AMD Radeon 820M vs Intel Data Center GPU Max 1100 Comparison

Where Each One Wins

The AMD Radeon 820M and Intel Data Center GPU Max 1100 occupy entirely different segments of the GPU spectrum, and the recorded data confirms they have almost no overlap in intended use cases. The Radeon 820M is an integrated graphics processor (IGP) designed for portable devices, with its display outputs listed as "Portable Device Dependent." The Intel Data Center GPU Max 1100 is a dual-slot discrete accelerator with no display outputs at all, indicating it is built exclusively for compute workloads in server environments.

The Radeon 820M wins in power efficiency and integration. Its 15 W TDP allows it to operate within the thermal envelope of a mobile processor, and its PCIe 4.0 x8 interface suits a laptop or compact system. The Intel part, by contrast, draws 300 W and requires a 700 W suggested power supply plus a single 12-pin power connector. This makes the Intel GPU suitable only for systems with substantial power delivery infrastructure.

The Intel Data Center GPU Max 1100 wins decisively in raw compute throughput. Its FP32 performance of 22.22 TFLOPS is approximately 31 times higher than the Radeon 820M's 716.8 GFLOPS. The Intel GPU also provides 48 GB of HBM2e memory with 1.23 TB/s bandwidth, whereas the AMD IGP relies on system-shared memory with bandwidth described as "System Dependent." For memory-intensive data center tasks, the Intel accelerator holds a clear advantage.

The Radeon 820M supports DirectX 12 Ultimate (12_2) and Vulkan 1.4, while the Intel GPU only reaches DirectX 12 (12_1) and has no Vulkan support listed. This gives the AMD part an edge in modern gaming API compatibility, though its 128 shading units and 4 ROPs limit its practical gaming performance. The Intel GPU has 7168 shading units and 56 ray tracing cores, but its 0 MPixel/s pixel rate indicates it is not optimized for rasterization output.

Specification Differences

The two GPUs differ across nearly every recorded specification. The Radeon 820M uses a 4 nm process node from TSMC, while the Intel Data Center GPU Max 1100 uses Intel's 10 nm process. The Intel GPU is built on a massive 1280 mm² die containing 100,000 million transistors, with a transistor density of 78.1M per mm². The AMD IGP's transistor count and die size are recorded as unknown.

Clock speeds show a notable difference in approach. The AMD part has a base clock of 400 MHz and a boost clock of 2800 MHz, indicating a wide dynamic range for power management. The Intel GPU runs at a base of 1000 MHz and boosts to 1550 MHz, with memory clocked at 600 MHz (1200 Mbps effective). The Radeon 820M's memory clock is listed as "System Shared."

Memory specifications are fundamentally different. The Intel GPU provides 48 GB of HBM2e on an 8192-bit bus with 1.23 TB/s bandwidth. The AMD IGP uses system-shared memory with no dedicated size, type, or bus width. This reflects the integrated nature of the Radeon part versus the discrete, high-capacity memory pool of the Intel accelerator.

The shading units differ by a factor of 56: the Intel GPU has 7168, while the Radeon 820M has 128. Texture mapping units are 448 versus 8, and ray tracing cores are 56 versus 2. The Intel GPU has 0 ROPs and a pixel rate of 0 MPixel/s, while the AMD part has 4 ROPs and a pixel rate of 11.20 GPixel/s. Texture rates are 694.4 GTexel/s for Intel versus 22.40 GTexel/s for AMD.

Form factor and power delivery are also distinct. The Radeon 820M is an IGP with no slot width, no power connectors, and no dimensions listed. The Intel GPU is dual-slot, 267 mm (10.5 inches) long, requires a 12-pin connector, and has a 300 W TDP. Bus interfaces differ as well: PCIe 4.0 x8 for AMD versus PCIe 5.0 x16 for Intel.

Architecture Differences

The Radeon 820M is built on RDNA 3.5 architecture, part of the Navi III IGP generation for Strix Point Mobile. Its chip is designated Krackan Point 2. The Intel Data Center GPU Max 1100 uses Generation 12.5 architecture on the Ponte Vecchio chip, classified under Data Center GPU (Ponte Vecchio). These are architecturally unrelated designs targeting different workloads.

The AMD part's FP16 performance matches its FP32 at 716.8 GFLOPS with a 1:1 ratio, indicating no dedicated half-precision acceleration. The Intel GPU also shows a 1:1 FP16-to-FP32 ratio, with both at 22.22 TFLOPS. Neither part lists tensor cores, though the Intel GPU's architecture is designed for data center compute.

