AMD Radeon RX 7650 GRE vs NVIDIA GeForce RTX 4080 Comparison

Head-to-Head Benchmarks

The recorded data contains two shared benchmark results between the NVIDIA GeForce RTX 4080 and the AMD Radeon RX 7650 GRE, and the NVIDIA card wins both by substantial margins. In the 3DMark Steel Nomad DX12 test, the RTX 4080 scores 6,567 points against the RX 7650 GRE's 2,336 points. That is a delta of 181.1%, meaning the RTX 4080 more than doubles the AMD card's performance in this DirectX 12 workload. The gap is not a narrow edge; it is a dominant, category-level difference.

The second shared test, Geekbench OpenCL, tells a similar story. The RTX 4080 records 214,739 points, while the RX 7650 GRE manages 83,109 points. The delta here is 158.4%, again placing the NVIDIA card far ahead. This is a compute-oriented workload, and the RTX 4080's larger shader array and higher memory bandwidth translate into a massive advantage. The RX 7650 GRE is not within striking distance in either test.

Looking at the broader database averages, the RTX 4080 holds an average benchmark score of 54,247 across all its recorded tests, while the RX 7650 GRE averages 42,723. That is a difference of roughly 27% in favor of the RTX 4080, though the two cards sit in different competitive tiers. The RTX 4080's nearest rivals include the RTX 4080 SUPER (delta 0.1%), the AMD Radeon Pro W5700X (delta -1.1%), and the AMD Radeon RX 6750 GRE 12 GB (delta -2.6%). The RX 7650 GRE's nearest rivals are the RTX 4070 SUPER (delta -1.2%), the Quadro M6000 24 GB (delta -1.2%), and the RTX 5050 Mobile (delta -1.3%). These lists show that the RX 7650 GRE competes in a much lower performance bracket, despite its high percentile ranking.

The percentile data reinforces the separation. The RTX 4080 sits at the 86th percentile of all GPUs in the database, while the RX 7650 GRE sits at the 83rd percentile. That three-point difference in percentile may seem small, but the absolute score gap is enormous. Percentile rankings compress near the top end, so a three-point percentile gap can represent a very large raw performance difference. The head-to-head results confirm this: the RTX 4080 is not merely faster, it is in a different performance class.

Architecture Differences

The two cards come from fundamentally different architectural designs. The RTX 4080 uses the AD103 chip based on NVIDIA's Ada Lovelace architecture, built on a 5 nm process at TSMC. The RX 7650 GRE uses the Navi 33 chip based on AMD's RDNA 3.0 architecture, built on a 6 nm process, also at TSMC. The process node difference is meaningful: 5 nm versus 6 nm gives the NVIDIA chip a density advantage, though the AMD chip is much smaller in absolute terms.

The transistor counts highlight the scale difference. The RTX 4080 packs 45,900 million transistors on a die size of 379 mm², yielding a transistor density of 121.1 million per mm². The RX 7650 GRE has 13,300 million transistors on a 204 mm² die, with a density of 65.2 million per mm². The RTX 4080 is not only larger, it is also more densely packed, which explains part of its performance lead.

The memory subsystems differ completely. The RTX 4080 uses 16 GB of GDDR6X on a 256-bit bus, achieving 716.8 GB/s of bandwidth. The RX 7650 GRE uses 8 GB of GDDR6 on a 128-bit bus, achieving 288.0 GB/s. The bus width is halved, the memory type is slower, and the capacity is halved. This is a structural difference, not a tuning difference.

The compute resources diverge sharply. The RTX 4080 has 9,728 shading units, 304 texture mapping units, 112 render output units, 76 ray tracing cores, and 304 tensor cores. The RX 7650 GRE has 2,048 shading units, 128 TMUs, 64 ROPs, and 32 ray tracing cores, with no tensor cores listed. The RTX 4080 also supports NVIDIA's tensor core technology, which the RX 7650 GRE lacks entirely. The pixel rate for the RTX 4080 is 280.6 GPixel/s, versus 172.5 GPixel/s for the RX 7650 GRE. The texture rate is 761.5 GTexel/s versus 345.0 GTexel/s.

The API support is identical: both cards support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The RTX 4080 uses a PCIe 4.0 x16 interface, while the RX 7650 GRE uses PCIe 4.0 x8. The x8 link halves the available bandwidth to the host system, which can matter in some CPU-bound scenarios, though the database does not include specific tests for that.

Specification Differences

The most obvious specification gap is memory. The RTX 4080 has 16 GB of GDDR6X on a 256-bit bus with 716.8 GB/s bandwidth. The RX 7650 GRE has 8 GB of GDDR6 on a 128-bit bus with 288.0 GB/s. This is a 2x difference in capacity and a roughly 2.5x difference in bandwidth.

