AMD Radeon 820M vs AMD Radeon RX 7600M XT Comparison

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries for the AMD Radeon 820M versus the AMD Radeon RX 7600M XT. The 820M has no recorded benchmark scores, while the RX 7600M XT carries a full suite of results. This absence of overlapping data means direct score comparisons are impossible. However, the RX 7600M XT’s individual results provide a clear reference point for its performance class.

Focusing on the RX 7600M XT, its strongest recorded result comes from Geekbench OpenCL, where it scores 74869 points. The 3DMark Steel Nomad DX12 test yields 2048 points, while Geekbench Vulkan returns 27793 points. In Passmark testing, the GPU delivers a G3D score of 13907, a G2D score of 894, and a GPU compute score of 7140. The legacy DirectX tests show 175 in DX9, 137 in DX11, 76 in DX10, and 58 in DX12. These figures indicate a wide performance spread across different workloads, with OpenCL and compute-heavy tasks producing the highest raw numbers.

The RX 7600M XT’s average benchmark score sits at 12710 points. Its nearest rivals in the database are the NVIDIA GeForce GTX 670 with an average score of 12773 and a delta of -0.5%, the AMD Radeon Pro 455 with 12831 points and a delta of -0.9%, the NVIDIA GeForce GTX 590 with 12830 points and a delta of -0.9%, and the NVIDIA Tesla K20Xm with 12625 points and a delta of 0.7%. This places the RX 7600M XT within a tight cluster, trailing the GTX 670 and GTX 590 by less than one percent, while leading the Tesla K20Xm by 0.7%. The percentile ranking of 52 indicates the RX 7600M XT sits slightly above the median of all GPUs in the database.

For the 820M, the absence of benchmark scores and a zero average score means the database records no measurable performance data. Its percentile ranking of 50, however, places it at the midpoint of all GPUs, which suggests a baseline position without confirmed results. The head-to-head wins tally shows zero wins for both parts, reflecting the lack of direct comparison data rather than any competitive outcome.

Where Each One Wins

Without shared benchmarks, the win condition falls to architectural capability and memory configuration. The RX 7600M XT commands a decisive advantage in raw compute resources. It packs 2048 shading units, 128 texture mapping units, 64 render output units, and 32 ray tracing cores. The 820M, by contrast, offers 128 shading units, 8 TMUs, 4 ROPs, and 2 ray tracing cores. These are 16x, 16x, 16x, and 16x differences respectively, which translate into massive throughput gaps in every rasterization and ray tracing workload.

Memory bandwidth further separates the two. The RX 7600M XT uses 8 GB of GDDR6 memory on a 128-bit bus, delivering 288.0 GB/s of bandwidth. The 820M relies on system shared memory, with bandwidth described as system dependent. This means the 820M’s memory performance is entirely contingent on the host laptop’s RAM configuration, which cannot match dedicated GDDR6 in most scenarios. The RX 7600M XT’s pixel rate of 158.0 GPixel/s and texture rate of 316.0 GTexel/s dwarf the 820M’s 11.20 GPixel/s and 22.40 GTexel/s.

The RX 7600M XT also leads in floating-point throughput. Its FP32 performance reaches 20.23 TFLOPS, while its FP16 performance hits 40.45 TFLOPS with a 2:1 ratio. The 820M manages 716.8 GFLOPS for both FP32 and FP16, running at a 1:1 ratio. This gives the RX 7600M XT over 28 times the FP32 compute and over 56 times the FP16 compute. For gaming, content creation, or any GPU-accelerated task, the RX 7600M XT is categorically superior.

The 820M does hold advantages in power efficiency and integration. Its TDP of 15 W is eight times lower than the RX 7600M XT’s 120 W. The 820M operates as an IGP with no power connectors, making it suitable for thin-and-light laptops where battery life and thermals take priority. The RX 7600M XT, despite also being listed as IGP slot width and having no power connectors, draws substantially more power and requires a larger thermal solution. The 820M also uses a more advanced 4 nm process node from TSMC, versus the 6 nm node of the RX 7600M XT, which contributes to its efficiency profile.

Architecture Differences

The two GPUs belong to different RDNA generations. The 820M uses RDNA 3.5 architecture, while the RX 7600M XT uses RDNA 3.0. This generational gap influences feature support and efficiency. The 820M is part of the Navi III IGP generation for Strix Point Mobile, built on the Krackan Point 2 chip. The RX 7600M XT belongs to the Navi Mobile generation under the RX 7000M series, using the Navi 33 chip with the codename Hotpink Bonefish.

The manufacturing process differs significantly. The 820M is fabricated on TSMC’s 4 nm process, whereas the RX 7600M XT uses TSMC’s 6 nm process. The RX 7600M XT has a known die size of 204 mm² and a transistor count of 13,300 million, yielding a transistor density of 65.2M per mm². The 820M’s transistor count and die size are listed as unknown, so no density comparison is possible.

Clock speeds show contrasting strategies. The 820M has a base clock of 400 MHz and a boost clock of 2800 MHz, indicating a design that ramps aggressively under load. The RX 7600M XT operates with a base clock of 1280 MHz, a boost clock of 2469 MHz, and a game clock of 2023 MHz. The 820M’s higher boost clock reflects its smaller shader count, allowing each unit to run faster while maintaining a 15 W envelope. The RX 7600M XT’s memory clock runs at 2250 MHz with 18 Gbps effective speed, while the 820M’s memory clock is system shared.

Both GPUs support identical API levels: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The bus interface differs, with the 820M using PCIe 4.0 x8 and the RX 7600M XT using PCIe 4.0 x16. This doubles the bandwidth available to the discrete GPU for data transfer, which matters when streaming textures or compute workloads. The RX 7600M XT’s predecessor is listed as Polaris Mobile, while the 820M’s predecessor is Navi II IGP. Both are currently in active production status. The RX 7600M XT was released on January 3, 2023, while the 820M’s release date is February 28, 2025.

The Verdict

The recorded data shows a clear hierarchy. The RX 7600M XT is a high-performance mobile discrete GPU intended for gaming and demanding compute tasks. Its 2048 shading units, 8 GB of GDDR6 memory, and 20.23 TFLOPS FP32 performance place it in a different performance tier than the 820M. The benchmark suite confirms its capability, with a Passmark G3D score of 13907 and a Geekbench OpenCL score of 74869. The average benchmark score of 12710 and a percentile ranking of 52 position it just above the midpoint of all GPUs, with nearest rivals in the GTX 670 and GTX 590 class.

The 820M, with no recorded benchmarks, cannot be quantitatively compared. Its 128 shading units and 716.8 GFLOPS FP32 performance, combined with system shared memory, point to a design optimized for basic graphics acceleration in ultraportable laptops. Its 15 W TDP and 4 nm process make it an efficiency-focused part, but the raw performance gap to the RX 7600M XT is enormous, estimated at over 28 times in FP32 throughput based on the architectural specifications.

Users requiring playable frame rates in modern titles, GPU-accelerated rendering, or any compute-heavy workload should select the RX 7600M XT. The data confirms it delivers competitive performance against its peers, trailing the GTX 670 by only 0.5% and leading the Tesla K20Xm by 0.7%. Users prioritizing battery life, portability, and minimal heat output should choose the 820M, which offers modern RDNA 3.5 features at a fraction of the power draw. The choice hinges entirely on whether performance or efficiency drives the purchase decision, as the two parts occupy opposite ends of the mobile GPU spectrum.
