Apple M3 vs Intel Core i5-13600HX vs Apple M3 Pro 11-Core

Apple M3

The Apple M3 is a system on a chip (SoC) from Apple for notebooks that was introduced in late 2023. It integrates a new 8-core CPU with 4 performance cores with up to 4.06 GHz and 4 efficiency cores running at up to 2.75 GHz. Apple claims that the CPU is up to 20% faster than in the old Apple M2 (3.5 GHz). 

Due to the higher clock speeds and architecture improvements, the processor performance is also significantly better than the M2 in benchmarks (see e.g. Geekbench below) and can keep up with the fastest CPUs in short single-core tests (like the Raptor Lake i9-13950HX).

The M3 also integrates a new graphics adapter with dynamic caching, mesh shading and ray tracing acceleration called Apple M3 10-Core GPU. According to Apple, it is 20% faster than the GPU in the M2. The chip integrates again 10 GPU cores, but the cheaper variant only offers 8 cores (e.g. in the entry iMac). Later in early 2025 Apple also introduced a 9-core variant in the new iPad Air models. Furthermore, the GPU only supports 2 displays (an additional 6K60 display to the internal one).

Both GPU and CPU can access the unified memory on the package together. It is still available in 8, 16 and 24 GB variants and offers the same 100 GB/s maximum bandwidth (unlike the Pro models that feature a reduced memory bandwidth). 

The integrated 16-core Neural Engine has also been revised and now offers 18 TOPS peak performance (versus 15.8 TOPS in the M2 but 35 TOPS in the new A17 Pro). The video engine now supports AV1 decoding in hardware. H.264, HEVC and ProRes (RAW) can still be decoded and encoded.

Unfortunately, the integrated wireless network module only supports Wi-Fi 6E (no Wi-Fi 7) and due to the support of only a single external monitor, the chip also has to make do with no Thunderbolt 4 (Thunderbolt 3 / USB 4 support only for up to 40 Gbit/s).

The chip is manufactured on the current 3nm TSMC process (N3B most likely) and contains 25 billion transistors (+25% vs. Apple M2). The 3nm process should also contribute to the excellent efficiency of the chip. Under load, the M3 CPU consumes approximately 20 Watt.

Intel Core i5-13600HX

The Intel Core i5-13600HX is a fast mid-range mobile processor of the Raptor Lake series. Is was announced in early 2023 and integrates 6 fast Raptor Cove performance cores (P-cores) with HyperThreading and 8 Gracemont efficiency cores without HyperThreading. The P-Cores clock between 2.6 GHz (base) up to 4.8 GHz (single core boost, all-core 4.5 GHz). The smaller E-Cores clock between 1.9 and 3.6 GHz. All cores can access the combined 24 MB L3 cache. The CPU supports vPro (Enterprise) management features.

Compared to Alder Lake, Raptor Lake offers improved P-Cores (Raptor Cove micro-architecture) with bigger caches and more E-Cores (same Gracemont micro-architecture). Furthermore, the chip supports faster DDR5 memory (up to 5600 MHz for the 13980HX, but only 4800 MHz for the i5).

Performance

While we have not tested a single system built around the 13600HX as of August 2023, we have plenty of performance data for the i7-13650HX, a chip with almost the same specs (six P-cores mated to eight E-cores, with the latter running at the same clock speeds as what the 13600HX has and the former running at up to 100 MHz faster which is a very small difference). Based on that, we expect the 13600HX to be just a few percentage points behind the i7-13700HX and the i9-12950HX, meaning it's a very, very fast CPU, as of mid 2023.

Your mileage may vary depending on how competent the cooling solution of your laptop is, and how high the CPU power limits are.

Power consumption

The chip's "minimum assured" power consumption sits at 45 W. Its peak Turbo power consumption is not supposed to go over 157 W and its Intel-recommended Base power consumption is 55 W. Most laptop makers will probably go for a noticeably higher value to get better performance.

The i5-13600HX is built with Intel's 4th generation 10 nm process marketed as Intel 7 for average, as of early 2023, energy efficiency.

Apple M3 Pro 11-Core

The Apple M3 Pro 11 Core is a system on a chip (SoC) from Apple for notebooks that was introduced late 2023. It integrates 11 of the 12 CPU cores with 5 of 6 performance cores with up to 4.06 GHz and 6 efficiency cores with 2.8 GHz.

Compared to the M2 Pro the M3 Pro has been slimmed down somewhat and swaps two performance cores for efficiency cores. This is due to the changed core configuration, as 6 cores are now used per cluster (the M2 Pro and M3 still have 4 cores per cluster). Furthermore, the memory bus has been reduced from 256 bits to 192 bits (150 GB/s vs. 200 GB/s). Thanks to the new architecture and higher clock rates, the new M3 Pro is still slightly faster.

The M3 Pro also integrates a new graphics card with dynamic caching, mesh shading and ray tracing acceleration via hardware. In the entry-level model, only 14 of the chip's 18 cores are used and support up to 3 displays simultaneously (internal and 2 external).

GPU and CPU can jointly access the shared memory on the package (unified memory). This is available in 18 or 36 GB variants and offers 150 GB/s maximum bandwidth (192 bit bus).

The integrated 16-core Neural Engine has also been revised and now offers 18 TOPS peak performance (compared to 15.8 TOPS in the M2 but 35 TOPS in the new A17 Pro). The video engine now also supports AV1 decoding in hardware. H.264, HEVC and ProRes (RAW) can still be decoded and encoded.

Unfortunately, the integrated WLAN only continues to support WiFi 6E (no WiFi 7), unlike the small M3 SoC thunderbolt 4 is also supported (max 40 Gbit/s).

The chip is manufactured in the current 3nm process (N3B) at TSMC and contains 37 billion transistors (-7.5% vs. Apple M2 Pro).
