AMD Radeon 740M vs AMD Radeon RX 7600M XT Comparison

The AMD Radeon 740M and AMD Radeon RX 7600M XT represent two distinct tiers of AMD’s mobile graphics stack, both built on the RDNA 3.0 architecture but engineered for vastly different workloads. The data shows a decisive performance gap, with the RX 7600M XT dominating in every head-to-head benchmark, yet the 740M holds its own as a remarkably efficient integrated solution. This analysis draws exclusively on the benchmark scores and specification data provided, comparing the two parts across compute, graphics, and architectural fundamentals.

Head-to-Head Benchmarks

The head-to-head results are unambiguous. In the Geekbench OpenCL test, the AMD Radeon RX 7600M XT scores 74,869, while the AMD Radeon 740M manages 10,172. This represents an 86.4% delta in favor of the discrete GPU, meaning the RX 7600M XT delivers roughly 7.4 times the raw compute throughput of the integrated part. The OpenCL workload stresses general-purpose GPU compute, and the 20.23 TFLOPS FP32 rating of the RX 7600M XT versus the 2.867 TFLOPS of the 740M explains this massive disparity—the discrete chip simply has over seven times the shading units (2,048 vs. 256) and eight times the texture mapping units (128 vs. 16).

The Vulkan results tell a similar but slightly narrower story. The RX 7600M XT achieves 27,793 in Geekbench Vulkan, compared to 15,568 for the 740M, a 44% delta favoring the discrete GPU. The narrower gap in Vulkan suggests that the 740M’s architecture scales more efficiently in driver-optimized graphics workloads than in raw compute, likely due to its lower overhead and the integrated nature of the design. Still, the RX 7600M XT remains comfortably ahead, nearly doubling the 740M’s score.

Notably, the 740M has zero benchmark wins across the head-to-head suite, while the RX 7600M XT wins both. However, context from the nearestRivals data tempers this dominance. The 740M’s average benchmark score of 12,870 places it at the 53rd percentile of all GPUs, with rivals like the AMD Radeon RX 580 (12,928) just 0.4% ahead and the NVIDIA GeForce GTX 590 (12,830) only 0.3% behind. The RX 7600M XT’s average score of 12,710 sits at the 52nd percentile, with the NVIDIA GeForce GTX 670 (12,773) within 0.5% and the AMD Radeon Pro 455 (12,831) within 0.9%. This means that while the RX 7600M XT crushes the 740M in direct comparison, both parts occupy a similar tier when measured against the broader GPU landscape—proof of how far integrated graphics have come.

Where Each One Wins

The RX 7600M XT wins decisively in every scenario that demands sustained, high-throughput rendering or compute. Its 8 GB of dedicated GDDR6 memory on a 128-bit bus delivers 288.0 GB/s of bandwidth, compared to the 740M’s system-shared memory with bandwidth listed as “System Dependent.” For gaming at higher resolutions or texture-heavy workloads, this dedicated memory pool eliminates the contention with the CPU for system RAM, making the RX 7600M XT the clear choice for discrete-level performance. The 158.0 GPixel/s pixel rate and 316.0 GTexel/s texture rate dwarf the 740M’s 22.40 GPixel/s and 44.80 GTexel/s, respectively, meaning the discrete part can fill framebuffers and sample textures at nearly seven times the rate.

The 740M wins in efficiency and integration, though the data does not include direct power benchmarks. Its 45 W TDP versus the 120 W TDP of the RX 7600M XT indicates a significantly lower power draw, and its “IGP” slot width with no power connectors means it requires no additional cabling. For thin-and-light laptops where battery life and thermal headroom are paramount, the 740M is the rational choice. Its 4 nm process node at TSMC, versus the 6 nm node of the RX 7600M XT, also suggests superior transistor density—152.6M per mm² versus 65.2M per mm²—even though the 740M’s total transistor count of 20,900 million exceeds the RX 7600M XT’s 13,300 million. The 740M also supports PCIe 4.0 x8, which is sufficient for an integrated solution, while the RX 7600M XT uses the full x16 interface.

For legacy DirectX workloads, the PassMark scores reveal the RX 7600M XT’s versatility. It scores 175 in DirectX 9, 137 in DirectX 11, and 76 in DirectX 10, alongside 58 in DirectX 12 and 894 in G2D. The 740M has no PassMark data in the pack, so its legacy performance cannot be quantified, but the RX 7600M XT’s broad API support (DirectX 12 Ultimate, OpenGL 4.6, Vulkan 1.4) makes it more future-proof for a wider range of applications.

Specification Differences

The two GPUs differ substantially across nearly every specification field. The RX 7600M XT uses the Navi 33 chip, while the 740M uses Phoenix2. Process nodes differ: 6 nm for the RX 7600M XT versus 4 nm for the 740M. Transistor counts are 13,300 million (RX 7600M XT) versus 20,900 million (740M), with die sizes of 204 mm² and 137 mm², respectively. The RX 7600M XT has a base clock of 1280 MHz and boost of 2469 MHz, while the 740M runs at 800 MHz base and 2800 MHz boost—the integrated part actually boosts higher, but with far fewer execution units.

The RX 7600M XT features 2,048 shading units, 128 TMUs, and 64 ROPs, versus 256, 16, and 8 for the 740M. Ray tracing cores number 32 on the RX 7600M XT versus 4 on the 740M. Memory is the starkest difference: 8 GB GDDR6 at 288.0 GB/s on a 128-bit bus for the discrete part, versus system-shared memory with dependent bandwidth for the integrated part. The RX 7600M XT offers 20.23 TFLOPS FP32 and 40.45 TFLOPS FP16 (2:1), while the 740M delivers 2.867 TFLOPS for both FP32 and FP16 (1:1). Pixel rates are 158.0 GPixel/s versus 22.40 GPixel/s, and texture rates are 316.0 GTexel/s versus 44.80 GTexel/s. TDP is 120 W versus 45 W. The RX 7600M XT uses PCIe 4.0 x16, the 740M uses x8.

Architecture Differences

Both GPUs share the RDNA 3.0 architecture and are manufactured by TSMC, but the implementations diverge sharply. The RX 7600M XT is built on the Navi 33 chip, codenamed “Hotpink Bonefish,” part of the Navi Mobile generation (RX 7000M). The 740M uses the Phoenix2 chip, part of the Navi III IGP generation, with a predecessor of Navi II IGP and a successor of Navi III IGP. The RX 7600M XT’s predecessor is Polaris Mobile, with no listed successor.

The 740M’s 4 nm node allows for a transistor density of 152.6M per mm², which is over twice the 65.2M per mm² of the RX 7600M XT’s 6 nm node. This density advantage explains how the 740M packs 20,900 million transistors into a 137 mm² die, while the RX 7600M XT’s 13,300 million transistors require a larger 204 mm² die. The FP16 compute ratio differs significantly: the 740M operates at 1:1 FP16 to FP32 (2.867 TFLOPS each), while the RX 7600M XT doubles FP16 throughput to 40.45 TFLOPS via a 2:1 ratio, indicating shader-level dual-issue capability on the discrete part.

Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, with no tensor cores on either. Display outputs are environment-dependent: the 740M uses “Motherboard Dependent” outputs, while the RX 7600M XT uses “Portable Device Dependent.” The RX 7600M XT also has a game clock of 2023 MHz and memory clock of 2250 MHz (18 Gbps effective), details absent for the 740M. Ultimately, the RX 7600M XT is a dedicated mobile GPU designed for maximum throughput within a 120 W envelope, while the 740M is a high-density integrated solution optimized for efficiency within the CPU package.
