AMD Radeon RX 6650M XT vs AMD Radeon RX 9070 GRE Comparison

Head-to-Head Benchmarks

The only direct comparison recorded between these two GPUs is the Geekbench OpenCL test, and the result is decisive. The AMD Radeon RX 9070 GRE scores 109,309, while the AMD Radeon RX 6650M XT scores 76,904. That places the RX 9070 GRE roughly 29.6% ahead of the RX 6650M XT in this compute-oriented benchmark. A 29.6% margin is substantial, but it is not an overwhelming gap when considering the architectural gulf between the two. The RX 6650M XT is a mobile part from the Radeon RX 6000 series, built for laptops, while the RX 9070 GRE is a desktop-oriented card from the Radeon RX 9000 series. The score difference suggests the newer card has a clear edge in raw OpenCL throughput, but the older part is not entirely outclassed.

To contextualize the RX 9070 GRE’s score, the database shows its nearest rivals include the Intel Arc A580 (average score 57,756, delta of -0.7%), the AMD Radeon RX 5600 OEM (58,085, -1.2%), the Intel Arc A570M (58,239, -1.5%), and the AMD Radeon RX 6950 XT (58,392, -1.8%). The RX 9070 GRE’s average benchmark score is 57,367, which is slightly below all four of those rivals, but the deltas are tiny, less than 2% in every case. This tells a nuanced story: the RX 9070 GRE’s Geekbench OpenCL result is strong, but its aggregate benchmark average is essentially tied with a set of older or lower-tier cards. The RX 6650M XT, by contrast, has an average benchmark score of 76,904, which is identical to its single Geekbench OpenCL score, and it sits in the 91st percentile of all GPUs. The RX 9070 GRE sits in the 87th percentile. Despite the RX 9070 GRE winning the head-to-head, the RX 6650M XT actually ranks higher in the overall percentile distribution, which is a curious inversion worth investigating.

The RX 6650M XT’s nearest rivals include the NVIDIA GeForce RTX 5090 D (77,712, -1%), the AMD Radeon RX 6850M XT (78,940, -2.6%), the NVIDIA Tesla P100 PCIe 12 GB (79,396, -3.1%), and the NVIDIA Tesla P100 PCIe 16 GB (79,605, -3.4%). Notice that the RX 6650M XT’s score is only about 1% below the RTX 5090 D, a flagship desktop card. That is a remarkable result for a mobile GPU from 2022. The data implies that the RX 6650M XT punches far above its class in OpenCL compute tasks, even if its absolute score is lower than the RX 9070 GRE’s.

Where Each One Wins

The RX 9070 GRE wins the only recorded head-to-head benchmark, so in a direct comparison it is the faster card. The 29.6% lead in Geekbench OpenCL suggests it is better suited for workloads that rely on raw compute throughput, such as GPGPU tasks, rendering, or heavy parallel processing. Its higher FP32 throughput of 34.28 TFLOPS, compared to the RX 6650M XT’s 9.896 TFLOPS, aligns with this interpretation. The RX 9070 GRE also has more shading units (3072 versus 2048), more texture mapping units (192 versus 128), and more render output units (96 versus 64). Every specification that feeds raw pixel and texture processing favors the RX 9070 GRE, which explains its higher pixel rate (267.8 GPixel/s versus 154.6 GPixel/s) and texture rate (535.7 GTexel/s versus 309.2 GTexel/s).

The RX 6650M XT, however, wins in a different sense: its percentile ranking. At the 91st percentile of all GPUs, it outperforms the RX 9070 GRE’s 87th percentile. This means that, relative to the entire database of recorded GPUs, the RX 6650M XT is positioned higher. That could be because the RX 6650M XT’s mobile design consumes far less power (120 W TDP versus 220 W TDP), making it a more efficient part in its segment. The RX 6650M XT also has a higher base clock (2068 MHz versus 1420 MHz) and a higher memory clock in effective terms (16 Gbps versus 18 Gbps, but the base is higher). For users who prioritize energy efficiency or who are constrained by laptop thermal limits, the RX 6650M XT’s profile is more favorable.

The RX 9070 GRE wins on memory capacity and bandwidth. It has 12 GB of GDDR6 memory on a 192-bit bus, yielding 432.0 GB/s of bandwidth. The RX 6650M XT has 8 GB of GDDR6 on a 128-bit bus, yielding 256.0 GB/s. For modern games or compute workloads that exceed 8 GB of VRAM, the RX 9070 GRE is the clear choice. The RX 6650M XT’s 8 GB could be a bottleneck in memory-heavy scenarios, even if its compute efficiency is respectable.

Architecture Differences

The two GPUs represent two distinct generations of AMD’s RDNA architecture. The RX 6650M XT uses RDNA 2.0, built on a 7 nm process at TSMC. The RX 9070 GRE uses RDNA 4.0, built on a 4 nm process at the same foundry. The process node shrink is significant: from 7 nm to 4 nm, which allows for a much higher transistor density. The RX 6650M XT has 11,060 million transistors on a 237 mm² die, giving a density of 46.7 million transistors per square millimeter. The RX 9070 GRE has 53,900 million transistors on a 357 mm² die, yielding 151.0 million transistors per square millimeter. That is a 3.2x increase in transistor density, which explains how the RX 9070 GRE packs more than double the FP32 throughput into a modestly larger die.

