GPU Comparison

Head-to-Head Benchmarks

In the single recorded benchmark comparison, the GeForce GT 1010 and the Iris Pro Graphics P6300 are separated by a clear margin. The GeForce GT 1010 scores 6698 points in Geekbench OpenCL, while the Iris Pro Graphics P6300 scores 5712 points. This translates to a 17.3% advantage for the NVIDIA part, a substantial gap in raw compute performance.

The delta becomes more meaningful when placed against each card's competitive neighborhood. The GeForce GT 1010 sits at the 38th percentile of all GPUs in the database, with rivals clustered tightly around its score. The AMD Radeon R7 M370 scores 6764, only 1% ahead, while the AMD FirePro M5100 leads by 1.9% with 6830 points. On the other side, the AMD Radeon R7 M460 trails by 1.3% at 6612, and the AMD Radeon HD 7730M is 1.8% behind at 6581. The GT 1010 is essentially trading blows with a tight pack of mid-range mobile and entry desktop parts, and its win over the Iris Pro is larger than any of these inter-rival gaps.

The Iris Pro Graphics P6300, meanwhile, lands at the 33rd percentile overall. Its nearest rivals are also tightly grouped: the NVIDIA GeForce GTX 670MX scores 5721, just 0.1% ahead, the GeForce GTX 550 Ti scores 5731 (0.3% ahead), the AMD Radeon HD 8790M scores 5691 (0.4% behind), and the NVIDIA Quadro M500M scores 5604 (1.9% behind). The Iris Pro is therefore not an outlier in its class, but it is clearly anchored in a lower performance tier than the GT 1010. The 17.3% delta between the two cards is roughly ten times larger than the typical spread among their respective immediate rivals.

The single-benchmark nature of this matchup means the headline result is straightforward: the GeForce GT 1010 wins the only test recorded, and it does so decisively. However, the underlying specifications hint at why the gap is so pronounced. The GT 1010 operates with a 1228 MHz base clock and a 1468 MHz boost clock, while the Iris Pro runs at 300 MHz base and 800 MHz boost. Even accounting for the Iris Pro's larger execution resource pool, the clock disadvantage is severe. The GT 1010 also has dedicated GDDR5 memory with a 64-bit bus and 48.06 GB/s of bandwidth, whereas the Iris Pro relies on System Shared memory with System Dependent bandwidth, a structural limitation that can throttle performance under memory-intensive workloads.

The texture and pixel throughput numbers reinforce the GT 1010's edge in certain pipelines. The GT 1010 reaches 23.49 GTexel/s and 11.74 GPixel/s, while the Iris Pro manages 38.40 GTexel/s but only 4.800 GPixel/s. The Iris Pro's higher texture rate is a genuine advantage in texture-bound scenarios, but its pixel rate is less than half of the GT 1010's, which explains its weaker overall compute showing in the OpenCL test.

The Verdict

The data points to a clear overall winner for compute-bound workloads: the NVIDIA GeForce GT 1010. Its 6698 OpenCL score beats the Iris Pro's 5712 by 17.3%, and it holds a higher percentile rank (38th versus 33rd). For any task that relies on raw shader throughput, pixel fill, or memory bandwidth, the GT 1010 is the stronger part.

However, the verdict is not universal. The Iris Pro Graphics P6300 is an integrated processor graphics solution with a 15 W TDP, while the GT 1010 is a discrete single-slot card with a 30 W TDP. The Iris Pro consumes half the power, requires no additional board space beyond the motherboard, and draws its memory from the system pool. For a compact, low-power system where the CPU already includes graphics, the Iris Pro may be the only practical option. But from a pure performance standpoint, the GT 1010 wins the recorded benchmark outright.

The GT 1010 also has a notable architectural edge in API support. It supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4, whereas the Iris Pro supports DirectX 12 (11_1), OpenGL 4.4, and Vulkan 1.0. For modern titles that leverage newer API features, the GT 1010 is better equipped. The GT 1010 also has a higher FP32 throughput at 751.6 GFLOPS versus 614.4 GFLOPS, a 22.3% raw compute advantage that aligns closely with the observed benchmark delta.

