Architecture Differences

The architectural divide between these two GPUs is stark. The RX 570X is built on GCN 4.0 with the Polaris 20 chip, part of the Polaris (RX 500X) generation. It uses a 14 nm process at GlobalFoundries, packing 5,700 million transistors on a 232 mm² die. In contrast, the 740M uses RDNA 3.0 with the Phoenix2 chip, part of the Navi III IGP (Phoenix) generation. It is built on a 4 nm process at TSMC, which allows 20,900 million transistors on a smaller 137 mm² die.

The compute configurations diverge sharply. The RX 570X features 2048 shading units, 128 TMUs, and 32 ROPs. The 740M has only 256 shading units, 16 TMUs, and 8 ROPs. However, the 740M includes 4 ray tracing cores, a feature entirely absent from the RX 570X. The memory subsystems are also fundamentally different: the RX 570X uses 8 GB of GDDR5 on a 256-bit bus with 224.0 GB/s bandwidth, while the 740M relies on system shared memory with system-dependent bandwidth. This makes the 740M’s memory performance highly variable based on the host system.

The clock speeds tell an interesting story. The RX 570X has a base clock of 1168 MHz and a boost of 1244 MHz. The 740M has a much lower base of 800 MHz but a significantly higher boost of 2800 MHz. This suggests the 740M can ramp up aggressively under load but idles at lower speeds. The process node advantage of 4 nm over 14 nm explains how the 740M achieves higher clocks while consuming only 45 W TDP versus 150 W for the RX 570X. The RX 570X is a dual-slot card, while the 740M is an IGP with no slot width.

Head-to-Head Benchmarks

The single head-to-head benchmark result is decisive. In Geekbench OpenCL, the AMD Radeon RX 570X scores 38939, while the AMD Radeon 740M scores 10172. This gives the RX 570X a delta of 282.8% over the 740M. In practical terms, the RX 570X delivers roughly 3.8 times the raw compute output in this test. This is a massive gap that reflects the fundamental difference between a discrete GPU with dedicated memory bandwidth and an integrated solution sharing system resources.

The RX 570X’s victory in this test is consistent with its other benchmark scores. It achieves 1923 in Passmark G3D and 750 in Passmark G2D. The 740M lacks comparable Passmark scores in the data, but its Geekbench OpenCL score of 10172 is far below the RX 570X’s. The RX 570X also has a higher average benchmark score of 13871 versus 12870 for the 740M. While the 740M wins in Geekbench Vulkan with a score of 15568, there is no corresponding Vulkan score for the RX 570X in the data, so no direct comparison is possible.

Looking at nearest rivals, the RX 570X’s average score of 13871 places it just 0.4% ahead of the NVIDIA RTX A2000 Mobile (13821) and the AMD Radeon 660M (13812). It is 0.9% ahead of the AMD Radeon RX 7900 XT (13745) and 1.1% behind the NVIDIA Tesla K10 (14029). The 740M’s average score of 12870 is 0.2% ahead of the AMD FirePro W5100 (12847), 0.3% ahead of both the AMD Radeon Pro 455 (12831) and NVIDIA GeForce GTX 590 (12830), and 0.4% behind the AMD Radeon RX 580 (12928). These rival positions show that the RX 570X sits in a slightly higher performance tier overall.

Specification Differences

The two GPUs differ in nearly every measurable specification. The RX 570X uses the Polaris 20 chip on GCN 4.0 architecture, while the 740M uses the Phoenix2 chip on RDNA 3.0. The process nodes are 14 nm (GlobalFoundries) versus 4 nm (TSMC), with transistor counts of 5,700 million versus 20,900 million, and die sizes of 232 mm² versus 137 mm². Transistor density is 24.6M per mm² for the RX 570X and 152.6M per mm² for the 740M.

