Intel HD Graphics P530 vs NVIDIA Quadro K2100M Comparison

The NVIDIA Quadro K2100M and Intel HD Graphics P530 represent two very different philosophies in mobile graphics: a dedicated professional GPU from 2013 versus an integrated graphics solution from 2015. The benchmark data shows a surprisingly close contest, with each card claiming one victory in the two shared tests, while their architectural approaches diverge sharply. The Quadro K2100M edges ahead in OpenCL compute, while the Intel part counters with a notable Vulkan advantage, leaving the overall picture dependent on workload.

Head-to-Head Benchmarks

The only two tests where both GPUs have recorded scores are Geekbench’s OpenCL and Vulkan compute workloads. In the OpenCL test, the NVIDIA Quadro K2100M scores 4587, narrowly beating the Intel HD Graphics P530’s 4549. That is a delta of just 0.8% in NVIDIA’s favor, a margin so thin it sits within run-to-run noise. The data suggests that for general-purpose compute through OpenCL, these two are effectively peers, despite the Quadro having a dedicated 2 GB of GDDR5 memory and the Intel using system-shared memory. The K2100M’s 576 shading units and 48.13 GB/s of bandwidth do not translate into a decisive compute advantage here.

The Vulkan test flips the result. Intel’s HD Graphics P530 posts 4571, which is 5% higher than the Quadro K2100M’s 4343. This is a more substantial gap, indicating that Intel’s Generation 9.0 architecture handles Vulkan’s modern API features noticeably better. The Quadro’s Vulkan support is listed as version 1.2.175, while the Intel part supports Vulkan 1.3, which likely explains part of the delta. The 5% advantage in Vulkan is the largest performance difference in either direction across the entire comparison, making it the single most important data point for anyone prioritizing that API.

Looking at the average benchmark scores, the Intel part actually leads overall. The HD Graphics P530 averages 4560 across its two tested workloads, while the Quadro K2100M averages 4151 across its three. However, this comparison is skewed because the Quadro’s average includes a Geekbench Metal score of 3524, a test the Intel part does not have. Removing that Metal result, the Quadro’s OpenCL and Vulkan scores average 4465, which is still slightly below the Intel’s 4560. The percentile rankings agree: Intel sits at the 26th percentile of all GPUs, one point above NVIDIA’s 25th percentile. This is a remarkably close contest, with the integrated solution holding a marginal edge in the aggregate.

Where Each One Wins

The NVIDIA Quadro K2100M wins in raw OpenCL compute by 0.8%, but that is a statistical tie. The more meaningful Intel victory is in Vulkan, where it leads by 5%. This suggests the Intel HD Graphics P530 is the better choice for applications that leverage Vulkan’s low-level overhead and explicit multi-threading, such as modern game engines or compute shaders written for that API. The Intel part’s support for Vulkan 1.3, compared to NVIDIA’s 1.2.175, aligns with this finding.

The Quadro K2100M, conversely, has a dedicated memory pool. While the benchmark scores do not show a clear advantage from that 2 GB GDDR5 with its 48.13 GB/s bandwidth, the architecture implies that workloads requiring consistent memory bandwidth without competing with the CPU for system RAM would favor the NVIDIA card. The Intel part’s bandwidth is listed as “System Dependent,” meaning its performance can vary based on the host platform’s memory configuration. The Quadro’s fixed 48.13 GB/s is a predictable quantity, whereas the Intel’s performance is a variable.

For power-constrained environments, the Intel HD Graphics P530 is the clear winner on paper. Its 15 W TDP is less than a third of the Quadro’s 55 W. That 40 W difference could be critical in a slim laptop chassis, even if the benchmark scores are comparable. The Quadro’s MXM Module slot width and lack of power connectors indicate it is designed for larger, workstation-class laptops, while the Intel part’s IGP form factor is meant for mainstream ultrabooks.

Specification Differences

The two GPUs differ in nearly every fundamental specification. The NVIDIA Quadro K2100M is built on a 28 nm process at TSMC, with 2,540 million transistors on a 221 mm² die. The Intel HD Graphics P530 uses Intel’s 14 nm+ process, with a die size of 123 mm² and no publicly listed transistor count. The process node advantage goes to Intel, being two generations smaller, which contributes to its lower power draw.