Where Each One Wins

The GeForce GT 1010 wins in every measured category that matters for general compute and gaming. It has higher FP32 performance (751.6 GFLOPS versus 614.4 GFLOPS), higher pixel rate (11.74 GPixel/s versus 4.800 GPixel/s), and higher memory bandwidth (48.06 GB/s versus System Dependent). It also has dedicated GDDR5 memory, which provides predictable latency and bandwidth characteristics compared to shared system memory. The GT 1010's 256 shading units and 16 TMUs are fewer than the Iris Pro's 384 shading units and 48 TMUs, but the clock speed advantage (1468 MHz boost versus 800 MHz boost) more than compensates in the recorded benchmark.

The Iris Pro Graphics P6300 wins on efficiency and integration. Its 15 W TDP is half the GT 1010's 30 W TDP. It is an IGP with no power connectors and no separate slot requirement, making it suitable for ultra-compact or low-power builds. Its texture rate of 38.40 GTexel/s is significantly higher than the GT 1010's 23.49 GTexel/s, which could give it an edge in texture-heavy workloads that are not reflected in the OpenCL score. The Iris Pro also uses a Ring Bus interface and is built on the same 14 nm process (Intel's foundry versus Samsung for the GT 1010), though the GT 1010's transistor density of 24.3M per mm² on a 74 mm² die is a notable engineering contrast.

For gaming, the GT 1010 is the better choice based on the data. It has a higher pixel rate, higher memory bandwidth, and better API support. The Iris Pro's higher texture rate is its only clear performance advantage, and that alone does not compensate for the 17.3% compute deficit.

Architecture Differences

The two GPUs come from fundamentally different design philosophies. The GeForce GT 1010 is a discrete graphics card built on NVIDIA's Pascal architecture, using the GP108 chip. It is fabricated on Samsung's 14 nm process and packs 1,800 million transistors into a 74 mm² die, yielding a transistor density of 24.3 million per mm². The Iris Pro Graphics P6300 is an integrated processor graphics solution based on Intel's Broadwell GT3e chip, using the Generation 8.0 architecture. It is also built on a 14 nm process, but Intel is the foundry, and no transistor count or die size is recorded in the database.

The execution resources differ significantly. The GT 1010 has 256 shading units, 16 texture mapping units, and 8 ROPs. The Iris Pro has 384 shading units, 48 TMUs, and 6 ROPs. The Iris Pro's larger shader count and TMU count suggest it was designed for broader parallel throughput, but its clock speeds are dramatically lower: 300 MHz base and 800 MHz boost versus 1228 MHz base and 1468 MHz boost for the GT 1010. The result is that the GT 1010 achieves 751.6 GFLOPS of FP32 compute, while the Iris Pro manages 614.4 GFLOPS.

Memory architecture is another major divider. The GT 1010 uses dedicated GDDR5 memory with a 64-bit bus and 48.06 GB/s of bandwidth. The Iris Pro relies on System Shared memory, with the bus width and bandwidth listed as System Dependent. This means the Iris Pro's memory performance is tied to the host system's configuration, which can vary widely and is generally far slower than dedicated GDDR5.

The GT 1010 is a single-slot card with no power connectors and a suggested PSU of 200 W. It uses a PCIe 3.0 x4 bus interface and has display outputs of 1x DVI and 1x mini-HDMI 2.0. The Iris Pro is an IGP with a Ring Bus interface, motherboard-dependent display outputs, and no power connectors at all. Its 15 W TDP is half the GT 1010's 30 W TDP.

In terms of feature support, the GT 1010 has a higher DirectX feature level (12_1 versus 11_1), newer OpenGL support (4.6 versus 4.4), and a much newer Vulkan version (1.4 versus 1.0). The GT 1010 also has a distinct generation identity: it belongs to the GeForce 10 series, was released on 2021-01-12, and follows the GeForce 900 series as its predecessor and the GeForce 20 series as its successor. The Iris Pro was released on 2014-09-04, has no recorded predecessor or successor, and is part of the HD Graphics-W (Broadwell generation.

Neither GPU has ray tracing cores, tensor cores, FP16 performance data, or a launch MSRP in the database. Both are marked end-of-life in terms of production status. The GT 1010's release date of 2021-01-12 makes it a much newer product than the Iris Pro's 2014-09-04 release, a gap that is reflected in its superior API support and memory technology. The Iris Pro's only clear architectural advantages are its higher texture rate and lower power draw, alongside its integrated nature that eliminates the need for a separate slot or power delivery hardware.