The chip names differ: Navi 23 for the RX 6650M XT versus Navi 48 for the RX 9070 GRE. The RX 6650M XT belongs to the Navi Mobile generation (RX 6000M), while the RX 9070 GRE belongs to Navi IV (RX 9000). The RX 9070 GRE’s predecessor is listed as Navi III, indicating a direct lineage within the RX 9000 series. The RX 6650M XT’s predecessor is Polaris Mobile, which points back to an even older architecture. The RX 9070 GRE also supports FP16 at a 1:1 ratio, meaning its FP16 throughput equals its FP32 throughput at 34.28 TFLOPS. The RX 6650M XT supports FP16 at a 2:1 ratio, giving it 19.79 TFLOPS FP16, which is double its FP32 of 9.896 TFLOPS. This difference matters for AI or machine learning workloads that rely on half-precision arithmetic.

The ray tracing cores also differ: the RX 6650M XT has 32 RT cores, while the RX 9070 GRE has 48 RT cores. This suggests the newer card is better equipped for ray-traced rendering, though the database does not provide a direct ray tracing benchmark. Both cards support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API compatibility is identical. The bus interface differs: the RX 6650M XT uses PCIe 4.0 x8, while the RX 9070 GRE uses PCIe 5.0 x16. The newer card has twice the lanes and a newer standard, which could reduce data transfer bottlenecks in CPU-bound scenarios.

Specification Differences

The most obvious difference is the form factor. The RX 6650M XT is listed as an IGP (integrated graphics processor) with no power connectors and a slot width of "IGP," meaning it is designed for mobile integration. The RX 9070 GRE is a dual-slot card with two 8-pin power connectors and a suggested PSU of 550 W. The RX 6650M XT has no suggested PSU, as it draws from the laptop’s power delivery. The TDP difference is stark: 120 W for the RX 6650M XT versus 220 W for the RX 9070 GRE, an 83% increase.

Memory configurations diverge clearly. The RX 6650M XT has 8 GB GDDR6 with a 128-bit bus and 256.0 GB/s bandwidth. The RX 9070 GRE has 12 GB GDDR6 with a 192-bit bus and 432.0 GB/s bandwidth. The RX 9070 GRE’s effective memory clock is 18 Gbps, while the RX 6650M XT runs at 16 Gbps effective. The RX 9070 GRE’s base clock is lower (1420 MHz versus 2068 MHz) but its boost clock is higher (2790 MHz versus 2416 MHz). The game clock, which represents typical sustained performance, is 2220 MHz for the RX 9070 GRE versus 2162 MHz for the RX 6650M XT, a narrow 58 MHz difference.

Display outputs differ: the RX 6650M XT is "Portable Device Dependent," meaning outputs vary by laptop design. The RX 9070 GRE offers 1x HDMI 2.1b and 3x DisplayPort 2.1a. Production status also differs: the RX 6650M XT is end-of-life, while the RX 9070 GRE is active. The RX 9070 GRE has a launch MSRP of 549 USD, which can be stated once. The RX 6650M XT has no launch MSRP in the database. The RX 9070 GRE was released in May 2025, while the RX 6650M XT was released in January 2022. The RX 9070 GRE has a higher transistor count, higher density, higher FP32, higher pixel rate, higher texture rate, and more RT cores.

The Verdict

The data points to a clear performance hierarchy. The RX 9070 GRE is the faster GPU in the only direct benchmark recorded, with a 29.6% lead in Geekbench OpenCL. It also wins on every compute specification: higher FP32, higher pixel rate, higher texture rate, more shading units, more TMUs, more ROPs, and more RT cores. For users who need maximum processing power for compute-heavy tasks, 3D rendering, or modern games with high VRAM demands, the RX 9070 GRE is the obvious choice. Its 12 GB memory and 432.0 GB/s bandwidth provide headroom that the RX 6650M XT cannot match.

However, the RX 6650M XT should not be dismissed. Its 91st percentile ranking exceeds the RX 9070 GRE’s 87th percentile, meaning that in the broader context of all GPUs, it holds a higher relative position. Its 120 W TDP makes it far more power-efficient, and its mobile form factor means it can fit into laptops, which the RX 9070 GRE cannot. For users who prioritize portability, energy efficiency, or who work within the constraints of a laptop chassis, the RX 6650M XT is the only viable option here. The RX 9070 GRE is a desktop-only card with a dual-slot design and external power requirements.

The choice ultimately depends on the use case. A desktop user with a 550 W PSU or better, who wants the latest architecture and maximum compute performance, should pick the RX 9070 GRE. A laptop user or someone who values efficiency over raw speed should pick the RX 6650M XT, especially since it is end-of-life but still ranks high in the percentile distribution. The RX 9070 GRE’s active production status and newer release date suggest it will receive longer driver support, but the RX 6650M XT’s competitive OpenCL score shows it remains relevant. The data does not support a universal winner; it supports a situational one.
