Architecture Differences

The AMD Radeon RX 7800 XT and Intel Graphics 24EU Mobile represent opposite ends of the GPU spectrum. The AMD card uses the Navi 32 chip with the RDNA 3.0 architecture, fabricated on a 5 nm TSMC process. It integrates 28,100 million transistors on a 346 mm² die, achieving a transistor density of 81.2M per mm². The Intel part uses the Twin Lake chip with the Xe-LP architecture on a 10 nm Intel process, with transistor count and die size listed as unknown.

The compute resources differ dramatically. The AMD Radeon RX 7800 XT contains 3,840 shading units, 240 texture mapping units (TMUs), 96 raster output units (ROPs), and 60 ray tracing cores. The Intel Graphics 24EU Mobile contains 192 shading units, 12 TMUs, and 4 ROPs, with no ray tracing cores listed. This 20x difference in shading units and 20x difference in TMUs establishes the performance ceiling for each product.

Clock behavior also diverges. The AMD card runs at a 1295 MHz base clock, 2124 MHz game clock, and 2430 MHz boost clock, with memory clocked at 2438 MHz delivering 19.5 Gbps effective. The Intel IGP runs at a 300 MHz base and 1000 MHz boost, with system shared memory. The AMD card's boost clock is more than double the Intel part's boost clock.

The AMD Radeon RX 7800 XT is a dual-slot card measuring 267 mm in length, 111 mm in height, and 50 mm in width, requiring PCIe 4.0 x16 interface and 2x 8-pin power connectors. The Intel Graphics 24EU Mobile is an IGP with no physical dimensions listed, using a Ring Bus interface and drawing power directly from the motherboard.

Display output capabilities reflect their target platforms. The AMD card provides 1x HDMI 2.1a and 3x DisplayPort 2.1 outputs. The Intel IGP's display outputs are listed as Portable Device Dependent, indicating it serves mobile and compact systems.

The AMD Radeon RX 7800 XT supports DirectX 12 Ultimate (12_2), which includes hardware ray tracing and mesh shaders. The Intel Graphics 24EU Mobile supports DirectX 12 (12_1), a lower feature level without those advanced capabilities.

The Verdict

The benchmark database shows the AMD Radeon RX 7800 XT as a high-performance discrete desktop graphics card, while the Intel Graphics 24EU Mobile is an entry-level integrated solution. The recorded data indicates the AMD card achieves 37.32 TFLOPS FP32, 37.32 TFLOPS FP16 (1:1), a pixel rate of 233.3 GPixel/s, and a texture rate of 583.2 GTexel/s. The Intel part delivers 384.0 GFLOPS FP32 and 768.0 GFLOPS FP16 (2:1), with a 4.000 GPixel/s pixel rate and 12.00 GTexel/s texture rate.

The AMD Radeon RX 7800 XT carries an average benchmark score of 11627 and ranks in the 51st percentile of all GPUs. It has nearest rivals including the NVIDIA GeForce GTX 1660 (average score 11680, delta -0.5%), AMD Radeon Pro 5500M (11528, delta +0.9%), NVIDIA Tesla K20c (11479, delta +1.3%), and AMD Radeon RX 6500 XT (11842, delta -1.8%). These rivals are all within roughly 2% of the AMD card's average score, indicating it sits in a competitive mid-range tier.

The Intel Graphics 24EU Mobile has no benchmark scores recorded, no average benchmark score, and no nearest rivals in the database. Its 50th percentile ranking appears alongside zero measured performance data.

The AMD Radeon RX 7800 XT is appropriate for desktop systems requiring substantial graphics throughput, 16 GB of dedicated GDDR6 memory, and full DirectX 12 Ultimate support. The Intel Graphics 24EU Mobile is suited for portable devices where the 6 W power draw and integrated form factor take priority over raw performance. The data shows no overlap in their performance envelopes, as the AMD card's FP32 throughput is roughly 97 times higher than the Intel part's.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries between the AMD Radeon RX 7800 XT and the Intel Graphics 24EU Mobile. However, the available benchmark suite for the AMD card provides context for its performance position.

The AMD Radeon RX 7800 XT scores 4157 in 3DMark Steel Nomad DX12. In Geekbench, it achieves 18290 in OpenCL and 54228 in Vulkan. The PassMark suite shows 121 in DirectX 10, 249 in DirectX 11, 93 in DirectX 12, 304 in DirectX 9, 1177 in G2D, 24176 in G3D, and 13473 in GPU Compute. Its average benchmark score is 11627.

The Intel Graphics 24EU Mobile has no recorded benchmark scores in any test. The database lists zero results for this part, making direct numeric comparison impossible. What the data does show is the AMD card's relative standing among its nearest rivals: the NVIDIA GeForce GTX 1660 scores 11680 on average, just 0.5% above the RX 7800 XT; the AMD Radeon Pro 5500M scores 11528, 0.9% below; the NVIDIA Tesla K20c scores 11479, 1.3% below; and the AMD Radeon RX 6500 XT scores 11842, 1.8% above.

The AMD card's individual benchmark results show its strongest showing in the PassMark G3D test at 24176, followed by Geekbench Vulkan at 54228. Its weakest PassMark result is DirectX 12 at 93, while DirectX 9 reaches 304. The spread between these results indicates the architecture's varying efficiency across different API workloads.

The performance gap between the two GPUs in this comparison is defined by their fundamental specifications rather than direct measurements. The AMD Radeon RX 7800 XT delivers 37.32 TFLOPS FP32 versus 384.0 GFLOPS for the Intel IGP, a 97.2x difference in raw compute throughput. Pixel rate differs by a similar magnitude: 233.3 GPixel/s versus 4.000 GPixel/s, a 58.3x gap. Texture rate shows a 48.6x difference at 583.2 GTexel/s versus 12.00 GTexel/s.

The AMD card's 16 GB of GDDR6 memory with 624.1 GB/s bandwidth provides dedicated graphics memory, while the Intel part relies on system shared memory with system dependent bandwidth. This memory architecture difference compounds the compute disparity, as the AMD card avoids the latency and contention of shared memory access.

The AMD Radeon RX 7800 XT also carries 60 ray tracing cores, enabling hardware-accelerated ray tracing workloads. The Intel Graphics 24EU Mobile lists no ray tracing cores, limiting it to rasterization workloads within its DirectX 12 (12_1) feature level. The AMD card's DirectX 12 Ultimate (12_2) support includes additional features not available on the Intel part.

For the Intel Graphics 24EU Mobile, the absence of benchmark data in the database means its 50th percentile ranking reflects its position among all GPUs without measured performance confirmation. The AMD Radeon RX 7800 XT's 51st percentile ranking is supported by its ten recorded benchmark scores across multiple test suites.
