AMD Radeon RX 7400 OEM vs Intel Arc Pro B65 Comparison

Where Each One Wins

The recorded data splits these two graphics cards into very different use-case profiles. The AMD Radeon RX 7400 OEM is built around minimal power draw and a compact single-slot physical design, while the Intel Arc Pro B65 is a professional-oriented board with substantially more memory, higher shader throughput, and a much wider memory bus.

Based on the specifications, the AMD card wins in scenarios where physical footprint and system power budget are the primary constraints. Its 55 W TDP and single-slot width allow installation in small-form-factor or dense OEM systems where the Intel card, with its 200 W TDP and dual-slot width, would not fit or would require a more substantial power supply. The AMD card also uses a single 6-pin power connector and suggests a 250 W PSU, whereas the Intel card requires an 8-pin connector and suggests a 550 W PSU. For pre-built office desktops or low-profile media PCs, the AMD part is the only viable choice.

The Intel Arc Pro B65 wins decisively in compute-heavy, memory-intensive, and professional workloads. Its 32 GB of GDDR6 memory is four times the capacity of the AMD card's 8 GB, and its 608.0 GB/s memory bandwidth is more than 3.5 times the AMD card's 172.8 GB/s. The Intel card also has 2560 shading units versus 1792 on the AMD, resulting in 12.29 TFLOPS FP32 throughput versus 7.885 TFLOPS. For tasks like large dataset processing, rendering with massive textures, or AI inference with large model footprints, the Intel card's memory capacity alone gives it a categorical advantage.

The data also shows the Intel card wins on raw pixel and texture throughput. Its 192.0 GPixel/s pixel rate is nearly triple the AMD's 70.40 GPixel/s, and its 384.0 GTexel/s texture rate is over triple the AMD's 123.2 GTexel/s. These metrics matter for high-resolution display output or multi-monitor professional setups.

Architecture Differences

The two cards come from entirely different architectural lineages. The AMD Radeon RX 7400 OEM uses the Navi 33 chip built on RDNA 3.0 architecture, codenamed Hotpink Bonefish. It belongs to the Navi III (RX 7000) generation and is fabricated on a 6 nm TSMC process. The Intel Arc Pro B65 uses the BMG-G21 chip based on Xe2-HPG architecture, belonging to the Battlemage (Pro Series) generation, fabricated on a 5 nm TSMC process.

The transistor counts differ significantly. AMD packs 13,300 million transistors into a 204 mm² die, giving a density of 65.2M transistors per mm². Intel packs 19,600 million transistors into a 272 mm² die, yielding a higher density of 72.1M per mm². The Intel chip is physically larger and more complex, which aligns with its higher TDP and expanded feature set.

Ray tracing hardware differs in count but not presence. The AMD card includes 28 ray tracing cores, while the Intel card has 20. This is notable because the Intel card has more total shaders (2560 vs 1792) but fewer dedicated RT units. The AMD card's higher RT core count may provide better ray tracing performance per-clock in supported workloads, though the Intel card's overall higher shader throughput could compensate in mixed workloads.

Memory architecture is a fundamental split. AMD uses a 128-bit memory bus with 8 GB of GDDR6 at 1350 MHz (10.8 Gbps effective). Intel uses a 256-bit bus with 32 GB of GDDR6 at 2375 MHz (19 Gbps effective). The bus width doubling and the higher memory clock combine to produce the 608.0 GB/s bandwidth figure. This is not just a capacity difference; the memory subsystem is designed for entirely different workload scales.

Clock behavior also differs dramatically. The AMD card has a base clock of 330 MHz and a boost of 1100 MHz, indicating a power-optimized design that runs at relatively low frequencies. The Intel card runs at a constant 2400 MHz for both base and boost, suggesting a stable, sustained-performance design without aggressive frequency scaling.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark runs for these two cards. Both have zero recorded benchmark scores, zero wins each, and an empty head-to-head benchmark array. The percentileVsAllGpus field shows both at the 50th percentile, which indicates neither has an established performance ranking against the broader GPU population in the database.

This absence of measured data is itself informative. The AMD Radeon RX 7400 OEM is an OEM-specific part, likely shipped inside pre-built systems where individual benchmark reporting is rare. The Intel Arc Pro B65 has a production status of "Active" and a release date of 2026-03-31, which may indicate it is too new for benchmark data to have accumulated in the database. The AMD card's release date of 2025-08-07 also suggests a relatively recent introduction, though it has had more time on the market.

Without measured scores, the specification-derived metrics serve as the only comparative basis. The FP32 throughput difference is substantial: 12.29 TFLOPS on the Intel card versus 7.885 TFLOPS on the AMD, a 55.8% advantage for Intel. The FP16 comparison is even more lopsided: the Intel card delivers 24.58 TFLOPS (2:1 ratio), while the AMD card delivers 7.885 TFLOPS (1:1 ratio). This means the Intel card has a 3.1x advantage in FP16 workloads, which are common in machine learning and certain scientific computing tasks.

Texture and pixel rates follow the same pattern. The Intel card's 384.0 GTexel/s versus AMD's 123.2 GTexel/s represents a 3.1x advantage. The pixel rate advantage is 2.7x (192.0 vs 70.40 GPixel/s). These are not marginal differences; they represent different performance tiers entirely.

The Verdict

The data presents two cards with fundamentally different design goals. The AMD Radeon RX 7400 OEM is a low-power, single-slot solution engineered for constrained OEM environments. Its 55 W TDP, 6-pin connector, and 250 W PSU recommendation make it suitable for systems where power delivery and physical space are limited. The 167 mm length and single-slot profile fit into compact chassis designs. Its 8 GB memory and 172.8 GB/s bandwidth are adequate for mainstream display tasks but not for heavy compute.

The Intel Arc Pro B65 is a professional workstation card aimed at memory-hungry and throughput-demanding applications. Its 32 GB memory capacity and 608.0 GB/s bandwidth support large datasets and high-resolution textures without swapping. The 2560 shading units and 12.29 TFLOPS FP32 deliver strong compute performance, while the 24.58 TFLOPS FP16 throughput (2:1 ratio) positions it for AI and scientific workloads. The PCIe 5.0 x16 interface provides double the bandwidth of the AMD card's PCIe 4.0 x8 connection, which matters for data transfer in compute tasks.

The choice between these cards depends entirely on the deployment scenario. For a small-form-factor office PC or a low-profile media system, only the AMD card fits the power and space envelope. For a professional workstation handling large 3D scenes, machine learning models, or multi-display setups, the Intel card's resources are necessary. The absence of measured benchmark data means the specification differences are the only available comparison, but those differences are so large in memory, bandwidth, and compute that the use-case separation is clear.

Both cards occupy the 50th percentile in the database's all-GPU ranking, but that percentile is based on zero recorded scores. The release dates suggest the AMD card has been available since 2025-08-07, while the Intel card is newer, dated 2026-03-31, with an Active production status. The Intel card's successor and predecessor fields are empty, while the AMD card lists Navi II as predecessor and Navi IV as successor, indicating AMD's product line has a defined roadmap while Intel's pro series is still establishing its lineage.

The data does not support a general-purpose recommendation. It supports a specific recommendation based on workload: choose the AMD Radeon RX 7400 OEM for power-constrained, space-constrained systems, and choose the Intel Arc Pro B65 for memory-intensive, high-throughput professional tasks. The 3.1x advantage in FP16 throughput and texture rate, combined with 4x memory capacity, makes the Intel card the only option for serious compute. The AMD card's 55 W TDP and single-slot design make it the only option for minimal systems.
