AMD Radeon PRO W7400 vs Intel UHD Graphics 770 Mobile Comparison

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries for the AMD Radeon PRO W7400 versus the Intel UHD Graphics 770 Mobile. Both GPUs hold identical percentile rankings at 50.0 across all GPUs in the database, with average benchmark scores of 0 for each. This absence of recorded comparative measurements means the performance relationship must be derived from the architectural and specification data available.

The raw compute figures show a substantial gap. The AMD Radeon PRO W7400 delivers 7.885 TFLOPS of FP32 throughput, while the Intel UHD Graphics 770 Mobile manages 819.2 GFLOPS. That places the AMD part at roughly 9.6 times the single-precision compute throughput of the Intel integrated solution. In FP16 workloads, the AMD card sustains 7.885 TFLOPS with a 1:1 ratio, whereas the Intel part reaches 1.638 TFLOPS with a 2:1 ratio, meaning the AMD advantage narrows to approximately 4.8 times but remains decisive.

Texture and pixel rates reinforce the same hierarchy. The Radeon PRO W7400 produces 123.2 GTexel/s and 70.40 GPixel/s. The Intel UHD Graphics 770 Mobile produces 25.60 GTexel/s and 12.80 GPixel/s. The AMD card is 4.8 times faster in texture fill and 5.5 times faster in pixel throughput. These ratios align closely with the shading unit and TMU counts, where the AMD chip fields 1792 shading units and 112 TMUs against Intel's 256 shading units and 16 TMUs.

Memory bandwidth creates an even wider separation. The Radeon PRO W7400 accesses 8 GB of GDDR6 across a 128-bit bus, yielding 172.8 GB/s. The Intel part uses System Shared memory with bandwidth described as System Dependent, which in practice ties performance to the host platform's memory configuration. The discrete AMD card's dedicated bandwidth advantage is not quantifiable against a system-dependent figure, but the architectural separation between a dedicated 172.8 GB/s GDDR6 implementation and a shared-memory design is unambiguous.

Clock behavior differs in an interesting way. The Intel part boosts to 1600 MHz from a 300 MHz base, while the AMD card boosts to 1100 MHz from a 330 MHz base. Despite the Intel chip's higher boost clock, its smaller execution resources cannot overcome the AMD card's raw throughput advantages. The AMD card's lower boost clock with 7 times the shading units and 7 times the TMUs produces the far higher aggregate throughput.

Architecture Differences

The two GPUs come from fundamentally different design philosophies. The AMD Radeon PRO W7400 uses the Navi 33 chip built on RDNA 3.0 architecture, codenamed Hotpink Bonefish, manufactured by TSMC on a 6 nm process. The Intel UHD Graphics 770 Mobile uses the Raptor Lake chip on Generation 12.2 architecture, manufactured by Intel on a 10 nm process. The process node difference gives AMD a density advantage, though the Intel part carries no published transistor count or die size in the database.

The AMD chip integrates 13,300 million transistors on a 204 mm² die, producing a transistor density of 65.2M per mm². The Intel part lists no transistor count, die size, or density figures. The AMD GPU belongs to the Radeon Pro Navi (Navi III Series) generation and lists Radeon Pro Vega as its predecessor. The Intel GPU belongs to the HD Graphics-M (Raptor Lake) generation and lists Arc Graphics-M as its successor.

Execution resource differences are stark. The AMD card provides 1792 shading units, 112 TMUs, 64 ROPs, and 28 ray tracing cores. The Intel part provides 256 shading units, 16 TMUs, and 8 ROPs, with no ray tracing cores listed. The AMD card also enables hardware ray tracing through its 28 dedicated RT cores, a capability entirely absent from the Intel integrated GPU's specification sheet.

Memory architecture separates the two designs completely. The AMD Radeon PRO W7400 uses 8 GB of GDDR6 on a 128-bit interface with 172.8 GB/s bandwidth, running at 1350 MHz (10.8 Gbps effective). The Intel UHD Graphics 770 Mobile relies on System Shared memory, with System Shared type, bus width, and System Dependent bandwidth. This makes the Intel part's memory performance platform-dependent rather than a fixed specification.

Power and physical design differ by class. The AMD card has a 55 W TDP, occupies a single slot, requires no power connectors, and suggests a 250 W power supply. It measures 168 mm in length, 69 mm in height, and 20 mm in width. The Intel part has a 15 W TDP, is an IGP with no slot width, no power connectors, no suggested PSU, and no listed dimensions. The AMD card connects via PCIe 4.0 x8, while the Intel part uses a Ring Bus interface.

Display output capability also diverges. The AMD card provides 4x DisplayPort 2.1 outputs. The Intel IGP's display outputs are described as Portable Device Dependent, reflecting its integrated role in mobile systems. API support shows the AMD card at DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The Intel part reaches DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4, meaning the AMD card supports a higher DirectX feature level.

The Verdict

The recorded data points to two GPUs serving entirely different roles. The AMD Radeon PRO W7400 is a discrete workstation accelerator with dedicated memory, hardware ray tracing, and roughly 9.6 times the FP32 throughput of the Intel UHD Graphics 770 Mobile. The Intel part is an integrated graphics solution with a 15 W TDP, shared system memory, and no ray tracing hardware, designed for basic display and light acceleration duties inside mobile processors.

For workloads that stress raw compute, texture throughput, pixel fill, or memory bandwidth, the AMD card holds every measurable advantage. Its 172.8 GB/s dedicated GDDR6 bandwidth versus System Dependent shared memory removes the Intel part from contention in memory-intensive tasks. Its 28 ray tracing cores enable hardware-accelerated ray tracing that the Intel IGP cannot perform at all. Its 7.885 TFLOPS FP32 throughput versus 819.2 GFLOPS establishes a compute gap that no clock frequency difference can close.

The Intel part does hold advantages in power consumption and form factor. Its 15 W TDP versus the AMD card's 55 W TDP makes it suitable for platforms where power and space constraints preclude any discrete GPU. Its 1600 MHz boost clock exceeds the AMD card's 1100 MHz boost, and its status as an IGP means no additional board space, cooling, or power delivery is required. These factors matter in ultraportable and low-power designs, but they do not translate into competitive performance in the database's measured categories.

The production status for both parts is Active. The AMD card released on 2025-08-02, while the Intel part released on 2023-01-03. The AMD card has no successor listed, while the Intel part's successor is Arc Graphics-M. Neither part carries a launch MSRP in the database, so no pricing analysis is possible from the recorded data.
