AMD Radeon RX 7650 GRE vs AMD Radeon RX 7900 GRE Comparison

Head-to-Head Benchmarks

The recorded data contains two direct benchmark comparisons between the AMD Radeon RX 7650 GRE and the AMD Radeon RX 7900 GRE. Both tests show a decisive advantage for the RX 7900 GRE, with the RX 7650 GRE failing to secure a single win across the two recorded workloads.

In the 3DMark Steel Nomad DX12 test, the RX 7900 GRE scores 4814 points, while the RX 7650 GRE scores 2336 points. The delta percentage of -51.5% indicates the RX 7650 GRE trails by more than half in this DirectX 12 workload. This is a substantial margin that reflects a fundamental difference in raw graphics throughput between the two cards.

The Geekbench OpenCL test shows a similar pattern. The RX 7900 GRE posts a score of 175758, while the RX 7650 GRE reaches 83109. The delta here is -52.7%, meaning the RX 7650 GRE delivers less than half the compute performance in this OpenCL benchmark. Across both recorded tests, the RX 7650 GRE averages a 52.1% deficit relative to the RX 7900 GRE.

Looking at broader database positioning, the RX 7650 GRE holds an 83rd percentile rank among all GPUs, with an average benchmark score of 42723. Its nearest rivals include the NVIDIA GeForce RTX 4070 SUPER at 43223 (a -1.2% delta), the NVIDIA Quadro M6000 24 GB at 43262 (-1.2%), the NVIDIA GeForce RTX 5050 Mobile at 43268 (-1.3%), and the NVIDIA Quadro M6000 at 43301 (-1.3%). These narrow deltas place the RX 7650 GRE in a competitive band where differences of roughly one percent separate adjacent cards.

The RX 7900 GRE, by contrast, sits at the 77th percentile with an average benchmark score of 32456. Its nearest rivals are the AMD FirePro S10000 at 32388 (a +0.2% delta for the RX 7900 GRE), the AMD FirePro S9300 X2 at 32540 (-0.3% delta), the AMD Radeon RX 590 GME at 32601 (-0.4%), and the AMD Radeon Pro 570X at 32176 (+0.9%). The RX 7900 GRE's average score is lower than the RX 7650 GRE's average score, yet its direct head-to-head results are dramatically higher. This discrepancy stems from the different benchmark suites each card was subjected to; the RX 7900 GRE has a much larger set of recorded tests, including several PassMark workloads that pull its average down, whereas the RX 7650 GRE only has two recorded tests, both of which are relatively strong for its class.

The head-to-head data confirms that in the two shared workloads, the RX 7900 GRE is the clear victor. The 3DMark Steel Nomad DX12 result, with its 51.5% gap, indicates that the RX 7900 GRE handles modern DirectX 12 rendering with far greater headroom. The Geekbench OpenCL result, with its 52.7% gap, shows the compute advantage is equally pronounced. These are not marginal differences; they represent a full performance tier separation.

Architecture Differences

The two cards share the same RDNA 3.0 architecture and belong to the same Radeon RX 7000 series, yet they are built on fundamentally different silicon. The RX 7650 GRE uses the Navi 33 chip, codenamed Hotpink Bonefish, fabricated on a 6 nm process at TSMC. The RX 7900 GRE uses the Navi 31 chip, codenamed Plum Bonito, fabricated on a 5 nm process, also at TSMC. The process node difference is modest but contributes to significant disparities in transistor counts and die sizes.

The RX 7650 GRE packs 13,300 million transistors onto a 204 mm² die, yielding a transistor density of 65.2 million per square millimeter. The RX 7900 GRE contains 57,700 million transistors on a 529 mm² die, with a density of 109.1 million per square millimeter. The RX 7900 GRE's die is more than 2.5 times larger by area, and its transistor density is nearly 70% higher, indicating a much more complex and capable silicon design.

Memory configurations diverge sharply. The RX 7650 GRE has 8 GB of GDDR6 memory on a 128-bit bus, delivering 288.0 GB/s of bandwidth. The RX 7900 GRE doubles capacity to 16 GB of GDDR6, doubles the bus width to 256 bit, and exactly doubles bandwidth to 576.0 GB/s. Both cards run memory at 2250 MHz with 18 Gbps effective speed, but the wider bus on the RX 7900 GRE is the decisive factor.

