AMD Radeon RX 7650 GRE vs AMD Radeon RX 7800 XT Comparison

# The Verdict

The AMD Radeon RX 7800 XT and AMD Radeon RX 7650 GRE serve entirely different positions within the Radeon RX 7000 series. The RX 7800 XT is the substantially larger and more powerful card, built on the Navi 32 chip with 3,840 shading units, 16 GB of GDDR6 memory on a 256-bit bus, and a 624.1 GB/s memory bandwidth. The RX 7650 GRE uses the smaller Navi 33 chip with 2,048 shading units, 8 GB of GDDR6 memory on a 128-bit bus, and 288.0 GB/s bandwidth. The recorded data shows the RX 7800 XT delivers a 3DMark Steel Nomad DX12 score of 4,157 versus 2,336 for the RX 7650 GRE, a 43.8% advantage for the larger card.

The RX 7650 GRE, however, posts a Geekbench OpenCL score of 83,109 against 18,290 for the RX 7800 XT, a 354.4% margin in favor of the smaller card. This split result means the verdict depends entirely on the workload. The RX 7800 XT is the choice for rasterized gaming and DirectX 12 workloads where the 3DMark Steel Nomad metric applies. The RX 7650 GRE is the choice for OpenCL compute tasks where its score dramatically exceeds the RX 7800 XT.

The database percentile rankings place the RX 7650 GRE in the 83rd percentile across all GPUs with an average benchmark score of 42,723, while the RX 7800 XT sits in the 51st percentile with an average score of 11,627. The RX 7650 GRE's nearest rivals include the NVIDIA GeForce RTX 4070 SUPER at 43,223 (1.2% higher), the NVIDIA Quadro M6000 24 GB at 43,262 (1.2% higher), the NVIDIA GeForce RTX 5050 Mobile at 43,268 (1.3% higher), and the NVIDIA Quadro M6000 at 43,301 (1.3% higher). The RX 7800 XT's nearest rivals include the NVIDIA GeForce GTX 1660 at 11,680 (0.5% lower), the AMD Radeon Pro 5500M at 11,528 (0.9% higher), the NVIDIA Tesla K20c at 11,479 (1.3% higher), and the AMD Radeon RX 6500 XT at 11,842 (1.8% lower). The RX 7650 GRE competes with upper-midrange cards from the previous generation, while the RX 7800 XT sits near entry-level cards in the aggregate database.

# Architecture Differences

Both cards use the RDNA 3.0 architecture and belong to the Navi III (RX 7000) generation, manufactured by TSMC. The process nodes differ: the RX 7650 GRE uses a 6 nm process while the RX 7800 XT uses a 5 nm process. The transistor counts reflect the size gap. The RX 7650 GRE packs 13,300 million transistors on a 204 mm² die, yielding a transistor density of 65.2 million per mm². The RX 7800 XT contains 28,100 million transistors on a 346 mm² die, with a density of 81.2 million per mm². The RX 7800 XT has more than double the transistor count and a considerably larger die area.

Clock behavior differs notably. The RX 7650 GRE has a base clock of 1720 MHz, a game clock of 2350 MHz, and a boost clock of 2695 MHz. The RX 7800 XT runs lower clocks: 1295 MHz base, 2124 MHz game, and 2430 MHz boost. The RX 7650 GRE compensates for fewer shaders with higher clock speeds, while the RX 7800 XT relies on a wider configuration.

The memory subsystems diverge sharply. The RX 7650 GRE uses 8 GB of GDDR6 with a 128-bit bus and memory clock of 2250 MHz (18 Gbps effective), producing 288.0 GB/s bandwidth. The RX 7800 XT uses 16 GB of GDDR6 with a 256-bit bus and memory clock of 2438 MHz (19.5 Gbps effective), producing 624.1 GB/s bandwidth. The RX 7800 XT delivers 2.17 times the memory bandwidth of the RX 7650 GRE.

The compute resource counts confirm the hierarchy. The RX 7650 GRE has 2,048 shading units, 128 texture mapping units, 64 render output units, and 32 ray tracing cores. The RX 7800 XT has 3,840 shading units, 240 TMUs, 96 ROPs, and 60 ray tracing cores. In every compute category, the RX 7800 XT holds a decisive advantage.

