Architecture Differences

The architectural gap between these two GPUs is vast. The Intel UHD Graphics P630 is an integrated graphics processor built on Intel's Generation 9.5 architecture, using the Comet Lake GT2 chip. It is fabricated on a 14 nm+++ process at Intel's foundry. The NVIDIA GeForce RTX 3080 12 GB represents a completely different class of hardware, using the Ampere architecture with the GA102 chip, manufactured by Samsung on an 8 nm process.

The transistor counts tell a dramatic story. The RTX 3080 12 GB packs 28,300 million transistors on a 628 mm² die, giving a transistor density of 45.1 million per square millimeter. The Intel P630 has no recorded transistor count or die size in the database, but its integrated nature and 15 W TDP suggest a far smaller footprint. The process node difference, 14 nm+++ versus 8 nm, also explains why NVIDIA can fit so many more transistors into a similar physical space.

Compute resources differ by an order of magnitude. The Intel P630 has 192 shading units, 24 texture mapping units, and only 3 raster output units. The RTX 3080 12 GB has 8960 shading units, 280 TMUs, and 96 ROPs. The RTX 3080 also includes 70 ray tracing cores and 280 tensor cores, features completely absent from the Intel integrated solution. These hardware differences translate into raw throughput numbers: the Intel P630 delivers 460.8 GFLOPS of FP32 performance, while the RTX 3080 12 GB delivers 30.64 TFLOPS, a 66-fold difference.

The memory subsystem is equally divergent. The Intel P630 relies on system shared memory with system dependent bandwidth, meaning its performance scales with the host system's RAM. The RTX 3080 12 GB has dedicated 12 GB of GDDR6X memory on a 384-bit bus, achieving 912.4 GB/s of bandwidth. This dedicated high-speed memory is critical for the RTX 3080's performance in memory-intensive workloads.

Both GPUs support DirectX 12, but at different feature levels. The Intel P630 supports DirectX 12 (12_1), while the RTX 3080 12 GB supports DirectX 12 Ultimate (12_2), which includes additional features like hardware ray tracing and mesh shaders. Vulkan support also differs slightly, with the Intel P630 at 1.3 and the RTX 3080 at 1.4.

Where Each One Wins

The Intel UHD Graphics P630 wins in the integrated graphics space. Its 15 W TDP makes it suitable for thin-and-light laptops where power efficiency matters more than raw performance. The system shared memory architecture means no dedicated VRAM is needed, reducing cost and complexity for basic computing tasks. The database shows it has a higher percentile ranking (31st) than the RTX 3080 12 GB (28th), suggesting it performs closer to its peer group.

The Intel P630 also wins on compatibility with legacy systems. Its Ring Bus interface and motherboard dependent display outputs indicate it is designed to work within a tightly integrated platform. For users who only need basic 2D acceleration, video playback, and light productivity, the Intel P630 is the appropriate choice.

The NVIDIA GeForce RTX 3080 12 GB wins decisively in raw performance across every measurable compute metric. Its FP32 throughput of 30.64 TFLOPS versus 460.8 GFLOPS is not a contest. The 70 ray tracing cores enable hardware accelerated ray tracing, a feature the Intel P630 lacks entirely. The 280 tensor cores provide AI acceleration capabilities that are simply unavailable on the Intel solution.

The RTX 3080 12 GB also wins in memory bandwidth, with 912.4 GB/s versus the system dependent bandwidth of the Intel P630. This makes it suitable for high-resolution gaming, 3D rendering, video editing, and machine learning workloads. The dedicated 12 GB GDDR6X memory allows large datasets and textures to reside on the GPU without competing with the CPU for system memory.

Specification Differences

The two GPUs differ in nearly every specification category. The process node shows Intel at 14 nm+++ versus Samsung's 8 nm for NVIDIA. The Intel P630 is an integrated GPU (IGP) with a 15 W TDP, while the RTX 3080 12 GB is a dual-slot discrete card with a 350 W TDP and requires a 750 W power supply, connecting via a single 12-pin power connector.

Clock speeds differ substantially. The Intel P630 has a base clock of 350 MHz and a boost clock of 1200 MHz. The RTX 3080 12 GB has a base clock of 1260 MHz and a boost clock of 1710 MHz, with memory clocked at 1188 MHz (19 Gbps effective). The Intel P630's memory clock is listed as "System Shared," indicating it uses the host system's memory timing.

