AMD Ryzen 3 2300U vs Intel Core i7-3540M Comparison

The Intel Core i7-3540M and AMD Ryzen 3 2300U are both mobile processors aimed at thin-and-light laptops, but they represent two very different eras of design. The Intel chip is a dual-core Ivy Bridge part from early 2013, while the AMD is a quad-core Raven Ridge part from five years later. Benchmark data shows a clear overall winner: the Ryzen 3 2300U secures all three head-to-head victories, with an average benchmark score of 880 against 867 for the Intel. Despite this, the Intel part remains competitive in specific legacy workloads, and the architectural gulf between the two explains nearly every performance difference observed.

Where Each One Wins

The AMD Ryzen 3 2300U is the outright winner in every direct benchmark comparison available. It takes the Cinebench R15 multi-core test with a score of 422.5 against the Intel’s 254, a massive 39.9% deficit for the older chip. In Geekbench multi-core, the AMD doubles up the Intel: 2234 versus 1160, a 48.1% gap. Even in single-core Geekbench, where Intel’s higher boost clock might be expected to help, the Ryzen wins by 27.8%, scoring 783 versus 565. This is not a narrow victory; the AMD part dominates across the board.

The Intel Core i7-3540M has no benchmark wins in this dataset. However, it does not lose every category by the same margin. Its single-core Geekbench score of 565 is closer to the AMD’s 783 than its multi-core score is, suggesting that the Intel part is relatively less disadvantaged in single-threaded tasks. The data also shows the Intel chip holds its own in specific Cinebench R20 and R23 results, where it scores 1060 (R20 multi), 149 (R20 single), 2525 (R23 multi), and 356 (R23 single). These numbers are not directly compared to the AMD, but they indicate the Intel part is fully functional for lighter productivity workloads. In short, the Ryzen 3 2300U wins every head-to-head, while the i7-3540M’s only saving grace is that its single-core deficit is smaller than its multi-core one.

Architecture Differences

The two CPUs are built on fundamentally different blueprints. Intel’s i7-3540M uses the Ivy Bridge architecture on a 22 nm process, with a die size of 118 mm². It packs 2 cores and 4 threads, with a base clock of 3.00 GHz and a boost of 3.70 GHz. The L3 cache is 4 MB shared, while L1 and L2 are 64 KB and 256 KB per core, respectively. The chip is built by Intel and supports DDR3 memory on a dual-channel bus. Its integrated graphics is the Intel HD 4000.

AMD’s Ryzen 3 2300U is a Zen-based Raven Ridge part fabricated on a 14 nm process by GlobalFoundries. It has 4 cores and 4 threads, meaning no simultaneous multithreading—each core is a physical core. The base clock is listed at 2000.00 MHz (2.00 GHz) with a boost of 3.40 GHz. The L3 cache is also 4 MB shared, but L1 is 96 KB per core and L2 is 512 KB per core. It uses DDR4 memory on a dual-channel bus, with a memory bandwidth of 38.4 GB/s. The integrated graphics is Radeon Vega 6, and the CPU supports PCIe Gen 3 with 8 lanes. The die size is 210 mm², and the transistor count is 4,950 million.

The process node difference (22 nm versus 14 nm) and the core count difference (2 versus 4) are the most significant architectural factors. The Ryzen also has a much lower TDP of 15 watts versus 35 watts for the Intel, which is a major efficiency advantage. The Intel part uses a Socket G2 (988B), while AMD uses Socket FP5. The memory generation (DDR3 vs DDR4) and the integrated graphics (HD 4000 vs Vega 6) further separate the two.

Head-to-Head Benchmarks

The three direct head-to-head results paint a consistent picture of AMD dominance. The largest margin is in Geekbench multi-core, where the Ryzen 3 2300U scores 2234 and the i7-3540M scores 1160. This is a 48.1% win for AMD. The gap is explained by the core count: the Ryzen has double the physical cores. In Cinebench R15 multi-core, the AMD wins by 39.9% with a score of 422.5 versus 254. This test is highly sensitive to core count and multi-threading, and the Intel’s 2-core/4-thread configuration simply cannot keep up.

The closest head-to-head is in Geekbench single-core, where the AMD still wins by 27.8% (783 vs 565). This is notable because single-core performance is less dependent on core count and more dependent on IPC (instructions per clock) and clock speed. The Intel part has a higher boost clock (3.70 GHz vs 3.40 GHz), but the Ryzen’s Zen architecture delivers higher IPC, making the clock speed advantage irrelevant. The data shows that even in a test that favors the Intel’s higher frequency, the architectural superiority of Zen wins.

There is no single-core Cinebench R15 result for the Intel part in the head-to-head list, but the AMD’s score of 79 in that test is available. The Intel’s R20 single-core score is 149, which is not directly comparable. The overall pattern is clear: the Ryzen 3 2300U wins every benchmark by a margin between 27.8% and 48.1%.

FAQ

Q: Which CPU has more physical cores?

A: The AMD Ryzen 3 2300U has 4 physical cores, while the Intel Core i7-3540M has 2 physical cores. Both have 4 threads, but the AMD does not use SMT (simultaneous multithreading), so its 4 threads come from 4 distinct cores.

Q: Is the Intel chip faster in any benchmark?

A: No. In the three head-to-head benchmarks available (Cinebench R15 multi-core, Geekbench multi-core, Geekbench single-core), the AMD Ryzen 3 2300U wins all of them. The Intel chip has zero wins in the head-to-head data.

Q: Which CPU has a lower TDP?

A: The AMD Ryzen 3 2300U has a TDP of 15 watts, while the Intel Core i7-3540M has a TDP of 35 watts. This makes the AMD part significantly more power-efficient.

Q: How do their integrated graphics compare?

A: The Intel part features Intel HD 4000 graphics, while the AMD part features Radeon Vega 6 graphics. The data does not include direct graphics benchmark comparisons, but the architectural differences (Vega 6 vs HD 4000) are substantial.

Specification Differences

The two processors differ in nearly every major specification category. The core count is the most obvious: Intel has 2 cores and 4 threads, while AMD has 4 cores and 4 threads.
