AMD Radeon RX 6750 GRE 12 GB vs NVIDIA RTX A1000 Mobile Comparison

The benchmark data is unequivocal: the AMD Radeon RX 6750 GRE 12 GB is a dramatically faster GPU than the NVIDIA RTX A1000 Mobile. In the only shared benchmark, the AMD part delivers over double the performance, and its average score places it in a far higher performance tier. The NVIDIA card, while a capable mobile workstation part, cannot compete on raw compute output.

Head-to-Head Benchmarks

The single head-to-head benchmark result firmly establishes the performance hierarchy. In the Geekbench Vulkan test, the AMD Radeon RX 6750 GRE 12 GB scores 108,994, while the NVIDIA RTX A1000 Mobile scores 46,782. This represents a 133% delta in favor of the AMD card, meaning it is nearly 2.33 times faster in this API workload. This is not a marginal victory; it is a generational gap in performance output.

The average benchmark scores across all tests tell a similar story. The AMD Radeon RX 6750 GRE 12 GB averages 55,698 points across its benchmark suite, while the NVIDIA RTX A1000 Mobile averages 47,743 points. This translates to a roughly 16.7% advantage for the AMD part on average, though this gap understates the disparity seen in the Vulkan test. The average is pulled closer by the NVIDIA card's OpenCL result of 48,703, which is its strongest showing, but it still falls short of the AMD card's average.

Looking at the competitive landscape, the AMD card's 55,698 average score places it just 0.1% behind the AMD Radeon 8060S and 0.7% behind the NVIDIA GeForce RTX 5080. It sits 1.6% ahead of the AMD Radeon Pro W5700X and 2.7% ahead of the NVIDIA GeForce RTX 4080. This positioning shows the RX 6750 GRE 12 GB is competing in the upper echelon of desktop GPU performance, trading blows with flagship-class parts from both vendors.

The NVIDIA RTX A1000 Mobile, with its 47,743 average, is a different beast. It sits 1.5% behind the AMD Radeon RX 6800 XT, which is a high-end desktop card, but only 2.2% ahead of the AMD Radeon RX 6550M and 2.4% ahead of the Intel Arc A530M, both of which are mobile parts. This indicates that the A1000 Mobile is a solid mid-range performer in the mobile space, but its performance class is fundamentally lower than the desktop-oriented RX 6750 GRE.

The only benchmark where the NVIDIA card posts a competitive score is Geekbench OpenCL, where it achieves 48,703 points. However, this score is still lower than the AMD card's average across all its tests and does not appear in the head-to-head comparison, which only includes the Vulkan test where AMD wins decisively. The data shows a clear and consistent performance advantage for the AMD part.

Architecture Differences

The two GPUs are built on fundamentally different architectures and manufacturing processes. The AMD Radeon RX 6750 GRE 12 GB uses the Navi 22 chip based on the RDNA 2.0 architecture, manufactured on a 7 nm process at TSMC. The NVIDIA RTX A1000 Mobile uses the GA107 chip based on the Ampere architecture, manufactured on an 8 nm process at Samsung. This process difference contributes to the AMD chip's higher transistor density of 51.3M per mm² compared to 43.5M per mm² for the NVIDIA chip.

The physical scale of the chips differs substantially. The AMD GPU integrates 17,200 million transistors on a 335 mm² die, while the NVIDIA GPU integrates 8,700 million transistors on a 200 mm² die. This means the AMD chip has roughly twice the transistor count and a larger silicon area, providing more room for compute resources.

Memory configurations are starkly different. The AMD card features 12 GB of GDDR6 memory on a 192-bit bus, delivering 432.0 GB/s of bandwidth. The NVIDIA card features only 4 GB of GDDR6 memory on a 128-bit bus, delivering 176.0 GB/s of bandwidth. The AMD card has more than double the memory capacity and 2.45 times the memory bandwidth, which is critical for high-resolution textures and data-intensive workloads.