The power and interface specifications also differ. The RX 7650 GRE has a TDP of 170 W, uses a single 8-pin power connector, and requires a 450 W suggested PSU. The RX 7800 XT has a TDP of 263 W, uses two 8-pin connectors, and requires a 600 W suggested PSU. The RX 7650 GRE uses a PCIe 4.0 x8 interface; the RX 7800 XT uses PCIe 4.0 x16. Physical dimensions vary as well: the RX 7650 GRE measures 204 mm in length and 115 mm in height, while the RX 7800 XT measures 267 mm in length, 111 mm in height, and 50 mm in width. Both cards are dual-slot designs and share identical display outputs: 1x HDMI 2.1a and 3x DisplayPort 2.1.

# Where Each One Wins

The RX 7800 XT wins in the 3DMark Steel Nomad DX12 benchmark with a score of 4,157 versus 2,336 for the RX 7650 GRE, a 43.8% lead. This metric represents DirectX 12 gaming performance, so the RX 7800 XT is the stronger card for modern game titles that rely on DX12 rendering. The RX 7800 XT also has twice the memory capacity (16 GB versus 8 GB), more than double the memory bandwidth (624.1 GB/s versus 288.0 GB/s), and a larger shading unit count (3,840 versus 2,048), which supports higher resolutions and more demanding texture loads.

The RX 7650 GRE wins in the Geekbench OpenCL benchmark with a score of 83,109 versus 18,290 for the RX 7800 XT, a 354.4% advantage. OpenCL performance is relevant for general-purpose GPU compute tasks, including scientific simulations, video encoding, and machine learning workloads that use the OpenCL API. The RX 7650 GRE's higher clocks (boost 2695 MHz versus 2430 MHz) and smaller die size contribute to this result, though the magnitude of the difference suggests the RX 7800 XT's OpenCL driver path or workload characteristics are not favorable in this particular test.

The RX 7650 GRE also achieves a higher aggregate benchmark score in the database. Its average benchmark score is 42,723 versus 11,627 for the RX 7800 XT, placing the RX 7650 GRE in the 83rd percentile of all GPUs and the RX 7800 XT in the 51st percentile. The head-to-head win count is tied at one each, reflecting the workload-dependent nature of the comparison.

# Head-to-Head Benchmarks

The two recorded head-to-head benchmarks produce opposite winners. The 3DMark Steel Nomad DX12 test goes to the RX 7800 XT with a score of 4,157, while the RX 7650 GRE scores 2,336. The delta is 43.8% in favor of the RX 7800 XT. This is a substantial margin that reflects the RX 7800 XT's larger compute configuration: 3,840 shading units, 240 TMUs, 96 ROPs, and 60 ray tracing cores, versus 2,048 shading units, 128 TMUs, 64 ROPs, and 32 ray tracing cores on the RX 7650 GRE.

The Geekbench OpenCL test goes to the RX 7650 GRE with a score of 83,109, while the RX 7800 XT scores 18,290. The delta is 354.4% in favor of the RX 7650 GRE. This is an exceptionally large gap and is the single biggest performance differential in either direction. The RX 7650 GRE's higher clock speeds (2695 MHz boost versus 2430 MHz) and smaller die size (204 mm² versus 346 mm²) may contribute to this result, but the magnitude suggests that the RX 7800 XT's OpenCL implementation in this test is not representative of its overall compute capability.

The average benchmark scores in the database also favor the RX 7650 GRE. Its average of 42,723 is 3.67 times higher than the RX 7800 XT's 11,627. The RX 7650 GRE's nearest rivals in the database are all within 1.3% of its average score: the NVIDIA GeForce RTX 4070 SUPER at 43,223 (1.2% higher), the NVIDIA Quadro M6000 24 GB at 43,262 (1.2% higher), the NVIDIA GeForce RTX 5050 Mobile at 43,268 (1.3% higher), and the NVIDIA Quadro M6000 at 43,301 (1.3% higher). The RX 7800 XT's nearest rivals include the NVIDIA GeForce GTX 1660 at 11,680 (0.5% lower), the AMD Radeon Pro 5500M at 11,528 (0.9% higher), the NVIDIA Tesla K20c at 11,479 (1.3% higher), and the AMD Radeon RX 6500 XT at 11,842 (1.8% lower).

The RX 7800 XT's aggregate score places it in a different competitive tier than the RX 7650 GRE. The RX 7800 XT's nearest rivals include cards like the GTX 1660 and RX 6500 XT, which are entry-level or older midrange products. The RX 7650 GRE's nearest rivals include the RTX 4070 SUPER, a modern upper-midrange card. The 83rd percentile ranking for the RX 7650 GRE versus the 51st percentile for the RX 7800 XT confirms that the aggregate database scores treat the RX 7650 GRE as the higher-performing product overall, despite the RX 7800 XT's dominance in the DirectX 12 gaming test.
