AMD Instinct MI300A vs Intel UHD Graphics 770 Mobile Comparison

Where Each One Wins

The recorded data for these two parts shows no overlapping benchmark wins. AMD Instinct MI300A and Intel UHD Graphics 770 Mobile occupy entirely separate positions in the database, with zero head-to-head benchmark entries and zero wins recorded for either side. This is not a close competition; the two devices are built for fundamentally different workloads and market segments.

The AMD Instinct MI300A is a compute-oriented accelerator with a 50th percentile rank among all GPUs. It delivers 61.29 TFLOPS of FP32 throughput, which places it in a class of hardware designed for dense mathematical workloads. Its 128 GB of HBM3 memory with 5.32 TB/s of bandwidth indicates a part intended for large-scale data processing, scientific simulation, and AI training tasks. The absence of any display outputs and the lack of DirectX, OpenGL, or Vulkan API support confirms this is not a graphics-rendering product at all.

The Intel UHD Graphics 770 Mobile is an integrated graphics processor embedded within Raptor Lake mobile processors. It produces 819.2 GFLOPS of FP32 performance and 1.638 TFLOPS of FP16 with a 2:1 ratio. Its 256 shading units, 16 texture mapping units, and 8 raster operation units support traditional graphics rendering. The part supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4, and its display outputs are described as portable device dependent, meaning it handles screen output for laptops and mobile systems. The production status is listed as active, and its successor is Arc Graphics-M.

The data shows no scenario where these two parts compete for the same task. The MI300A has no pixel rate (0 MPixel/s), meaning it cannot rasterize images. The UHD 770 Mobile has a pixel rate of 12.80 GPixel/s, confirming it can. Conversely, the UHD 770 Mobile has no path to the memory capacity or bandwidth of the MI300A, as its memory is system shared and system dependent. Each part wins solely within its own domain, and the database records no crossover performance comparison.

Architecture Differences

The architectural gap between these two processors is substantial. The AMD Instinct MI300A uses the CDNA 3.0 architecture, built on a 5 nm process at TSMC. Its chip, codenamed Aqua Vanjaram, integrates 153,000 million transistors on a die measuring 1017 mm². That yields a transistor density of 150.4 million transistors per square millimeter. The base clock is 1000 MHz with a boost clock of 2100 MHz. Memory runs at 1300 MHz, which translates to 5.2 Gbps effective.

The Intel UHD Graphics 770 Mobile uses the Generation 12.2 architecture, built on a 10 nm process at Intel. The chip is Raptor Lake, part of the HD Graphics-M generation. The database does not list transistor count, die size, or transistor density for this part. Its base clock is 300 MHz with a boost clock of 1600 MHz. Memory is system shared, with the bus width, type, and bandwidth all listed as system dependent.

The compute resources differ by orders of magnitude. The MI300A has 14,592 shading units, 912 texture mapping units, and zero raster operation units. The UHD 770 Mobile has 256 shading units, 16 texture mapping units, and 8 raster operation units. Neither part lists tensor cores or ray tracing cores in the database.

The MI300A uses an OAM Module slot width, requires no power connectors, and suggests a 1150 W power supply. Its TDP is 750 W. The UHD 770 Mobile is an IGP with a TDP of 15 W and uses a Ring Bus interface. The MI300A connects via PCIe 5.0 x16. The UHD 770 has no separate power connector data and no suggested power supply.

The MI300A has no display outputs and no API support for DirectX, OpenGL, or Vulkan. The UHD 770 Mobile supports all three, with DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4. The MI300A produces a texture rate of 1,915.2 GTexel/s, while the UHD 770 produces 25.60 GTexel/s. The MI300A has no pixel rate; the UHD 770 has 12.80 GPixel/s.

Release dates differ by roughly eleven months. The MI300A launched on 2023-12-05, and the UHD 770 Mobile launched on 2023-01-03. The MI300A lists Radeon Instinct as its predecessor. The UHD 770 Mobile lists Arc Graphics-M as its successor and is currently marked as active in production.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries for these two parts. There are zero wins recorded for the AMD Instinct MI300A and zero wins recorded for the Intel UHD Graphics 770 Mobile. The average benchmark score for both parts is 0, and the percentile rank for both is 50 out of all GPUs.

Because no comparative benchmark data exists, the analysis must rely on the recorded specification differences to interpret relative capability. The FP32 compute figures illustrate the scale of the gap: 61.29 TFLOPS versus 819.2 GFLOPS. The MI300A delivers approximately 75 times the FP32 throughput of the UHD 770 Mobile. Texture rate shows a similar split: 1,915.2 GTexel/s versus 25.60 GTexel/s, a factor of roughly 75 as well.

Memory bandwidth presents an even wider divide. The MI300A provides 5.32 TB/s from 128 GB of HBM3 across an 8192-bit bus. The UHD 770 Mobile uses system shared memory with bandwidth described only as system dependent, so no direct numeric comparison is possible. The MI300A memory clock is 1300 MHz with 5.2 Gbps effective, while the UHD 770 has no dedicated memory clock listed beyond the system shared designation.

The UHD 770 Mobile holds advantages in areas the MI300A cannot address. It supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4. The MI300A lists N/A for all three APIs. The UHD 770 has a pixel rate of 12.80 GPixel/s, while the MI300A is 0 MPixel/s. The UHD 770 has 8 raster operation units; the MI300A has 0. The UHD 770 also has a lower TDP at 15 W compared to 750 W, and it can output to portable device dependent displays, whereas the MI300A has no outputs at all.

The FP16 figures also differentiate the parts. The UHD 770 Mobile lists 1.638 TFLOPS with a 2:1 ratio. The MI300A lists fp16 as null in the database, so no comparison can be made from recorded data.

The Verdict

The data supports a clear separation of roles. The AMD Instinct MI300A is a compute accelerator with no graphics output, no API support, and no pixel pipeline. Its 61.29 TFLOPS FP32 throughput, 128 GB of HBM3, and 5.32 TB/s bandwidth indicate a part for large-scale numerical workloads. Its 750 W TDP and OAM Module form factor confirm it belongs in a server or data center environment, not a desktop or laptop.

The Intel UHD Graphics 770 Mobile is an integrated processor with a 15 W TDP, 256 shading units, and full support for DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4. Its 12.80 GPixel/s pixel rate and 8 ROPs allow it to drive displays and render graphics for mobile systems. Its system shared memory and Ring Bus interface tie it directly to the host processor.

Benchmark results indicate no scenario where these parts compete. The database records zero wins for either side and no head-to-head entries. A user needing compute density and memory bandwidth has one option; a user needing integrated graphics output has the other. The MI300A cannot display an image, and the UHD 770 Mobile cannot approach the compute throughput or memory capacity of the MI300A. The choice is determined entirely by the workload, and the recorded specifications make that distinction unambiguous.
