AMD Radeon RX 5600 OEM vs Intel Arc A770 Comparison

Where Each One Wins

The recorded data presents a clear asymmetry in benchmark performance between these two end-of-life graphics cards. The Intel Arc A770, representing the Alchemist generation, demonstrates dominance across every measured workload in the database, while the AMD Radeon RX 5600 OEM, from the RDNA 1.0 architecture, shows no victories in the head-to-head comparisons.

The Arc A770 secures wins in both available benchmark categories, which include Geekbench OpenCL and Geekbench Vulkan tests. These two tests cover distinct API environments, with OpenCL representing general compute workloads and Vulkan representing modern graphics and compute tasks. The fact that Intel's card wins both indicates a consistent advantage rather than a workload-specific strength.

For the AMD Radeon RX 5600 OEM, the data shows zero benchmark wins. This does not necessarily indicate failure in all real-world scenarios, but within the recorded measurements, it trails its competitor in every category. The RX 5600 OEM's positioning in the database's percentile rankings, at 87th percentile versus the Arc A770's 90th percentile, further contextualizes its performance tier.

The use-case split is straightforward: the Intel Arc A770 is the superior performer in both synthetic compute and graphics API tests. The AMD card, while still a capable product, occupies a lower performance bracket. Users prioritizing maximum compute throughput or Vulkan-based workloads would find the data favoring Intel decisively.

Architecture Differences

The architectural gap between these two GPUs is substantial and explains much of the performance differential. Intel's Arc A770 utilizes the DG2-512 chip built on the Xe-HPG architecture, manufactured on a 6 nm process at TSMC. The die measures 406 mm² and contains 21,700 million transistors, resulting in a transistor density of 53.4 million per square millimeter.

AMD's RX 5600 OEM employs the Navi 10 chip with RDNA 1.0 architecture, also fabricated by TSMC but on a 7 nm process. Its die size is 251 mm² with 10,300 million transistors, yielding a lower density of 41.0 million per square millimeter. The process node advantage belongs to Intel, which uses a smaller 6 nm node compared to AMD's 7 nm.

Core configuration differences are pronounced. The Arc A770 features 4096 shading units, 256 texture mapping units, and 128 raster output units. It also includes 32 dedicated ray tracing cores. The RX 5600 OEM offers 2048 shading units, 128 TMUs, and 64 ROPs, with no dedicated ray tracing hardware listed in the database. This represents a doubling of shader, texture, and raster resources for Intel.

Clock speeds tell a complementary story. The Arc A770 operates at a base clock of 2100 MHz and boosts to 2400 MHz. AMD's card runs at a base of 1130 MHz, a game clock of 1375 MHz, and a boost of 1560 MHz. Even accounting for architectural differences, Intel's higher clocks contribute to its throughput advantage.

Memory subsystems differ significantly. The Arc A770 carries 16 GB of GDDR6 on a 256-bit bus, delivering 512.0 GB/s of bandwidth. The RX 5600 OEM has 6 GB of GDDR6 on a 192-bit bus, providing 288.0 GB/s. The memory clock rates also differ, with Intel at 2000 MHz (16 Gbps effective) versus AMD's 1500 MHz (12 Gbps effective).

Compute rates reflect these structural advantages. The Arc A770 achieves 19.66 TFLOPS FP32 and 39.32 TFLOPS FP16 (2:1 ratio). The RX 5600 OEM delivers 6.390 TFLOPS FP32 and 12.78 TFLOPS FP16 (2:1 ratio). Pixel and texture rates follow suit: 307.2 GPixel/s and 614.4 GTexel/s for Intel versus 99.84 GPixel/s and 199.7 GTexel/s for AMD.

Power characteristics differ as well. The Arc A770 has a TDP of 225 W with a suggested PSU of 550 W, using one 6-pin and one 8-pin connector. The RX 5600 OEM has a 125 W TDP, a 300 W suggested PSU, and requires a single 8-pin connector. Both cards are dual-slot designs with PCIe 4.0 x16 interfaces.

