AMD Radeon 820M vs AMD Radeon RX 7650 GRE Comparison

Head-to-Head Benchmarks

The AMD Radeon 820M and AMD Radeon RX 7650 GRE occupy opposite ends of the graphics spectrum. The 820M is an integrated processor, while the RX 7650 GRE is a dual-slot add-in board. The recorded data shows a complete mismatch in raw compute capability. The RX 7650 GRE delivers 22.08 TFLOPS of FP32 performance, while the 820M produces 716.8 GFLOPS. That is a 30.8x difference in raw floating-point throughput. The pixel rate tells a similar story: the RX 7650 GRE reaches 172.5 GPixel/s, versus 11.20 GPixel/s for the 820M. The texture rate gap is even more pronounced, with the RX 7650 GRE hitting 345.0 GTexel/s against 22.40 GTexel/s for the 820M.

The RX 7650 GRE has 2048 shading units, 128 texture mapping units, and 64 raster operation pipelines. The 820M has 128 shading units, 8 TMUs, and 4 ROPs. The RX 7650 GRE also includes 32 ray tracing cores, while the 820M has 2. Memory bandwidth separates the two decisively. The RX 7650 GRE uses 8 GB of GDDR6 on a 128-bit bus, delivering 288.0 GB/s. The 820M relies on system shared memory, with bandwidth listed as system dependent. The 820M's boost clock is 2800 MHz, which is higher than the RX 7650 GRE's 2695 MHz boost, but that advantage is irrelevant given the massive disparity in execution resources.

In the database, the RX 7650 GRE holds a percentile rank of 83 among all GPUs, while the 820M sits at the 50th percentile. The RX 7650 GRE has two benchmark entries: a 3DMark Steel Nomad DX12 score of 2336 and a Geekbench OpenCL score of 83109. Its average benchmark score is 42723. The 820M has no recorded benchmark entries and an average score of 0.

Against its nearest rivals, the RX 7650 GRE trails the NVIDIA GeForce RTX 4070 SUPER by 1.2%, based on an average rival score of 43223. It also lags the NVIDIA Quadro M6000 24 GB by 1.2%, with that card averaging 43262. The NVIDIA GeForce RTX 5050 Mobile is 1.3% ahead, posting 43268, and the NVIDIA Quadro M6000 is also 1.3% ahead at 43301. These margins are small enough to classify the RX 7650 GRE as effectively tied with those four cards in aggregate scoring, though the specific workload mix determines the actual outcome.

Where Each One Wins

The RX 7650 GRE wins in every measurable compute metric from the database. Its FP32 throughput of 22.08 TFLOPS dwarfs the 820M's 716.8 GFLOPS. Both GPUs support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API feature parity exists. Ray tracing is present on both, but the RX 7650 GRE has 32 ray accelerators versus 2 on the 820M. The RX 7650 GRE also offers dedicated 8 GB of GDDR6 memory, which avoids the performance variability of system shared memory. The 820M's memory bandwidth is listed as system dependent, meaning results will vary with the host platform's memory configuration.

The 820M wins in power efficiency and physical footprint. Its TDP is 15 W, compared to 170 W for the RX 7650 GRE. The 820M is an IGP with no power connectors, while the RX 7650 GRE requires a single 8-pin connector and a suggested power supply of 450 W. The 820M is built on a 4 nm process at TSMC, while the RX 7650 GRE uses a 6 nm process. The smaller node gives the 820M a transistor density advantage in principle, though transistor counts for the 820M are unknown. The RX 7650 GRE has 13,300 million transistors on a 204 mm² die, with a density of 65.2M per mm².

The RX 7650 GRE also wins on clock stability expectations. Its base clock is 1720 MHz and its game clock is 2350 MHz, with a boost of 2695 MHz. The 820M has a 400 MHz base and a 2800 MHz boost. The difference between base and boost on the 820M is substantial, which suggests the IGP will spend most of its time near the lower clock when power or thermal limits are reached. The RX 7650 GRE's game clock provides a consistent performance target for sustained workloads.

Display output is another differentiator. The RX 7650 GRE offers 1x HDMI 2.1a and 3x DisplayPort 2.1 connectors. The 820M's display outputs are portable device dependent, which means no fixed set of connectors. For multi-monitor setups or fixed desktop configurations, the RX 7650 GRE is the only one with a defined output configuration.

The Verdict

The data indicates that the RX 7650 GRE is the superior performer in absolute terms. Its 83rd percentile rank versus the 820M's 50th percentile makes the hierarchy clear. Any workload that stresses GPU compute, rendering, or memory bandwidth will favor the RX 7650 GRE. The 3DMark Steel Nomad score of 2336 and Geekbench OpenCL score of 83109 provide concrete evidence of its capability. The 820M has no recorded benchmark scores in the database, so its real-world performance cannot be quantified from the available data.

The RX 7650 GRE sits within 1.3% of the NVIDIA GeForce RTX 4070 SUPER, the NVIDIA Quadro M6000 24 GB, the NVIDIA GeForce RTX 5050 Mobile, and the NVIDIA Quadro M6000 in aggregate scoring. This places it in competitive territory among mid-range to high-end cards. The launch MSRP for the RX 7650 GRE is 279 USD.

The 820M is best suited for portable devices where the 15 W power envelope and IGP form factor are mandatory. Its 4 nm process node and RDNA 3.5 architecture give it modern feature support, including DirectX 12 Ultimate and Vulkan 1.4. The 2 ray tracing cores provide entry-level RT capability, though the 716.8 GFLOPS FP32 throughput will limit its utility in demanding titles. For a system that needs basic graphics acceleration with minimal power draw, the 820M fits that role. For any serious gaming, rendering, or compute work, the RX 7650 GRE is the only viable choice from the recorded data.
