Intel UHD Graphics 710 vs NVIDIA GeForce GT 645M Comparison

Head-to-Head Benchmarks

The recorded data shows a split decision between the NVIDIA GeForce GT 645M and the Intel UHD Graphics 710, with each claiming one benchmark victory. In Geekbench OpenCL, the Intel UHD Graphics 710 posts a score of 3496 against the NVIDIA's 2680, a margin of 23.3 percent in Intel's favor. That is a substantial gap, placing the integrated solution firmly ahead in compute-oriented workloads that leverage OpenCL acceleration.

The Geekbench Vulkan test flips the outcome. Here, the NVIDIA GeForce GT 645M scores 4875, while the Intel UHD Graphics 710 manages 4088. That gives NVIDIA a 19.3 percent advantage, a clear win for the older discrete GPU in Vulkan-based rendering tasks. The delta between the two tests is telling: Intel's architecture handles OpenCL efficiently, but NVIDIA's Kepler-based chip retains an edge in modern graphics API workloads.

Looking at the broader database averages, the NVIDIA GeForce GT 645M holds an average benchmark score of 4411 across all recorded tests, while the Intel UHD Graphics 710 averages 3792. That puts NVIDIA roughly 16.3 percent ahead on aggregate performance. The percentile rankings reinforce this: the GT 645M sits at the 26th percentile among all GPUs, whereas the UHD 710 lands at the 22nd percentile. Neither part is a powerhouse, but the data consistently places NVIDIA's mobile discrete GPU above Intel's entry-level integrated graphics in overall output.

The nearest rivals for each part provide additional context. The GT 645M's closest competitor, the NVIDIA GeForce 930M, averages 4388, a mere 0.5 percent behind. The Intel Iris Pro Graphics 5200 trails by 1.2 percent at 4360, and even the NVIDIA GeForce RTX 4070 GDDR6, an outlier in this comparison, sits at 4335, 1.8 percent behind. On the other side, the AMD Radeon R7 M260 leads the GT 645M by 1.9 percent with a score of 4499. For the Intel UHD Graphics 710, the NVIDIA GeForce GTX 650 averages 3823, which is 0.8 percent ahead, while the NVIDIA GeForce MX110 sits 1.1 percent ahead at 3834. The GT 635M trails by 1.4 percent at 3740, and the Quadro 3000M is 2 percent behind at 3718.

Where Each One Wins

The Intel UHD Graphics 710 wins decisively in OpenCL compute workloads. Its score of 3496 represents a 23.3 percent advantage over the GT 645M's 2680. This suggests that for applications that rely heavily on OpenCL, such as certain productivity tools, video encoding utilities, or physics simulations, Intel's integrated solution delivers more raw throughput. The architecture's ability to sustain higher boost clocks, up to 1300 MHz, likely contributes to this performance, though the database does not break down clock scaling per workload.

The NVIDIA GeForce GT 645M wins in Vulkan graphics performance. Its 4875 score against Intel's 4088, a 19.3 percent lead, indicates that gaming or graphics-intensive applications using Vulkan will run smoother on the NVIDIA part. This is notable because Vulkan is a modern API, and the GT 645M, despite being nearly a decade older, still outperforms Intel's newer integrated graphics in this specific test. The discrete GPU's dedicated memory subsystem, with 2 GB of DDR3 on a 128-bit bus, likely provides an advantage in memory bandwidth-sensitive rendering tasks.

For users prioritizing compute tasks like OpenCL-accelerated filters or data processing, the Intel UHD Graphics 710 is the better choice. For those running Vulkan-based games or graphics applications, the NVIDIA GeForce GT 645M holds the edge. The aggregate benchmark average, however, favors NVIDIA overall, making it the more balanced performer across both tests.

Architecture Differences

The NVIDIA GeForce GT 645M uses the GK107 chip, built on the Kepler architecture, manufactured by TSMC on a 28 nm process. It packs 1,270 million transistors into a die size of 118 mm², yielding a transistor density of 10.8 million transistors per square millimeter. The Intel UHD Graphics 710, by contrast, uses the Alder Lake chip, based on Generation 12.2 architecture, fabricated by Intel on a 10 nm process. The database lists no transistor count or die size for Intel's part, so direct density comparisons are not possible.

The core configurations differ sharply. NVIDIA's GPU features 384 shading units, 32 texture mapping units, and 16 raster output units. Intel's integrated graphics is far leaner, with 128 shading units, 8 TMUs, and 8 ROPs. This explains why NVIDIA's raw fill rates are higher in some respects: the GT 645M achieves a pixel rate of 6.240 GPixel/s and a texture rate of 24.96 GTexel/s, while the UHD 710 posts 10.40 GPixel/s and 10.40 GTexel/s. Interestingly, Intel's pixel rate is higher, but its texture rate is less than half of NVIDIA's, reflecting the difference in TMU count.

Clock behavior also diverges. The GT 645M runs at a base clock of 709 MHz with a boost up to 780 MHz. The UHD 710 starts at 300 MHz and boosts to 1300 MHz. Intel's higher boost clock partially compensates for fewer cores, but the FP32 throughput tells the story: NVIDIA delivers 599.0 GFLOPS, while Intel manages 332.8 GFLOPS. Intel does offer FP16 support at 665.6 GFLOPS with a 2:1 ratio, a capability NVIDIA's Kepler chip lacks entirely.

Memory architecture is fundamentally different. The GT 645M uses dedicated 2 GB of DDR3 with a 128-bit bus and 28.80 GB/s bandwidth. The UHD 710 relies on system shared memory, with the bus width and bandwidth marked as system dependent. This means Intel's performance can vary based on the host system's RAM configuration, whereas NVIDIA has fixed, dedicated resources.

Specification Differences

The two GPUs differ across nearly every specification field. The process node is 28 nm for NVIDIA versus 10 nm for Intel. NVIDIA's chip has 384 shading units against Intel's 128, 32 TMUs versus 8, and 16 ROPs versus 8. The base clock is 709 MHz for NVIDIA and 300 MHz for Intel, while boost clocks are 780 MHz and 1300 MHz respectively. Memory size is 2 GB for NVIDIA, with type DDR3 and a 128-bit bus, while Intel uses system shared memory throughout. Bandwidth is 28.80 GB/s for NVIDIA versus system dependent for Intel.

Pixel rate favors Intel at 10.40 GPixel/s versus NVIDIA's 6.240 GPixel/s, but texture rate strongly favors NVIDIA at 24.96 GTexel/s versus 10.40 GTexel/s. FP32 performance is 599.0 GFLOPS for NVIDIA and 332.8 GFLOPS for Intel. Intel additionally supports FP16 at 665.6 GFLOPS, which NVIDIA does not list. Power consumption differs, with NVIDIA rated at 32 W and Intel at 15 W, though both are classified as IGP slot width with no power connectors.

The bus interface is PCIe 3.0 x16 for NVIDIA versus Ring Bus for Intel. Display outputs are portable device dependent for NVIDIA and motherboard dependent for Intel. API support shows Intel ahead on DirectX, supporting version 12 (12_1) against NVIDIA's 12 (11_0). Both support OpenGL 4.6, but Vulkan support differs: NVIDIA lists 1.2.175, while Intel lists 1.4. Release dates are far apart, with the GT 645M launching in 2012 and the UHD 710 in 2022. NVIDIA's production status is end-of-life, as is Intel's.