The clock speeds differ in interesting ways. The RTX 4080 has a base clock of 2,205 MHz and a boost clock of 2,505 MHz. The RX 7650 GRE has a lower base clock of 1,720 MHz but a higher boost clock of 2,695 MHz, plus a game clock of 2,350 MHz. The AMD card boosts higher, but the NVIDIA card maintains a much higher base clock, which can matter for sustained workloads.

The power requirements are starkly different. The RTX 4080 has a TDP of 320 W and requires a 700 W power supply, using a single 16-pin connector. The RX 7650 GRE has a TDP of 170 W and requires a 450 W power supply, using a single 8-pin connector. The RX 7650 GRE draws less than half the power of the RTX 4080, which affects system build requirements and thermal output.

Physical dimensions also differ. The RTX 4080 is 310 mm long, 140 mm tall, and 61 mm wide, and takes up a triple-slot space. The RX 7650 GRE is 204 mm long and 115 mm tall, with no width listed, and takes up a dual-slot space. The RX 7650 GRE is substantially shorter and lower profile, making it easier to fit in smaller cases.

The display outputs differ. The RTX 4080 offers 1x HDMI 2.1 and 3x DisplayPort 1.4a. The RX 7650 GRE offers 1x HDMI 2.1a and 3x DisplayPort 2.1. The AMD card supports the newer DisplayPort 2.1 standard, which is a notable advantage for future high-refresh-rate monitors.

The RTX 4080 was released on 2022-09-19, while the RX 7650 GRE was released on 2025-02-06. The RTX 4080 is end-of-life, and its successor is the GeForce 50 series. The RX 7650 GRE is active, and its successor is Navi IV. The RTX 4080's launch MSRP is 1,199 USD, and the RX 7650 GRE's launch MSRP is 279 USD.

The Verdict

The data is unambiguous. The RTX 4080 wins both head-to-head benchmarks by margins exceeding 150%, and its average benchmark score is about 27% higher than the RX 7650 GRE. The RTX 4080 is the faster card in every measured dimension: more shading units, more memory bandwidth, more texture units, and more ray tracing cores. It sits at the 86th percentile versus the 83rd percentile for the RX 7650 GRE.

However, the verdict depends on what the user prioritizes. The RTX 4080 is a high-end card with a 320 W TDP, a triple-slot footprint, and a launch MSRP of 1,199 USD. The RX 7650 GRE is a mid-range card with a 170 W TDP, a dual-slot footprint, and a launch MSRP of 279 USD. The RX 7650 GRE is also currently in active production, while the RTX 4080 is end-of-life. If the user needs maximum performance and has the power and space budget, the RTX 4080 is the clear choice. If the user needs a smaller, lower-power card that is still actively sold, the RX 7650 GRE is the only one of the two that fits that profile.

The percentile rankings show that both cards are above average in the database, but the RTX 4080 is in a different league. The nearest rivals for the RTX 4080 are all within a few percent of its average score, which shows how competitive the high end is. The nearest rivals for the RX 7650 GRE are also within a few percent, but that cluster sits at a much lower absolute score level.

Where Each One Wins

The RTX 4080 wins in raw performance. It dominates the 3DMark Steel Nomad DX12 test by 181.1% and the Geekbench OpenCL test by 158.4%. It has more than double the memory bandwidth, more than four times the shading units, and more than double the texture fill rate. For any workload that stresses the GPU, the RTX 4080 is the winner.

The RX 7650 GRE wins in efficiency and physical footprint. It has a TDP of 170 W versus 320 W, which means it generates less heat and requires a smaller power supply (450 W versus 700 W). It is a dual-slot card versus a triple-slot card, and it is 204 mm long versus 310 mm long. It uses a single 8-pin connector instead of a 16-pin connector, which is more compatible with older power supplies. It also supports DisplayPort 2.1, while the RTX 4080 only supports DisplayPort 1.4a.

The RX 7650 GRE also wins on production status. It is active, while the RTX 4080 is end-of-life. For a user buying new hardware today, the RX 7650 GRE is a current product. The RTX 4080 is a previous-generation card with a successor already in the market.

In terms of use cases, the RTX 4080 is for high-resolution gaming, heavy compute tasks, and ray tracing workloads where its 76 RT cores and 304 tensor cores can be utilized. The RX 7650 GRE is for 1080p or 1440p gaming in smaller builds, where its lower power draw and compact size are advantages. The data does not show how each card performs in specific games, but the raw benchmark scores strongly favor the RTX 4080 in any GPU-bound scenario.