API support shows minor differences. Intel supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. AMD supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4. Display outputs differ, with Intel offering one HDMI 2.1 and three DisplayPort 2.0 ports, while AMD provides one HDMI 2.0b and three DisplayPort 1.4a outputs.

Head-to-Head Benchmarks

The database contains two direct comparison benchmarks, and Intel wins both by substantial margins. These results provide concrete evidence of the performance gap between these products.

The Geekbench OpenCL test shows the Arc A770 scoring 109,175 points against the RX 5600 OEM's 62,427 points. This represents a 74.9% advantage for the Intel card. In practical terms, the Arc A770 delivers nearly 75% more compute performance in this general-purpose GPU compute workload. This aligns with its higher shader count, clock speeds, and memory bandwidth, all of which contribute to compute throughput.

The Geekbench Vulkan test yields a similar outcome. Intel scores 94,284 points while AMD manages 53,743 points, resulting in a 75.4% delta favoring the Arc A770. Vulkan is a low-level graphics and compute API, and Intel's advantage here suggests strong driver optimization or inherent architectural efficiency in this workload.

These deltas are remarkably consistent, differing by only 0.5 percentage points between tests. This consistency implies that the performance gap is structural rather than workload-dependent. The Arc A770's advantages in raw resources, memory bandwidth, and clock speeds translate uniformly across different API environments.

Looking at the broader database context, the Arc A770's average benchmark score is 68,809, while the RX 5600 OEM averages 58,085. This represents a difference of 10,724 points, or approximately 18.5% in the average score. The average includes all recorded benchmarks for each card, providing a more holistic view than the head-to-head tests alone.

The Intel card's nearest rivals in the database include the NVIDIA CMP 90HX with an average score of 69,000 (0.3% higher), the AMD Radeon Instinct MI25 at 68,562 (0.4% lower), the AMD Radeon Pro WX 8200 at 69,870 (1.5% higher), and the NVIDIA Quadro P6000 at 69,986 (1.7% higher). This places the Arc A770 in a competitive tier with professional and mining-oriented products.

For the RX 5600 OEM, its nearest rivals include the Intel Arc A570M at 58,239 (0.3% higher), the AMD Radeon RX 6950 XT at 58,392 (0.5% higher), the Intel Arc A580 at 57,756 (0.6% lower), and the NVIDIA P102-100 at 58,528 (0.8% higher). The RX 5600 OEM sits in a mid-range bracket where performance differences among neighbors are minimal.

The Verdict

The recorded data supports a clear verdict for most users. The Intel Arc A770 outperforms the AMD Radeon RX 5600 OEM across all measured benchmarks, with margins exceeding 74% in both OpenCL and Vulkan tests. Its average benchmark score is approximately 18.5% higher, and it holds a better percentile ranking at 90 compared to AMD's 87.

Users who prioritize compute performance, modern API support, or ray tracing capabilities should select the Intel Arc A770. The data shows it provides 32 ray tracing cores, 16 GB of memory with 512.0 GB/s bandwidth, and supports DirectX 12 Ultimate. These features position it for more demanding workloads and newer applications.

Users with power constraints or older system compatibility might consider the RX 5600 OEM despite its lower performance. The data shows a 125 W TDP versus Intel's 225 W, and a suggested PSU of 300 W versus 550 W. This makes AMD's offering easier to integrate into existing systems with smaller power supplies. However, the performance penalty is substantial, and the RX 5600 OEM lacks ray tracing hardware entirely.

The RX 5600 OEM also offers a lower transistor count and smaller die size, which historically correlates with lower manufacturing costs, but the database does not include pricing information for this card. The Arc A770 has a launch MSRP of 329 USD, stated once here for reference.

For gaming, modern titles increasingly leverage DirectX 12 Ultimate features, which favors Intel. For legacy applications or compute tasks that rely on OpenGL, both cards support OpenGL 4.6, but Intel's raw compute advantage remains decisive.

The production status for both cards is end-of-life, so neither represents a future-proof investment. Within the context of what the data shows, the Intel Arc A770 is the superior choice for performance-focused users, while the RX 5600 OEM may serve users with strict power budgets or minimal performance requirements.
