AMD Radeon RX 7650 GRE vs NVIDIA RTX A1000 Mobile Comparison

The NVIDIA RTX A1000 Mobile and AMD Radeon RX 7650 GRE occupy entirely different corners of the GPU market, and the benchmark data reflects that split. The AMD card, a desktop dual-slot model from the Radeon RX 7000 series, dominates the single available head-to-head test, delivering a Geekbench OpenCL score of 83109 against the NVIDIA mobile part's 48703—a commanding 41.4% advantage. However, the RTX A1000 Mobile, an end-of-life IGP for portable devices, holds a higher overall percentile rank (85th vs. 83rd) and a higher average benchmark score (47743 vs. 42723) across all tested GPUs, driven by its distinct benchmark profile. The data suggests the RX 7650 GRE is the clear performance winner in raw compute, while the RTX A1000 Mobile offers a more energy-efficient, integrated solution for mobile workstations.

The Verdict

Based strictly on the provided data, the AMD Radeon RX 7650 GRE is the superior choice for users prioritizing raw compute performance. Its Geekbench OpenCL score of 83109 is 41.4% higher than the RTX A1000 Mobile's 48703, a massive gap that translates to significantly faster rendering, compute, and general GPU-accelerated workloads. The RX 7650 GRE also offers double the memory capacity (8 GB vs. 4 GB) and substantially higher memory bandwidth (288.0 GB/s vs. 176.0 GB/s), which are critical for texture-heavy and large-dataset tasks.

However, the RTX A1000 Mobile is not without its merits. As an IGP (integrated graphics processor) with a 60 W TDP, it is designed for power-constrained mobile devices, whereas the RX 7650 GRE is a 170 W dual-slot desktop card requiring a 450 W power supply and an 8-pin connector. For a laptop user needing a capable GPU that sips power, the RTX A1000 Mobile is the only viable option in this comparison. Its 85th percentile ranking versus all GPUs is also higher than the RX 7650 GRE's 83rd percentile, indicating that its overall benchmark performance is competitive within the broader GPU landscape.

The verdict is clear: choose the RX 7650 GRE for any desktop build where performance is the sole criterion. Choose the RTX A1000 Mobile only if you are constrained to a mobile form factor and require an integrated solution with minimal power draw. The data does not support any other conclusion—the RX 7650 GRE wins the only direct benchmark by a landslide, while the RTX A1000 Mobile's advantages are purely in efficiency and portability.

FAQ

Q: Which GPU has the higher raw compute performance?

A: The AMD Radeon RX 7650 GRE is decisively faster. In the Geekbench OpenCL test, it scores 83109 versus the NVIDIA RTX A1000 Mobile's 48703, a 41.4% difference. Its FP32 compute rate is also far higher at 22.08 TFLOPS compared to 4.669 TFLOPS.

A: The AMD Radeon RX 7650 GRE has a launch MSRP of 279 USD. The RTX A1000 Mobile has no listed launch MSRP.

Architecture Differences

The two GPUs represent fundamentally different design philosophies from their respective manufacturers. The NVIDIA RTX A1000 Mobile is built on the Ampere architecture, using the GA107 chip manufactured by Samsung on an 8 nm process node. This chip integrates 8,700 million transistors across a 200 mm² die, resulting in a transistor density of 43.5M per mm². Ampere's key features include dedicated RT cores (16 in this chip) for ray tracing and tensor cores (64) for AI acceleration, supporting DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

In contrast, the AMD Radeon RX 7650 GRE is based on the RDNA 3.0 architecture, using the Navi 33 chip (codename "Hotpink Bonefish") manufactured by TSMC on a more advanced 6 nm process. This chip packs 13,300 million transistors into a 204 mm² die, achieving a significantly higher transistor density of 65.2M per mm². RDNA 3.0 also includes 32 RT cores but notably lacks tensor cores, as AMD relies on different compute pathways. It supports the same API suite: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

The architectural divergence is stark. The NVIDIA part is a mobile-focused, power-optimized design with dedicated AI hardware, while the AMD part is a desktop-oriented, performance-maximizing chip with double the RT cores. The process node difference (6 nm vs. 8 nm) and transistor count (13,300M vs. 8,700M) give the AMD chip a substantial raw hardware advantage, which is reflected in its compute throughput (22.08 TFLOPS FP32 vs. 4.669 TFLOPS). The RTX A1000 Mobile's tensor cores, absent on the AMD card, suggest a focus on AI workloads, but the data does not include benchmarks for that specific capability.

