AMD Radeon RX 7700 XT vs Intel Arc Pro B390 Comparison

Where Each One Wins

The AMD Radeon RX 7700 XT and Intel Arc Pro B390 occupy entirely different performance tiers, and the recorded data confirms a decisive split. The RX 7700 XT delivers substantial wins across every benchmark category where measurements exist, while the Arc Pro B390 has no recorded benchmark scores in the database. This means the RX 7700 XT holds a clear advantage in all measurable workloads, from DirectX 9 legacy titles to modern DirectX 12 Ultimate scenarios and compute-heavy tasks.

The RX 7700 XT posts a PassMark G3D score of 22547, placing it at the 67th percentile among all GPUs in the database. Its average benchmark score sits at 22549. In contrast, the Arc Pro B390 shows an average benchmark score of 0 with no individual test results recorded, and it sits at the 50th percentile. The absence of benchmark data for the Intel part means the database cannot confirm any workload where it would outperform the AMD card.

For gaming workloads, the RX 7700 XT shows strong DirectX performance across multiple API generations. Its PassMark DirectX 11 score of 232 and DirectX 9 score of 294 indicate solid legacy API support, while the DirectX 12 score of 79 reflects modern API efficiency. The 3DMark Steel Nomad DX12 test returns a score of 3316, confirming the card handles current-generation rendering loads. The Arc Pro B390 lists DirectX 12 Ultimate (12_2) support in its API specifications, but without benchmark scores, its actual performance cannot be quantified.

Compute workloads also favor the AMD card decisively. The RX 7700 XT achieves a Geekbench OpenCL score of 138383 and a Geekbench Vulkan score of 46443. Its PassMark GPU Compute score is 12912. These numbers indicate strong general-purpose compute capability. The Intel part supports Vulkan 1.4 and OpenGL 4.6 per its specifications, but no compute benchmark results exist in the database to establish a comparative baseline.

Architecture Differences

The two GPUs use fundamentally different architectures, process nodes, and design philosophies. The AMD Radeon RX 7700 XT is built on the RDNA 3.0 architecture using the Navi 32 chip, manufactured on a 5 nm process at TSMC. It belongs to the Navi III (RX 7000) generation with the codename Wheat Nas. The Intel Arc Pro B390 uses the Xe3-LPG architecture with the Panther Lake chip, built on a 3 nm process at Intel's own foundry. It belongs to the Arc Graphics-WM (Panther Lake) generation.

Transistor counts and die sizes differ sharply, though the Intel data is incomplete. The RX 7700 XT contains 28,100 million transistors on a 346 mm² die, yielding a transistor density of 81.2M per mm². The Arc Pro B390 lists transistor count and die size as unknown, so no direct comparison is possible for those metrics.

The execution resource allocation shows a major disparity. The RX 7700 XT packs 3456 shading units, 216 texture mapping units, and 96 raster operation pipelines. It also includes 54 ray tracing cores. The Arc Pro B390 has 1536 shading units, 48 TMUs, and 24 ROPs, with 12 ray tracing cores. The AMD card has more than double the shading units, 4.5 times the TMUs, and 4 times the ROPs, which directly explains its higher pixel and texture throughput rates.

Clock behavior differs significantly as well. The RX 7700 XT has a base clock of 1435 MHz, a boost clock of 2544 MHz, and a game clock of 2171 MHz. The Intel part has a much lower base clock of 300 MHz but a boost clock of 2500 MHz, close to the AMD boost figure. The AMD card's memory clock runs at 2250 MHz with 18 Gbps effective data rate. The Intel GPU uses system shared memory, so its memory clock is listed as System Shared.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries between the RX 7700 XT and the Arc Pro B390. The head-to-head benchmark array is empty, and neither card records any wins in direct comparisons. This absence of paired test data means all performance conclusions must derive from the individual benchmark scores recorded for each card.

The RX 7700 XT's individual benchmark results provide the only measurable performance data. In 3DMark Steel Nomad DX12, it scores 3316. Geekbench OpenCL returns 138383, and Geekbench Vulkan returns 46443. PassMark results include 119 for DirectX 10, 232 for DirectX 11, 79 for DirectX 12, 294 for DirectX 9, 1161 for G2D, 22547 for G3D, and 12912 for GPU Compute. These scores establish the card's performance envelope across six distinct test categories.

The Arc Pro B390 has no benchmark scores recorded at all. Its average benchmark score is listed as 0, and its nearest rivals array is empty. Without any measured results, the database cannot assign it a performance ranking relative to the RX 7700 XT or any other GPU. Its 50th percentile placement appears to be a default value rather than a result derived from actual test data.

For the RX 7700 XT, the nearest rivals provide context for its standing. The NVIDIA GeForce RTX 5060 Mobile averages 22435, a 0.5 percent delta relative to the AMD card. The NVIDIA GeForce RTX 4060 Mobile averages 22729, a negative 0.8 percent delta. The NVIDIA GeForce RTX 2080 averages 22895, a negative 1.5 percent delta. The AMD Radeon RX 5700 averages 22170, a positive 1.7 percent delta. These comparisons show the RX 7700 XT sits within roughly two percentage points of several established desktop and mobile GPUs.

Specification Differences

The two cards differ across nearly every hardware specification in the database. The RX 7700 XT uses 12 GB of GDDR6 memory on a 192 bit bus, delivering 432.0 GB/s of bandwidth. The Arc Pro B390 uses System Shared memory with System Shared type, bus width, and bandwidth, meaning its memory performance depends entirely on the host system.

Power requirements show a stark contrast. The RX 7700 XT has a TDP of 245 W, requires a 550 W suggested PSU, uses dual-slot cooling, and needs two 8-pin power connectors.

The Verdict

The data supports only one conclusion for performance-oriented users: the AMD Radeon RX 7700 XT is the superior GPU in every measurable category. Its 35.17 TFLOPS FP32 throughput, 432.0 GB/s memory bandwidth, and 22547 PassMark G3D score place it firmly in the discrete desktop GPU tier. The Arc Pro B390, with 7.680 TFLOPS FP32 and system shared memory, cannot compete on raw specifications, and it has no benchmark scores to suggest otherwise.

For users who require a discrete card with dedicated VRAM, high throughput, and established performance across DirectX and compute workloads, the RX 7700 XT is the only option with recorded data to support a purchase decision. Its 12 GB GDDR6 memory and 245 W power envelope indicate a card designed for dedicated rendering tasks. The launch MSRP of 449 USD positions it as a mid-range discrete GPU at the time of release.

The Intel Arc Pro B390 serves a different purpose entirely. As an IGP with 80 W TDP and no power connectors, it targets integrated graphics scenarios where low power draw and compact form factor matter more than absolute performance. Its 1536 shading units and 12 ray tracing cores provide basic rendering capability, but the lack of recorded benchmarks means its real-world performance remains unverified in the database.

Users who need a dedicated GPU with proven benchmark results should choose the RX 7700 XT. Users who require an integrated solution with minimal power draw and no additional cooling or power delivery requirements should consider the Arc Pro B390, but they should be aware that no performance measurements exist to validate its capabilities. The database records no direct comparison between the two, and the specification gap is too wide to bridge with any reasonable expectation of parity.
