AMD Radeon 840M vs Intel Arc B570 Comparison

Where Each One Wins

The recorded data presents a stark contrast between the AMD Radeon 840M and the Intel Arc B570. These two processors occupy entirely different segments of the graphics hardware spectrum, and their benchmark results reflect that separation clearly.

The AMD Radeon 840M is an integrated graphics processor (IGP) built for the Krackan Point chip, operating within a 15 W power envelope. The database shows no benchmark entries for this part, meaning the recorded percentile of 50 against all GPUs is derived from its architectural position rather than direct test scores. Its role is to deliver basic graphics capability within a portable device, with all memory, bandwidth, and display outputs dependent on the host system.

The Intel Arc B570, by contrast, is a discrete dual-slot graphics card with a 150 W TDP. It has a substantial benchmark record. Its average benchmark score sits at 20,556 points, placing it in the 65th percentile of all GPUs in the database. The B570's nearest rivals in the database are the NVIDIA GeForce RTX 3070 Mobile at 20,534 points (0.1% ahead of the B570), the Intel Arc A750 at 20,582 points (0.1% behind), the NVIDIA Quadro M4000M at 20,480 points (0.4% ahead), and the AMD Radeon R9 M390X at 20,662 points (0.5% behind). This places the B570 in a tightly contested performance band where small percentage differences separate competitors.

The wins are therefore one-sided. The Intel Arc B570 wins every measurable benchmark category by virtue of having recorded scores at all. The AMD Radeon 840M, as an IGP with no dedicated benchmark results in the database, cannot claim a single numeric victory. The use-case split is clear: the 840M serves as an integrated solution for thin-and-light portable systems, while the B570 functions as a discrete card for desktop or larger laptop chassis.

Architecture Differences

The two chips come from different manufacturers and use different underlying technologies. The AMD Radeon 840M uses the RDNA 3.5 architecture, fabricated on a 4 nm process at TSMC. It belongs to the Navi III IGP generation for Strix Point Mobile. Its transistor count and die size are recorded as unknown in the database. The Intel Arc B570 uses the Xe2-HPG architecture, part of the Battlemage generation for Arc 5, fabricated on a 5 nm process also at TSMC. The B570 has a recorded transistor count of 19,600 million on a 272 mm² die, giving a transistor density of 72.1M per mm².

The compute resources differ by an order of magnitude. The 840M has 256 shading units, 16 texture mapping units, and 8 raster output pipelines. It includes 4 ray tracing cores. The B570 has 2,304 shading units, 144 TMUs, and 80 ROPs, with 18 ray tracing cores. The B570's shading unit count is exactly nine times that of the 840M. Its TMU count is also nine times higher, and its ROP count is ten times higher.

Clock behavior also differs. The 840M runs at a base clock of 400 MHz with a boost clock of 2900 MHz, a wide dynamic range typical of power-sensitive integrated parts. The B570 runs at a fixed 2500 MHz for both base and boost, indicating a constant operating point. Memory clocks show the B570 at 2375 MHz with 19 Gbps effective data rate, while the 840M uses system shared memory with system-dependent bandwidth.

The memory subsystem is a fundamental differentiator. The 840M shares system memory with the host CPU, with no dedicated VRAM. The B570 carries 10 GB of GDDR6 memory on a 160-bit bus, delivering 380.0 GB/s of bandwidth. This dedicated memory pool gives the B570 predictable and high-bandwidth access to data, whereas the 840M's performance depends entirely on the host system's memory configuration.

Both architectures support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The B570's FP16 throughput of 23.04 TFLOPS is exactly double its FP32 throughput of 11.52 TFLOPS, indicating a 2:1 ratio. The 840M's FP16 and FP32 are both 1,484.8 GFLOPS, a 1:1 ratio, meaning it does not use packed FP16 execution.

The Verdict

The data supports a straightforward conclusion. The Intel Arc B570 is a discrete graphics card with substantial compute resources, dedicated memory, and a full suite of recorded benchmarks that place it in the 65th percentile of all GPUs. It matches or slightly exceeds the performance of the NVIDIA GeForce RTX 3070 Mobile and the Intel Arc A750, with delta percentages of 0.1% in either direction. The AMD Radeon 840M, with its 15 W TDP, integrated design, and no recorded benchmarks, is a fundamentally different product aimed at basic graphics duties within portable devices.

For any workload requiring dedicated graphics performance, the B570 is the clear choice from the data. Its pixel rate of 200.0 GPixel/s and texture rate of 360.0 GTexel/s dwarf the 840M's 23.20 GPixel/s and 46.40 GTexel/s. The B570's FP32 throughput of 11.52 TFLOPS is nearly eight times the 840M's 1,484.8 GFLOPS. The B570 also supports up to three DisplayPort 2.1 outputs and one HDMI 2.1a output, while the 840M's display outputs are portable device dependent.

The 840M, however, fits a role the B570 cannot: it operates within a 15 W power budget, uses no power connectors, and requires no suggested PSU. The B570 needs a 150 W TDP budget, a single 8-pin power connector, and a 450 W suggested PSU. For a portable device where power efficiency is paramount, the 840M's integrated nature is appropriate. The data does not suggest the 840M competes with the B570 on any performance metric; it serves a different market segment entirely.

Head-to-Head Benchmarks

Since the AMD Radeon 840M has no recorded benchmarks, the head-to-head comparison relies entirely on the Intel Arc B570's measured results. The B570's performance can be broken down by test type to show where its strengths lie.

In 3DMark Steel Nomad DX12, the B570 records a score of 2,649. This is a modern DirectX 12 test that stresses the GPU's overall graphics pipeline. The B570's Geekbench scores are substantially higher: 83,514 in OpenCL and 96,844 in Vulkan. These compute-oriented tests show the B570's strength in general-purpose GPU workloads, with the Vulkan score exceeding the OpenCL score by roughly 16%.

The PassMark suite provides a more granular view. The B570 scores 14,195 in the G3D test, which is the overall 3D graphics mark. Its G2D score is 661, reflecting 2D rendering performance. The DirectX API-specific tests show variance: DirectX 9 scores 164, DirectX 11 scores 118, DirectX 12 scores 72, and DirectX 10 scores 65. This pattern suggests the B570 performs relatively better in older API workloads, with the DirectX 9 score more than double the DirectX 12 score. The GPU compute score in PassMark is 7,281.

The B570's nearest rival comparison reinforces its position. Against the Intel Arc A750, which scores 20,582, the B570 is 0.1% behind. Against the AMD Radeon R9 M390X, which scores 20,662, the B570 is 0.5% behind. Against the NVIDIA Quadro M4000M, which scores 20,480, the B570 is 0.4% ahead. These delta percentages are all within a single percentage point, indicating that the B570 sits in a competitive cluster where no single product dominates.

The absence of any benchmarks for the 840M means every recorded performance figure belongs to the B570. The margin between the two products cannot be expressed as a percentage because the 840M has no baseline score. What the data does show is that the B570's raw throughput figures, such as 11.52 TFLOPS FP32 and 200.0 GPixel/s pixel rate, are multiples of the 840M's corresponding figures.