Specification Differences

The specification sheets reveal a comprehensive advantage for the AMD Radeon RX 7650 GRE in nearly every measurable performance metric. The most significant differences are in clock speeds, memory, and compute rates. The RX 7650 GRE operates at a base clock of 1720 MHz and boosts to 2695 MHz, with a game clock of 2350 MHz. The RTX A1000 Mobile is far slower, with a 630 MHz base and 1140 MHz boost. Memory clocks also differ: the AMD card runs at 2250 MHz (18 Gbps effective) versus the NVIDIA's 1375 MHz (11 Gbps effective).

Memory capacity and bandwidth are doubled or better on the AMD side: 8 GB vs. 4 GB, and 288.0 GB/s vs. 176.0 GB/s, respectively. Texture and pixel rates are dramatically higher on the RX 7650 GRE (345.0 GTexel/s and 172.5 GPixel/s) compared to the RTX A1000 Mobile (72.96 GTexel/s and 36.48 GPixel/s). The AMD card also has more TMUs (128 vs. 64) and ROPs (64 vs. 32), though both have 2048 shading units. The RTX A1000 Mobile has 64 tensor cores and 16 RT cores, while the RX 7650 GRE has 32 RT cores and no tensor cores.

Physical and power specifications differ as expected for a mobile versus desktop part. The RTX A1000 Mobile is an IGP with a 60 W TDP, no power connectors, and a PCIe 4.0 x8 interface. The RX 7650 GRE is a dual-slot card measuring 204 mm in length, with a 170 W TDP, a single 8-pin power connector, a suggested 450 W PSU, and the same PCIe 4.0 x8 interface. Display outputs also differ: the AMD card offers 1x HDMI 2.1a and 3x DisplayPort 2.1, while the NVIDIA's outputs are "Portable Device Dependent." Production status and release dates are also distinct: the RTX A1000 Mobile is end-of-life, released on 2022-03-29, while the RX 7650 GRE is active, released on 2025-02-06.

Head-to-Head Benchmarks

The single head-to-head benchmark available in the data is Geekbench OpenCL, and it delivers a decisive result: the AMD Radeon RX 7650 GRE wins with a score of 83109, while the NVIDIA RTX A1000 Mobile scores 48703. The delta is -41.4% from the AMD card's perspective, meaning the NVIDIA part is 41.4% slower. This is a massive performance gap that aligns with the specification differences, particularly the 4.7x higher FP32 throughput (22.08 TFLOPS vs. 4.669 TFLOPS) and significantly higher memory bandwidth.

The RTX A1000 Mobile does have a second benchmark in its profile—a Geekbench Vulkan score of 46782—but there is no comparable Vulkan result for the RX 7650 GRE in the head-to-head data, so it cannot be directly compared. The AMD card's other benchmark (3DMark Steel Nomad DX12, score 2336) also lacks a counterpart on the NVIDIA side. In the absence of further head-to-head tests, the Geekbench OpenCL result stands as the sole comparative data point, and it strongly favors the AMD card.

Looking at the nearest rivals for context, the RTX A1000 Mobile's average score of 47743 is 1.5% below the AMD Radeon RX 6800 XT (48477) and 2.2% above the AMD Radeon RX 6550M (46702). The RX 7650 GRE's average score of 42723 is 1.2% below the NVIDIA GeForce RTX 4070 SUPER (43223) and 1.3% below the NVIDIA GeForce RTX 5050 Mobile (43268). These figures show that while the RX 7650 GRE wins the head-to-head decisively, its average score across all benchmarks is lower than the RTX A1000 Mobile's, suggesting the AMD card's performance is more variable across different tests. The data, however, does not provide those additional test results, leaving the OpenCL score as the definitive comparative measure.
