intel UHD Graphics P630's 5111, a 16.9% advantage. This gap reflects the Quadro's hardware design: 768 shading units, 64 texture mapping units, and 32 ROPs, paired with 4 GB of dedicated GDDR5 memory on a 256-bit bus delivering 102.4 GB/s of bandwidth. The FP32 performance of 1,084.4 GFLOPS is more than double the Intel's 460.8 GFLOPS. For any application that leverages OpenCL, be it rendering, scientific simulation, or video processing, the Quadro K3100M is the superior choice. Its nearest rival, the AMD Radeon R7 M260X, scores 5161 on average, showing the Quadro sits comfortably in its class.

The Intel UHD Graphics P630 wins the Vulkan matchup, scoring 5628 against the Quadro's 5484, a 2.6% margin. This is a narrower victory but notable because it comes from an integrated GPU with just 192 shading units and 24 TMUs. The Vulkan advantage suggests the Intel architecture's newer Generation 9.5 design handles modern low-level APIs more efficiently than the aging Kepler architecture. The P630's 15 W TDP also makes it the obvious choice for power-constrained systems, whereas the Quadro's 75 W TDP demands a dedicated cooling solution and larger power budget. The Intel part's "System Shared" memory model means it scales with system RAM, which can be an advantage in memory-flexible configurations but a disadvantage in bandwidth-sensitive tasks.

The Verdict

Pick the NVIDIA Quadro K3100M if your priority is compute performance in OpenCL-based workloads. The 16.9% lead in that benchmark is substantial, and the dedicated 4 GB GDDR5 frame buffer with 102.4 GB/s bandwidth offers predictable, high-throughput memory access that an integrated solution cannot match. The Quadro's 768 shading units and 32 ROPs deliver 11.30 GPixel/s pixel rate and 45.18 GTexel/s texture rate, making it the stronger choice for any GPU-accelerated task beyond casual use. It also supports Metal (score 3823), which the Intel part does not, expanding its compatibility with Apple's compute framework.

Pick the Intel UHD Graphics P630 if you need Vulkan performance in a power-efficient package. Its 2.6% Vulkan win, while modest, demonstrates that the integrated solution can hold its own in modern graphics APIs. The 15 W TDP is one-fifth of the Quadro's 75 W, making it ideal for thin-and-light laptops where battery life and thermal management are critical. The P630 also supports DirectX 12 (12_1) and Vulkan 1.3, while the Quadro is limited to DirectX 12 (11_0) and Vulkan 1.2.175. For general productivity, web browsing, and light gaming, the Intel part is more than adequate and far more practical in terms of system integration.

Head-to-Head Benchmarks

The Geekbench OpenCL test is the biggest differentiator. The Quadro K3100M scores 6154, while the Intel P630 scores 5111, giving the NVIDIA part a 16.9% advantage. This large delta is consistent with the hardware specifications: the Quadro has 4x the shading units (768 vs 192), 2.67x the TMUs (64 vs 24), and over 10x the ROPs (32 vs 3). The Quadro's FP32 throughput of 1,084.4 GFLOPS versus 460.8 GFLOPS means it can process more than twice as many floating-point operations per second. In practice, any OpenCL benchmark that scales with shader count and memory bandwidth will favor the Quadro overwhelmingly.

The Geekbench Vulkan test flips the script. The Intel P630 scores 5628, edging out the Quadro's 5484 by 2.6%. This result is surprising given the Quadro's superior raw specs, but it highlights architectural efficiency. The Intel Generation 9.5 architecture, built on a 14 nm+++ process, benefits from a modern design that handles Vulkan's explicit command structures better than NVIDIA's older Kepler architecture from 2013. The P630's 921.6 GFLOPS FP16 performance (2:1 ratio) also provides a compute advantage in scenarios that utilize half-precision operations, a feature the Quadro lacks entirely. This Vulkan win suggests that for gaming or applications built on Vulkan, the Intel part offers competitive performance despite its lower absolute compute power.
