AMD Radeon RX 6750 GRE 12 GB vs NVIDIA GeForce RTX 5070 Mobile Comparison

Where Each One Wins

The recorded head-to-head data contains only one shared benchmark result, and it favors the NVIDIA GeForce RTX 5070 Mobile. In Geekbench Vulkan, the RTX 5070 Mobile scores 116,960 against 108,994 for the AMD Radeon RX 6750 GRE 12 GB, a delta of 6.8% in NVIDIA's favor. That single result means the mobile part holds the only direct benchmark victory in the comparison.

Beyond the shared test, the broader database results paint a different competitive picture. The AMD card sits at the 87th percentile among all GPUs, while the RTX 5070 Mobile lands at the 75th percentile. The average benchmark score for the RX 6750 GRE is 55,698, nearly double the 29,928 average of the RTX 5070 Mobile. Those figures indicate that across the full benchmark suite, the desktop AMD part is the stronger overall performer, even though the single overlapping Vulkan test goes the other way.

The wins split by workload type. The RTX 5070 Mobile wins the one cross-platform graphics test, suggesting its Blackwell architecture handles Vulkan compute efficiently. The RX 6750 GRE wins on aggregate performance, as reflected in its average score and percentile ranking. The AMD card also has a clear advantage in raw rasterization throughput, with 13.21 TFLOPS FP32 versus 13.13 TFLOPS for NVIDIA, though that margin is negligible. The real separation comes from memory capacity and bandwidth, where the AMD card fields 12 GB of GDDR6 on a 192-bit bus delivering 432.0 GB/s, versus 8 GB of GDDR7 on a 128-bit bus at 384.0 GB/s.

Architecture Differences

The two GPUs come from different architectural generations and process nodes. AMD uses RDNA 2.0 on a 7 nm TSMC process with the Navi 22 chip, a design from the Radeon RX 6000 series introduced in October 2023. NVIDIA uses Blackwell 2.0 on a 5 nm TSMC process with the GB206 chip, part of the GeForce 50 Mobile line released in April 2025.

The transistor counts and die sizes reveal a fundamental design divergence. The AMD chip packs 17,200 million transistors across a 335 mm² die, yielding a transistor density of 51.3M per mm². The NVIDIA chip packs 21,900 million transistors into just 181 mm², producing a density of 121.0M per mm². The smaller, denser NVIDIA die is consistent with a mobile-focused part built for constrained thermal envelopes.

Shader and compute resources differ significantly. The RX 6750 GRE has 2,560 shading units, 160 texture mapping units, and 64 ROPs, with 40 ray tracing cores. The RTX 5070 Mobile has 4,608 shading units, 144 TMUs, and 48 ROPs, with 36 ray tracing cores and 144 tensor cores. The AMD part relies on a higher clock speed to extract performance, boosting to 2,581 MHz versus 1,425 MHz for NVIDIA. The FP32 output ends up nearly identical: 13.21 TFLOPS for AMD and 13.13 TFLOPS for NVIDIA.

Memory architecture is another clear split. AMD uses 12 GB of GDDR6 with a 192-bit interface, while NVIDIA uses 8 GB of GDDR7 with a 128-bit interface. The AMD memory runs at 18 Gbps effective for 432.0 GB/s bandwidth; the NVIDIA memory runs at 24 Gbps effective for 384.0 GB/s. NVIDIA's GDDR7 achieves higher per-pin data rates but loses on total bandwidth due to the narrower bus.

Power and physical design could not differ more. The RX 6750 GRE is a dual-slot desktop card rated at 250 W, requiring one 6-pin and one 8-pin power connector with a 600 W suggested PSU. The RTX 5070 Mobile is an integrated graphics processor rated at 50 W, using no power connectors. The AMD card measures 267 mm in length, 110 mm in height, and 40 mm in width. The NVIDIA part has no recorded dimensions, as it is designed for portable devices with display output dependent on the host system.

Head-to-Head Benchmarks

The only direct comparison in the database is Geekbench Vulkan. The NVIDIA GeForce RTX 5070 Mobile records 116,960 points, beating the AMD Radeon RX 6750 GRE 12 GB's 108,994 points by 6.8%. This result is notable because the AMD card holds a substantial advantage in nearly every raw specification category that typically drives Vulkan performance: higher clock speeds, more memory bandwidth, and more memory capacity.

The Vulkan win for NVIDIA suggests that the Blackwell architecture's compute scheduling and driver optimization compensate for the hardware deficits. The RTX 5070 Mobile operates at a 907 MHz base and 1,425 MHz boost, far below the AMD card's 2,321 MHz base and 2,581 MHz boost. Yet the NVIDIA part still manages a higher Vulkan score. The 4,608 shading units versus 2,560 for AMD likely contribute, along with the faster 24 Gbps memory signaling.

Outside the single shared benchmark, the aggregate data favors AMD decisively. The RX 6750 GRE's average benchmark score of 55,698 puts it 86.1% ahead of the RTX 5070 Mobile's 29,928. The AMD card's nearest rivals in the database include the AMD Radeon 8060S with a 55,757 average score and a 0.1% delta, the NVIDIA GeForce RTX 5080 at 56,083 with a 0.7% delta, and the AMD Radeon Pro W5700X at 54,828 with a 1.6% delta. The NVIDIA mobile part's nearest rivals include the NVIDIA GeForce RTX 3070 Ti at 29,945 with a 0.1% delta, the NVIDIA GeForce RTX 2080 Ti at 29,783 with a 0.5% delta, and the AMD Radeon RX 6800 at 30,095 with a 0.6% delta.

The performance class separation is stark. The RX 6750 GRE competes against desktop GPUs like the RTX 5080 and RTX 4080, sitting within 2.7% of the latter's 54,247 average score. The RTX 5070 Mobile competes against older flagship desktop parts like the RTX 2080 Ti and RTX 3070 Ti, landing within 1.7% of the AMD Radeon RX 6700's 30,433 average score. These rival groupings confirm that the AMD card targets a higher performance tier entirely.

The pixel rate comparison reinforces the gap: the RX 6750 GRE delivers 165.2 GPixel/s versus 68.40 GPixel/s for the RTX 5070 Mobile, a 141.5% advantage. Texture rate shows the AMD part at 413.0 GTexel/s versus 205.2 GTexel/s, a 101.2% advantage. The AMD card's 26.43 TFLOPS FP16 throughput, achieved through a 2:1 ratio, dwarfs the NVIDIA part's 13.13 TFLOPS at 1:1. These figures explain why the AMD card's average benchmark score sits so far above the NVIDIA mobile part, despite the Vulkan test favoring NVIDIA.

The 250 W power envelope of the AMD card versus the 50 W of the NVIDIA part explains much of the performance disparity. The desktop GPU can sustain far higher clocks and feed its wider memory bus, while the mobile part operates under a strict thermal and power budget. The database records the RTX 5070 Mobile as an integrated graphics processor with no slot width, no power connectors, and no suggested PSU, confirming its role as a low-power laptop component rather than a desktop-class competitor.