Clock speeds differ significantly. The RX 570X has a base clock of 1168 MHz and a boost of 1244 MHz. The 740M has a base of 800 MHz and a boost of 2800 MHz. The RX 570X has dedicated GDDR5 memory of 8 GB on a 256-bit bus with 224.0 GB/s bandwidth. The 740M uses system shared memory with a system-dependent bus width and bandwidth. The compute units differ wildly: 2048 shading units, 128 TMUs, and 32 ROPs for the RX 570X versus 256 shading units, 16 TMUs, and 8 ROPs for the 740M. The 740M has 4 ray tracing cores; the RX 570X has none.

Power and physical specifications also diverge. The RX 570X has a TDP of 150 W, is dual-slot, requires a 1x 6-pin power connector, and a 450 W suggested PSU. The 740M has a TDP of 45 W, is an IGP, needs no power connectors, and has no suggested PSU. The bus interface is PCIe 3.0 x16 for the RX 570X versus PCIe 4.0 x8 for the 740M. Display outputs are 1x DVI, 1x HDMI 2.0b, and 3x DisplayPort 1.4a for the RX 570X, while the 740M’s outputs are motherboard dependent. The RX 570X is 241 mm long, while the 740M has no listed physical dimensions. The RX 570X supports DirectX 12 (12_0), while the 740M supports DirectX 12 Ultimate (12_2). Both support OpenGL 4.6, but the RX 570X supports Vulkan 1.3 and the 740M supports Vulkan 1.4.

The Verdict

The data presents a clear verdict for raw performance: the AMD Radeon RX 570X is the superior GPU in compute benchmarks. Its Geekbench OpenCL score of 38939 dwarfs the 740M’s 10172, a 282.8% advantage. The RX 570X also has a higher average benchmark score (13871 versus 12870) and a higher percentile ranking (55th versus 53rd). For any workload that relies heavily on raw shader throughput, the RX 570X is the definitive choice.

However, the 740M is not without merit. Its 4 nm process and RDNA 3.0 architecture deliver modern features like 4 ray tracing cores and DirectX 12 Ultimate support, which the RX 570X lacks. The 740M also operates at a fraction of the power draw (45 W versus 150 W) and requires no external power connectors. Its higher boost clock of 2800 MHz indicates strong peak performance potential, even if its smaller shader count limits overall throughput. The 740M’s Vulkan 1.4 support is also ahead of the RX 570X’s Vulkan 1.3.

The RX 570X is end-of-life, while the 740M is active production. The RX 570X’s predecessor is Polaris and its successor is Vega, while the 740M’s predecessor is Navi II IGP and successor is Navi III IGP. The RX 570X was released in 2018, while the 740M arrived in 2024. Neither has a launch MSRP listed in the data.

Where Each One Wins

The AMD Radeon RX 570X wins decisively in raw compute performance. Its 282.8% lead in Geekbench OpenCL makes it the clear choice for applications that stress traditional shading units, such as rendering, compute-heavy workloads, or gaming at higher resolutions where dedicated memory bandwidth matters. The 224.0 GB/s of dedicated GDDR5 bandwidth versus system-shared memory gives it a major advantage in memory-intensive tasks. Its higher average benchmark score and better percentile ranking confirm its overall performance superiority.

The AMD Radeon 740M wins in efficiency and modern features. Its 45 W TDP versus 150 W makes it suitable for compact, power-constrained systems. The 4 ray tracing cores and DirectX 12 Ultimate support enable hardware-accelerated ray tracing, which the RX 570X cannot do. The 740M’s 2800 MHz boost clock and 4 nm process represent a newer, more advanced design. Its Vulkan 1.4 support is a generation ahead of the RX 570X’s Vulkan 1.3. The 740M also benefits from being an active product, while the RX 570X is end-of-life.

For users prioritizing maximum frame rates and compute throughput, the RX 570X is the data-backed winner. For users prioritizing power efficiency, modern API support, and ray tracing capability, the 740M is the logical pick. The RX 570X’s nearest rival positioning (0.4% ahead of the RTX A2000 Mobile) shows it competes with professional mobile GPUs, while the 740M’s rivals (0.4% behind the RX 580) place it in the older discrete GPU performance tier. The choice ultimately depends on whether raw performance or architectural modernity matters more.