Memory configuration shows the biggest gap. The Intel P630 has system shared memory with no dedicated size, type, or bus width. The RTX 3080 12 GB has 12 GB of GDDR6X on a 384-bit bus. The bus interface also differs: the Intel P630 uses Ring Bus, while the RTX 3080 12 GB uses PCIe 4.0 x16.

Physical specifications are only recorded for the RTX 3080 12 GB: 285 mm length (11.2 inches), 112 mm height (4.4 inches), and 40 mm width (1.6 inches). The Intel P630 has no recorded dimensions, as it is integrated onto the motherboard. Display outputs also differ, with the Intel P630 being motherboard dependent and the RTX 3080 12 GB offering 1x HDMI 2.1 and 3x DisplayPort 1.4a.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark comparisons between the Intel UHD Graphics P630 and the NVIDIA GeForce RTX 3080 12 GB. Instead, each GPU has its own benchmark results from different test suites, making direct score comparisons impossible.

The Intel UHD Graphics P630 has two recorded benchmark scores. In Geekbench OpenCL, it scores 5111. In Geekbench Vulkan, it scores 5628. These results give it an average benchmark score of 5370. Its nearest rival, the AMD Radeon R7 M445, scores 5358, which is 0.2% higher. The NVIDIA GeForce 840M scores 5322, which is 0.9% higher than the Intel P630.

The NVIDIA GeForce RTX 3080 12 GB has one recorded benchmark score: 4791 in 3DMark Steel Nomad DX12. This gives it an average benchmark score of 4791. Its nearest rival, the AMD Radeon R5 M255, scores 4788, which is 0.1% higher. The NVIDIA GeForce GTX 560M scores 4855, which is 1.3% higher than the RTX 3080 12 GB.

The percentile rankings are interesting. The Intel P630 ranks in the 31st percentile of all GPUs, while the RTX 3080 12 GB ranks in the 28th percentile. This means the integrated Intel GPU sits slightly higher in the overall distribution than the flagship-class NVIDIA GPU, despite the enormous gap in raw specifications. This likely reflects the different benchmark suites used and the populations of GPUs each is compared against.

The closest rival deltas for the Intel P630 range from -0.8% to 1%, indicating it performs very close to its immediate competitors. The RTX 3080 12 GB's closest rival deltas range from -1.3% to 0.8%, showing a similar tight clustering around its score. Neither GPU dramatically outperforms its nearest rivals in the database.

The Verdict

The data presents a clear picture, though not the one raw specifications might suggest. The Intel UHD Graphics P630 and NVIDIA GeForce RTX 3080 12 GB serve entirely different purposes, and the database reflects this through different benchmark suites and performance distributions.

For users of the Intel UHD Graphics P630, the data shows a capable integrated solution that performs within 1% of its nearest rivals, including the AMD Radeon R7 M445 and NVIDIA GeForce 840M. Its 31st percentile ranking indicates it sits in the lower-middle range of all GPUs. This GPU is appropriate for basic computing, office work, and light multimedia consumption where dedicated graphics are unnecessary.

The NVIDIA GeForce RTX 3080 12 GB, despite its massive hardware advantage, shows a lower percentile ranking at 28th. This is likely due to the specific benchmark used (3DMark Steel Nomad DX12) and the comparison pool. Its nearest rivals, including the AMD Radeon R5 M255 and NVIDIA GeForce 940MX, are all low-end mobile parts, which is unusual for a high-end desktop GPU. This suggests the recorded benchmark may not represent the RTX 3080 12 GB's typical performance class.

The verdict depends entirely on the user's needs. Those requiring integrated graphics for a low-power system should choose the Intel UHD Graphics P630. Those needing dedicated high-performance graphics with ray tracing, tensor cores, and 12 GB of GDDR6X memory should choose the NVIDIA GeForce RTX 3080 12 GB. The data cannot directly compare the two, as they were tested with different benchmarks, but the specification differences make the intended use cases clear. The RTX 3080 12 GB was launched with an MSRP of 799 USD, reflecting its position as a high-end discrete GPU.
