Architecture Differences

The two GPUs represent different strata of AMD's product stack, and their architectural specifications reflect that separation. The Radeon 820M is a 4 nm IGP fabricated by TSMC, using the RDNA 3.5 architecture with the Krackan Point 2 chip. It belongs to the Navi III IGP generation for Strix Point Mobile platforms. The Radeon RX 9070 GRE is a discrete desktop part also on a 4 nm TSMC node, but it uses the newer RDNA 4.0 architecture with the Navi 48 chip from the Navi IV (RX 9000) series.

The transistor count and die size are unknown for the 820M, but the RX 9070 GRE contains 53,900 million transistors on a 357 mm² die, yielding a transistor density of 151.0M per mm². The 820M has no independent transistor or die size data recorded, which is typical for an integrated solution where the GPU shares the package with other components.

The execution resource counts differ by an order of magnitude. The 820M has 128 shading units, 8 texture mapping units, and 4 render output units. The RX 9070 GRE has 3072 shading units, 192 TMUs, and 96 ROPs. Both have ray tracing cores, with the 820M featuring 2 and the RX 9070 GRE featuring 48. Neither part lists tensor cores in the database.

Clock behavior also separates the two. The 820M has a base clock of 400 MHz and a boost clock of 2800 MHz, with no separate game clock. The RX 9070 GRE has a base clock of 1420 MHz, a game clock of 2220 MHz, and a boost clock of 2790 MHz. The memory clock for the 820M is System Shared, while the RX 9070 GRE runs its GDDR6 at 2250 MHz, which translates to 18 Gbps effective.

API support is identical across both cards: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The bus interfaces differ, with the IGP using PCIe 4.0 x8 and the discrete card using PCIe 5.0 x16. The 820M is an IGP slot width with no power connectors, while the RX 9070 GRE is dual-slot and requires two 8-pin connectors.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries for this pair, so the comparison relies on the recorded performance metrics and the nearest rival analysis for the RX 9070 GRE. The 820M has no benchmark scores listed and a percentile rank of 50 among all GPUs, while the RX 9070 GRE has a percentile rank of 87.

The RX 9070 GRE's recorded benchmarks show a 3DMark Steel Nomad DX12 score of 5424 and a Geekbench OpenCL score of 109309. Its average benchmark score is 57367. The 820M has an average benchmark score of 0, as no tests are recorded in the database.

The nearest rivals for the RX 9070 GRE provide context for its standing. The Intel Arc A580 has an average score of 57756, which is 0.7% higher than the RX 9070 GRE's average. The AMD Radeon RX 5600 OEM scores 58085, which is 1.2% higher. The Intel Arc A570M scores 58239, 1.5% higher. The AMD Radeon RX 6950 XT scores 58392, 1.8% higher. These deltas are all negative from the RX 9070 GRE's perspective, indicating the card sits slightly below each of these four rivals in average benchmark score.

The data shows that the RX 9070 GRE occupies a competitive position near the top of its peer group, with the closest rival, the Intel Arc A580, being less than one percentage point ahead. The RX 6950 XT, a previous-generation flagship, holds a 1.8% advantage, which is a modest gap given the generational difference.

In terms of pure throughput, the RX 9070 GRE massively outpaces the 820M. The discrete card delivers 34.28 TFLOPS of FP32 compute versus 716.8 GFLOPS for the IGP. The pixel rate for the RX 9070 GRE is 267.8 GPixel/s versus 11.20 GPixel/s for the 820M. The texture rate is 535.7 GTexel/s versus 22.40 GTexel/s. Each of these metrics shows the RX 9070 GRE holding a commanding lead of roughly 24 to 48 times depending on the specific operation.

Memory bandwidth tells a similar story. The RX 9070 GRE has 432.0 GB/s of dedicated bandwidth, while the 820M's bandwidth is System Dependent, meaning it relies on shared system memory. The 12 GB GDDR6 frame buffer on the RX 9070 GRE contrasts with the System Shared memory allocation of the IGP.

The Verdict

The benchmark data presents a clear separation between these two GPUs. The AMD Radeon 820M is an integrated graphics solution designed for portable devices, with a 15 W TDP, no power connectors, and system-shared memory. Its performance metrics are modest, with 716.8 GFLOPS of FP32 compute and a pixel rate of 11.20 GPixel/s. It ranks at the 50th percentile among all GPUs in the database, with no recorded benchmark scores.

The AMD Radeon RX 9070 GRE is a high-end discrete graphics card. It ranks at the 87th percentile, has an average benchmark score of 57367, and sits within 1.8% of four nearest rivals: the Intel Arc A580, AMD Radeon RX 5600 OEM, Intel Arc A570M, and AMD Radeon RX 6950 XT. Its 34.28 TFLOPS of FP32 compute, 432.0 GB/s of memory bandwidth, and 12 GB GDDR6 frame buffer place it in a different performance class entirely.

The data indicates that the RX 9070 GRE is the appropriate choice for demanding 3D workloads, high-resolution gaming, or any application requiring substantial compute throughput and dedicated video memory. Its 220 W TDP and dual 8-pin power connector requirement are consistent with its performance tier.

The Radeon 820M serves the ultra-mobile segment where power efficiency is paramount. Its 15 W TDP and integrated design make it suitable for thin-and-light laptops where discrete graphics are not feasible. Its performance is sufficient for basic graphics tasks, and its System Dependent memory bandwidth reflects its role as a shared-resource IGP.

The recorded data shows no benchmark overlap between the two. The RX 9070 GRE's nearest rivals are all within a narrow 1.8% band, indicating a tight competitive cluster at its performance level. The 820M has no rivals listed in the database, reflecting its unique position as a low-power integrated solution. The verdict from the data is straightforward: the RX 9070 GRE delivers roughly 48 times the FP32 throughput of the 820M, and the two are not competing for the same use cases.