The Intel GPU has 56 ray tracing cores, while the Radeon 820M has 2. However, the Intel part's pixel rate of 0 MPixel/s suggests its ray tracing hardware is not paired with traditional rasterization output stages. The AMD IGP, with 4 ROPs and 11.20 GPixel/s, at least provides basic pixel output for display purposes.

API support differs in important ways. The Radeon 820M supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The Intel GPU supports DirectX 12 (12_1) and OpenGL 4.6, but Vulkan support is not listed. For compute-focused deployments, the Intel GPU's lack of Vulkan may be less relevant, but the AMD part's newer DirectX feature level is notable.

The release dates are separated by roughly two years: the Intel GPU launched on January 9, 2023, while the Radeon 820M launched on February 28, 2025. The Intel part has a successor listed as H3C Graphics, while the AMD IGP's predecessor is Navi II IGP. Both are currently marked as Active in production status.

Head-to-Head Benchmarks

The recorded data includes no direct head-to-head benchmark scores, and both GPUs have zero wins in the head-to-head comparison table. The average benchmark score for both is 0, and their percentile versus all GPUs is 50 for each. This places both in the middle of the distribution, though the lack of actual benchmark entries means these figures carry limited interpretive weight.

The largest performance gap appears in FP32 throughput. The Intel Data Center GPU Max 1100's 22.22 TFLOPS dwarfs the Radeon 820M's 716.8 GFLOPS, a difference of approximately 31x. This translates directly to compute-bound workloads such as scientific simulation, AI inference, and data processing, where the Intel accelerator's 7168 shading units and 448 TMUs provide massive parallel throughput.

Texture rate follows a similar pattern. The Intel GPU's 694.4 GTexel/s is roughly 31 times higher than the AMD part's 22.40 GTexel/s. This indicates the Intel GPU can sustain far higher texture fetch and filtering rates, which matters for certain graphics and compute kernels that rely heavily on texture sampling.

The pixel rate tells the opposite story. The AMD Radeon 820M achieves 11.20 GPixel/s, while the Intel Data Center GPU Max 1100 records 0 MPixel/s. This suggests the Intel GPU lacks functional raster output stages, making it unsuitable for traditional display rendering. The AMD IGP, despite its low absolute performance, can at least produce pixel output for integrated display purposes.

Memory bandwidth shows an enormous divide. The Intel GPU's 1.23 TB/s over an 8192-bit HBM2e interface is matched against the AMD part's system-shared memory with unspecified bandwidth. For workloads that stream large datasets, the Intel accelerator's dedicated memory pool provides a structural advantage that the AMD IGP cannot match, since it must share system memory bandwidth with the CPU.

Ray tracing resources also differ substantially. The Intel GPU has 56 ray tracing cores versus 2 on the AMD part. However, the Intel GPU's 0 MPixel/s output suggests its ray tracing capability is intended for compute-style ray tracing rather than real-time rendering with display output. The AMD IGP's 2 ray tracing cores align with its DirectX 12 Ultimate support, which includes ray tracing features for gaming.

The clock behavior reveals different design philosophies. The AMD Radeon 820M spans from 400 MHz base to 2800 MHz boost, a 7x range that allows aggressive power saving at idle and higher performance when needed. The Intel Data Center GPU Max 1100 runs from 1000 MHz to 1550 MHz, a narrower range consistent with a constantly loaded server accelerator that prioritizes sustained throughput over burst capability.

Bus interface differences reinforce the positioning. The Intel GPU uses PCIe 5.0 x16, providing high bandwidth for host communication in data center servers. The AMD IGP uses PCIe 4.0 x8, which is appropriate for a mobile IGP but limits host-side data transfer compared to the Intel part's wider, faster interface.

The process node advantage belongs to AMD at 4 nm versus Intel's 10 nm, yet the Intel GPU compensates with a massive 1280 mm² die and 100,000 million transistors. The transistor density of 78.1M per mm² shows how Intel packed enormous compute resources into the Ponte Vecchio design, while the Radeon 820M's transistor count remains undisclosed.

Power efficiency favors the AMD part decisively. At 15 W TDP, the Radeon 820M delivers 716.8 GFLOPS, yielding roughly 47.8 GFLOPS per watt. The Intel GPU at 300 W delivers 22.22 TFLOPS, yielding approximately 74.1 GFLOPS per watt. The Intel part is actually more efficient per watt, though its absolute power draw makes it unsuitable for mobile use.

The Intel Data Center GPU Max 1100's 48 GB memory capacity and 8192-bit bus represent a server-class memory subsystem. The AMD Radeon 820M's system-shared memory approach means its effective bandwidth depends entirely on the host platform's memory configuration, making its performance highly variable across different systems.