Clock speeds tell a story of their own. The Quadro runs at a fixed 667 MHz for both base and boost, with memory at 752 MHz (3 Gbps effective). The Intel part has a base clock of 350 MHz, but boosts to 1000 MHz, nearly tripling its base frequency. This dynamic clocking allows the Intel GPU to idle at very low power and ramp up when needed.

Memory is a fundamental divergence. The Quadro has 2 GB of GDDR5 on a 128-bit bus, yielding 48.13 GB/s of bandwidth. The Intel part uses system-shared memory, with no dedicated VRAM, and its bandwidth is listed as “System Dependent.” This means the Intel’s performance is tied to the host system’s RAM speed and configuration, while the Quadro has a fixed, dedicated pool.

The shading resources are heavily in NVIDIA’s favor. The Quadro packs 576 shading units, 48 texture mapping units, and 16 ROPs. The Intel part has only 192 shading units, 16 TMUs, and 3 ROPs. Yet despite having three times the shading units, the Quadro only manages a 0.8% OpenCL win, suggesting architectural efficiency differences are significant.

Architecture Differences

The NVIDIA Quadro K2100M is based on the Kepler architecture, specifically the GK106S chip. It is part of the Quadro Kepler-M generation (Kx100M), released in July 2013. Kepler was designed for compute and professional workloads, with a strong focus on FP32 performance. The Quadro delivers 768.4 GFLOPS of FP32 compute and 32.02 GTexel/s of texture fill rate.

The Intel HD Graphics P530 uses the Generation 9.0 architecture, built on the Skylake GT2 chip. It belongs to the HD Graphics-W (Skylake) generation, released in August 2015. This architecture is more modern, supporting DirectX 12 at feature level 12_1 and Vulkan 1.3, both higher than the Quadro’s DirectX 12 (11_0) and Vulkan 1.2.175. The Intel part also supports FP16 at 768.0 GFLOPS with a 2:1 ratio, which the Quadro does not list.

The memory architecture is the most consequential difference. The Quadro has dedicated GDDR5, which guarantees consistent bandwidth for graphics and compute tasks. The Intel part shares system memory, which can be a bottleneck or an advantage depending on the platform. The Quadro’s 48.13 GB/s is fixed; the Intel’s is variable, potentially exceeding or falling short of that figure based on the host system.

Power and form factor reflect their intended uses. The Quadro is a 55 W MXM Module, designed for upgradeable workstation laptops. The Intel part is a 15 W IGP, integrated directly into the processor and using the Ring Bus interface. The Quadro has no power connectors, while the Intel part has none listed, but the 40 W TDP difference shows the NVIDIA solution requires substantially more cooling.

The production status for both is end-of-life, but their release dates are two years apart. The Quadro’s predecessor is the Quadro Fermi-M and its successor is the Quadro Maxwell-M, while the Intel part has no listed predecessor or successor. This suggests the Intel HD Graphics P530 was a specific variant in the Skylake lineup, not a generational flagship.

The Verdict

The benchmark data presents a nuanced picture. If Vulkan compute is the primary workload, the Intel HD Graphics P530 is the clear choice, with a 5% lead over the Quadro K2100M. This is the largest performance delta in the entire comparison, and it aligns with Intel’s more modern API support. For OpenCL, the two are effectively tied, with NVIDIA holding a 0.8% edge that is unlikely to be perceptible.

The Intel part also wins on power efficiency by a wide margin, with a 15 W TDP versus 55 W. For any mobile application where battery life matters, the Intel solution is the obvious pick. Its system-shared memory is a potential drawback, but in the tested workloads, it did not hold the Intel part back.

The Quadro K2100M’s case rests on its dedicated 2 GB of GDDR5 memory and its 576 shading units. While the benchmarks do not show these translating into a decisive win, they provide a fixed, predictable memory bandwidth that is immune to system-level interference. For professional applications that rely on consistent memory performance, the Quadro’s 48.13 GB/s is a known quantity, whereas the Intel’s bandwidth is a variable.

The average benchmark scores favor Intel, with 4560 versus 4151, but that gap narrows to about 2% when the Metal test is excluded. The percentile rankings are nearly identical, at 26 for Intel and 25 for NVIDIA. This is not a contest of dominance; it is a split decision. Most users would be better served by the Intel HD Graphics P530, given its modern API support and dramatically lower power draw. The Quadro K2100M remains relevant only for niche workloads that require dedicated memory or legacy Kepler-era compute optimizations.
