AMD Radeon 820M vs Intel Arc A380E x2 Comparison

Head-to-Head Benchmarks

The database contains no recorded benchmark scores for either the AMD Radeon 820M or the Intel Arc A380E x2. Both entries show an average benchmark score of zero, and the head-to-head comparison field is empty. Consequently, there are no numerical wins to report for either side in direct competition. The absence of measured data means that any performance ranking between these two parts cannot be established from the recorded information. Both GPUs sit at the 50th percentile against all GPUs in the database, a percentile that reflects their shared lack of scored benchmarks rather than any measured performance equivalence. Without benchmark entries, the analysis must rely on architectural specifications and feature comparisons to differentiate the two products.

FAQ

The Verdict

The recorded data does not support a performance verdict, as neither GPU has any benchmark scores in the database. The AMD Radeon 820M belongs to the RDNA 3.5 architecture on a 4 nm TSMC process, built for integrated use with a 15 W TDP and system shared memory. The Intel Arc A380E x2 is a discrete, single-slot card on the Xe-HPG architecture, fabricated on a 6 nm TSMC process, consuming 130 W with 6 GB of dedicated GDDR6 memory. The Intel card offers a substantially larger compute configuration: 1024 shading units, 64 TMUs, 32 ROPs, 8 ray tracing cores, 4.096 TFLOPS FP32, and 186.0 GB/s memory bandwidth. The AMD part presents 128 shading units, 8 TMUs, 4 ROPs, 2 ray tracing cores, 716.8 GFLOPS FP32, and system dependent bandwidth. The Intel Arc A380E x2 also has a higher pixel rate at 64.00 GPixel/s versus 11.20 GPixel/s, and a higher texture rate at 128.0 GTexel/s versus 22.40 GTexel/s. The AMD Radeon 820M counters with a higher boost clock of 2800 MHz versus 2000 MHz, a smaller process node of 4 nm versus 6 nm, and a far lower power draw of 15 W versus 130 W. The Radeon 820M also offers FP16 at a 1:1 ratio with FP32 at 716.8 GFLOPS, whereas the Intel part delivers FP16 at 8.192 TFLOPS with a 2:1 ratio. The choice between these two hinges on the use case: the AMD IGP suits low-power integrated systems, while the Intel discrete card suits installations requiring dedicated memory and higher throughput.

Specification Differences

The two GPUs differ across nearly every measured specification. The AMD Radeon 820M uses the Krackan Point 2 chip with RDNA 3.5 architecture, while the Intel Arc A380E x2 uses the DG2-128 chip with Xe-HPG architecture. The process nodes differ: 4 nm for AMD, 6 nm for Intel, both from TSMC. The Intel part has known transistor counts and die size: 7,200 million transistors on a 157 mm² die with a density of 45.9M per mm². The AMD part lists these as unknown. Clock speeds show the AMD part at 400 MHz base and 2800 MHz boost, while the Intel part runs at 2000 MHz base and 2000 MHz boost. Memory configurations are entirely different: the AMD Radeon 820M uses system shared memory with system dependent bandwidth, while the Intel Arc A380E x2 has 6 GB GDDR6, a 96-bit bus, and 186.0 GB/s bandwidth. Compute resources favor Intel: 1024 shading units, 64 TMUs, 32 ROPs, and 8 ray tracing cores versus 128 shading units, 8 TMUs, 4 ROPs, and 2 ray tracing cores. The Intel card achieves 64.00 GPixel/s pixel rate and 128.0 GTexel/s texture rate, compared to 11.20 GPixel/s and 22.40 GTexel/s on the AMD part. FP32 performance is 4.096 TFLOPS for Intel versus 716.8 GFLOPS for AMD. FP16 performance is 8.192 TFLOPS for Intel versus 716.8 GFLOPS for AMD. The Intel card draws 130 W with a 6-pin connector and a 300 W suggested PSU, while the AMD IGP draws 15 W with no connectors. The Intel card is a single-slot design measuring 265 mm by 127 mm by 20 mm, while the AMD part is an IGP with no listed dimensions. Display outputs also differ: the Intel card provides 8x mini-DisplayPort 2.0, while the AMD part's outputs are portable device dependent. The Intel card is End-of-life with Battlemage as successor; the AMD part is Active with no successor listed.

Architecture Differences

The architectural divide is significant. The AMD Radeon 820M is built on RDNA 3.5, part of the Navi III IGP generation for Strix Point Mobile, fabricated on TSMC's 4 nm process. The Intel Arc A380E x2 is built on Xe-HPG, part of the Alchemist generation for Arc 3, fabricated on TSMC's 6 nm process. The AMD chip integrates graphics into the processor package as an IGP with no slot width and no power connectors, while the Intel chip is a discrete single-slot card with a 6-pin power connector. The Intel architecture provides 8 ray tracing cores and a 2:1 FP16 to FP32 ratio, allowing 8.192 TFLOPS FP16 from 4.096 TFLOPS FP32. The AMD architecture provides a 1:1 FP16 to FP32 ratio, holding both at 716.8 GFLOPS. The AMD part has 2 ray tracing cores. Memory architecture differs fundamentally: the AMD IGP relies on system shared memory with bandwidth dependent on the host system, while the Intel card has dedicated GDDR6 on a 96-bit bus with fixed 186.0 GB/s bandwidth. The Intel card also has a known transistor count of 7,200 million on a 157 mm² die, while the AMD part's transistor count and die size are unknown. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Both use a PCIe 4.0 x8 bus interface. The Intel card has 8x mini-DisplayPort 2.0 outputs, while the AMD IGP's display outputs depend on the portable device it is integrated into. The Intel part's predecessor is Xe Graphics and its successor is Battlemage. The AMD part's predecessor is Navi II IGP, with no successor listed. Production status differs: the AMD part is Active, the Intel part is End-of-life.

Where Each One Wins

The AMD Radeon 820M wins in power efficiency and integration. Its 15 W TDP, lack of power connectors, and IGP form factor make it suited for portable devices where space and cooling are constrained. It also holds a process node advantage at 4 nm versus 6 nm, and a higher boost clock at 2800 MHz versus 2000 MHz. Its system shared memory approach means no dedicated VRAM allocation is needed, which can be flexible in unified memory architectures. The AMD part is Active in production and newer, released on 2025-02-28.

The Intel Arc A380E x2 wins in raw compute and memory resources. Its 1024 shading units, 64 TMUs, 32 ROPs, and 8 ray tracing cores provide a much larger execution footprint. Its dedicated 6 GB GDDR6 memory with 186.0 GB/s bandwidth removes dependence on system memory performance. The Intel card delivers 4.096 TFLOPS FP32, 8.192 TFLOPS FP16, 64.00 GPixel/s pixel rate, and 128.0 GTexel/s texture rate. It also provides 8x mini-DisplayPort 2.0 outputs, supporting multi-display configurations directly from the card. Its 130 W TDP and 300 W suggested PSU indicate a system with dedicated power delivery. The Intel card is End-of-life, with Battlemage as its successor, while the AMD IGP remains Active.

The data shows a clear separation: the AMD Radeon 820M suits low-power integrated platforms, while the Intel Arc A380E x2 suits workloads requiring dedicated memory, higher throughput, and multi-display output. No benchmark scores exist to confirm actual application performance differences, so the recorded specifications serve as the only basis for differentiation.
