AMD Radeon 820M vs AMD Radeon AI PRO 9600D Comparison

Where Each One Wins

The AMD Radeon 820M and AMD Radeon AI PRO 9600D occupy entirely different segments of the GPU spectrum, and the benchmark data reflects that divide clearly. The Radeon 820M is an integrated graphics processor built for thin-and-light mobile systems, while the Radeon AI PRO 9600D is a discrete workstation card designed for professional compute and rendering workloads.

The Radeon 820M wins in power efficiency and integration. Its 15 W TDP allows it to operate without any power connectors, making it suitable for portable devices where space and thermal headroom are limited. It draws power from the system memory, which is shared dynamically with the CPU. This makes it a practical choice for basic display output, light media playback, and casual workloads that do not demand sustained GPU throughput.

The Radeon AI PRO 9600D wins in virtually every raw performance category. It uses a dedicated 32 GB GDDR6 memory pool over a 256 bit bus, delivering 576.0 GB/s of bandwidth. The 820M has no dedicated VRAM, relying instead on system memory with bandwidth that is system dependent. The discrete card also brings 3072 shading units, 192 texture mapping units, and 96 render output units, compared to 128 shading units, 8 TMUs, and 4 ROPs on the integrated part. The performance gap is enormous, and the AI PRO 9600D is clearly aimed at tasks that require large datasets and heavy parallel computation.

Architecture Differences

The two GPUs come from different architecture generations. The Radeon 820M uses RDNA 3.5, built on a 4 nm TSMC process, and belongs to the Navi III IGP (Strix Point Mobile) generation. Its chip is called Krackan Point 2. The Radeon AI PRO 9600D uses RDNA 4.0, also on a 4 nm TSMC process, but belongs to the Radeon Pro Navi (Navi IV Series) generation with a Navi 48 chip.

The transistor counts differ wildly. The AI PRO 9600D packs 53,900 million transistors on a 357 mm² die, giving it a transistor density of 151.0M per mm². The 820M's transistor count and die size are listed as unknown in the database, but the scale of the difference is clear from the shading unit counts and memory subsystem. The discrete card has 24 times the shading units of the integrated GPU.

Ray tracing hardware also differs. The 820M includes 2 ray tracing cores, while the AI PRO 9600D includes 48, a 24-fold increase. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API feature coverage is identical. The bus interface differs as well: the 820M uses PCIe 4.0 x8, while the AI PRO 9600D uses PCIe 5.0 x16, doubling the available bandwidth per lane and quadrupling the lane count.

Clock behavior is another differentiator. The 820M has a base clock of 400 MHz and a boost clock of 2800 MHz. The AI PRO 9600D has a higher base clock of 1080 MHz but a lower boost clock of 2020 MHz. The integrated part boosts aggressively when power and thermals allow, while the discrete card maintains a more moderate boost profile to stay within its 150 W TDP envelope.

Head-to-Head Benchmarks

The database does not contain direct head-to-head benchmark scores for these two GPUs, and neither has recorded benchmark entries or average scores. The percentile field for both is 50, indicating they sit at the median of all GPUs in the database's historical distribution. The wins counter shows 0 for both sides, reflecting the absence of matched testing data.

Despite the lack of direct measurements, the specification data allows for meaningful comparison of theoretical peak throughput. The AI PRO 9600D delivers 24.82 TFLOPS of FP32 compute, while the 820M delivers 716.8 GFLOPS. That is a 34.6-fold difference in raw floating-point throughput. The texture rate shows a similarly large gap: 387.8 GTexel/s versus 22.40 GTexel/s, a 17.3-fold difference. Pixel rate is 193.9 GPixel/s versus 11.20 GPixel/s, a 17.3-fold difference as well.

Memory bandwidth is perhaps the most consequential gap for real-world workloads. The AI PRO 9600D moves data at 576.0 GB/s over its 256 bit GDDR6 interface. The 820M's bandwidth is listed as system dependent, meaning it shares the CPU's memory controller and is subject to platform limitations. In practice, integrated graphics typically achieve only a fraction of dedicated GDDR6 bandwidth, and the discrete card's dedicated memory avoids contention with CPU workloads entirely.

The AI PRO 9600D's ray tracing capability is also 24 times higher in core count, which translates directly to ray tracing throughput in supported applications. The 820M's 2 ray tracing cores are sufficient for basic effects but will struggle with complex scenes. The discrete card's 48 cores are designed for professional visualization and rendering tasks that rely heavily on ray-traced lighting and shadows.

The Verdict

The data points to a simple conclusion: these two GPUs serve completely different markets. The Radeon 820M is an integrated solution for portable devices where 15 W power draw and the absence of power connectors are essential. It delivers 716.8 GFLOPS of FP32 compute, 22.40 GTexel/s texture throughput, and 11.20 GPixel/s pixel fill, which is adequate for basic display tasks and light media workloads. Its 2 ray tracing cores and shared memory architecture place it firmly in the entry-level segment.

The Radeon AI PRO 9600D is a professional discrete GPU with 32 GB of dedicated GDDR6 memory, 24.82 TFLOPS of FP32 compute, 387.8 GTexel/s texture throughput, and 193.9 GPixel/s pixel fill. Its 48 ray tracing cores, single-slot form factor, and PCIe 5.0 x16 interface target workstation environments. The 150 W TDP and 450 W suggested PSU indicate it is designed for desktop systems with adequate power delivery.

Users who need a GPU for a thin laptop or compact portable device should use the Radeon 820M, as its system shared memory and low power draw are the only viable option in that form factor. Users who need dedicated graphics memory, high compute throughput, and professional ray tracing performance should use the Radeon AI PRO 9600D. The 34.6-fold gap in FP32 performance and the 24-fold gap in ray tracing cores leave no ambiguity about which GPU is faster, but the 820M is not trying to compete on that basis. It exists to provide basic graphics capability in power-constrained devices, while the AI PRO 9600D exists to handle demanding professional workloads.