Compute resources scale accordingly. The RX 7650 GRE has 2048 shading units, 128 texture mapping units, 64 render output units, and 32 ray tracing cores. The RX 7900 GRE has 5120 shading units, 320 TMUs, 160 ROPs, and 80 RT cores. Each of these counts is roughly 2.5 times higher on the RX 7900 GRE. Pixel rate jumps from 172.5 GPixel/s on the RX 7650 GRE to 359.2 GPixel/s on the RX 7900 GRE. Texture rate jumps from 345.0 GTexel/s to 718.4 GTexel/s. FP32 throughput more than doubles, from 22.08 TFLOPS to 45.98 TFLOPS. FP16 performance differs in ratio as well: the RX 7650 GRE delivers 22.08 TFLOPS at a 1:1 ratio with FP32, while the RX 7900 GRE delivers 91.96 TFLOPS at a 2:1 ratio. This means the RX 7900 GRE has a dedicated FP16 advantage that the RX 7650 GRE does not possess.

Clock speeds tell a different story. The RX 7650 GRE runs at a base clock of 1720 MHz, a game clock of 2350 MHz, and a boost clock of 2695 MHz. The RX 7900 GRE has lower clocks across the board: 1287 MHz base, 1880 MHz game, and 2245 MHz boost. The RX 7650 GRE's higher clocks partially compensate for its smaller compute array, but the sheer scale of the RX 7900 GRE's resources overwhelms the clock advantage. The RX 7650 GRE uses a single 8-pin power connector with a 170 W TDP and a suggested 450 W PSU. The RX 7900 GRE requires two 8-pin connectors, draws 260 W TDP, and recommends a 600 W PSU.

Interface and output differences also exist. The RX 7650 GRE connects via PCIe 4.0 x8, while the RX 7900 GRE uses PCIe 4.0 x16. Display outputs differ: the RX 7650 GRE has one HDMI 2.1a and three DisplayPort 2.1 outputs, while the RX 7900 GRE has one HDMI 2.1a, two DisplayPort 2.1 outputs, and one USB Type-C port. Physical dimensions diverge substantially: the RX 7650 GRE measures 204 mm in length and 115 mm in height, while the RX 7900 GRE is 276 mm long, 110 mm high, and 51 mm wide. Both cards are dual-slot designs.

The API support is identical: both claim DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The release dates differ, with the RX 7650 GRE arriving on 2025-02-06 and the RX 7900 GRE on 2023-07-26. Both list their predecessor as Navi II and successor as Navi IV, and both remain in active production.

Where Each One Wins

The RX 7900 GRE wins both recorded head-to-head benchmarks, and the margin is consistent across DirectX 12 and OpenCL workloads. For applications that stress raw compute throughput, high memory bandwidth, or large frame buffers, the RX 7900 GRE is the appropriate choice. Its 16 GB memory capacity and 576.0 GB/s bandwidth provide double the resources of the RX 7650 GRE, which matters for high-resolution textures and compute-heavy workloads. The 5120 shading units, 320 TMUs, and 80 RT cores give it a substantial advantage in rendering tasks that scale with parallel execution units.

The RX 7650 GRE has strengths that are not captured in the head-to-head results. Its higher boost clock of 2695 MHz versus 2245 MHz on the RX 7900 GRE suggests better performance in lightly threaded or clock-bound scenarios. Its lower TDP of 170 W versus 260 W makes it less demanding on power delivery, and its single 8-pin connector simplifies installation compared to the dual 8-pin requirement of the RX 7900 GRE. The RX 7650 GRE is also physically smaller at 204 mm length versus 276 mm, which aids compatibility with compact chassis. Its higher average benchmark score of 42723 relative to 32456 for the RX 7900 GRE, combined with its 83rd percentile rank, indicates that in the broader database context, it performs well against the full spectrum of GPUs. The RX 7650 GRE's nearest rivals are all within 1.3% of its score, meaning it competes in a tightly packed performance band, while the RX 7900 GRE's nearest rivals show a similar tight clustering around its lower average.

For users prioritizing absolute performance in the two recorded workloads, the RX 7900 GRE is the clear winner. For scenarios where lower power draw, smaller physical footprint, or higher clock speeds matter more, the RX 7650 GRE offers advantages. The RX 7650 GRE also has a launch MSRP of 279 USD, while the RX 7900 GRE has a launch MSRP of 549 USD, a difference that reflects their respective performance tiers. The data does not show any workload where the RX 7650 GRE outperforms the RX 7900 GRE, so any selection between them must weigh the RX 7650 GRE's efficiency and size benefits against the RX 7900 GRE's dominant compute and memory capabilities.