Compute resource allocation also diverges significantly. The AMD GPU packs 2,560 shading units, 160 texture mapping units, and 64 render output units. It also includes 40 ray tracing cores but no dedicated tensor cores. The NVIDIA GPU has 2,048 shading units, 64 TMUs, and 32 ROPs, with 16 ray tracing cores and 64 tensor cores. While the NVIDIA card has tensor cores for AI acceleration, its raw shading and texturing hardware is substantially weaker.

Clock speeds amplify the architectural differences. The AMD card runs at a base clock of 2321 MHz and boosts to 2581 MHz, with a game clock of 2439 MHz. The NVIDIA card runs at a base clock of just 630 MHz and a boost clock of 1140 MHz. This more than 2x boost clock difference, combined with the higher core count, explains the massive gap in compute throughput.

The power envelope reflects these architectural choices. The AMD Radeon RX 6750 GRE 12 GB is rated at 250 W TDP and requires a 600 W power supply, with dual-slot cooling and both 6-pin and 8-pin power connectors. The NVIDIA RTX A1000 Mobile is rated at only 60 W TDP and is an IGP (integrated graphics processor) with no power connectors, designed for portable devices.

Where Each One Wins

The AMD Radeon RX 6750 GRE 12 GB wins decisively in raw graphics performance. Its Geekbench Vulkan score of 108,994 more than doubles the NVIDIA card's 46,782. This indicates a massive advantage in gaming and general-purpose GPU compute workloads that leverage the Vulkan API. The AMD card's 13.21 TFLOPS of FP32 compute, compared to 4.669 TFLOPS for the NVIDIA card, confirms its superiority in traditional shading workloads.

The AMD card also wins in memory-intensive scenarios. With 12 GB of VRAM versus 4 GB, it can handle larger textures, higher resolutions, and more complex scenes without running out of memory. The 432.0 GB/s bandwidth versus 176.0 GB/s further cements this advantage, allowing faster data transfer for high-resolution rendering and large datasets.

The NVIDIA RTX A1000 Mobile wins in the specific domain of AI-accelerated workloads, thanks to its 64 tensor cores. This hardware is designed for deep learning inference and training tasks, which the AMD card lacks entirely. The NVIDIA card also operates at a much lower power draw of 60 W, making it suitable for thin-and-light laptops where the AMD card's 250 W TDP is impossible to accommodate.

The NVIDIA card's mobile form factor is its primary advantage. As an IGP with no dedicated power connectors, it can be integrated into portable devices. The AMD card, with its 267 mm length and dual-slot design, is strictly a desktop component. For users needing GPU acceleration in a portable workstation, the A1000 Mobile is the only viable option between these two.

The Verdict

The data clearly indicates that the AMD Radeon RX 6750 GRE 12 GB is the superior graphics processor for performance-critical applications. Its 133% lead in the Vulkan benchmark and 16.7% higher average score place it in a completely different performance class. The card's 87th percentile ranking among all GPUs, compared to the NVIDIA card's 85th percentile, underscores this gap. Users seeking maximum frame rates, high-resolution gaming, or heavy compute workloads should choose the AMD card without hesitation.

The NVIDIA RTX A1000 Mobile is the appropriate choice only for specific mobile workstation scenarios. Its 64 tensor cores provide AI acceleration capabilities that the AMD card simply does not offer. The 60 W power envelope makes it feasible for laptop integration, where the AMD card's 250 W TDP and power connector requirements render it unsuitable. For professionals who need CUDA-accelerated AI tools on a portable device, the A1000 Mobile is the only option here.

However, for any desktop use case, the AMD card is the clear winner. Its 12 GB memory capacity, 432.0 GB/s bandwidth, and 13.21 TFLOPS FP32 performance are all dramatically superior. The AMD card also holds a higher average benchmark score of 55,698 versus 47,743, and it outperforms the NVIDIA GeForce RTX 4080 by 2.7% in average score, while the A1000 Mobile trails the AMD Radeon RX 6800 XT by 1.5%.
