Apple M2 Pro 12-core vs M4: newer doesn't mean faster

The full M2 Pro is eight performance cores, four efficiency cores, and a 19-core GPU. The M4 is four performance cores, six efficiency cores, and ten GPU cores. Almost two years and a full process node separate them, yet in most tests the older 2023 chip doesn't fall behind the 2024 mainstream part, and in graphics it pulls ahead by half.

This is not a case where the new generation settles the argument. The M4 takes single-core by more than 40 percent and runs noticeably cooler on power. Multi-core depends entirely on which benchmark you trust, and there is no clear winner there.

The practical side: as of fall 2026 the 12-core M2 Pro exists only on the used market, and the M4 has nearly vanished from new retail. The M4 Mac mini is discontinued, its M6 replacement ships September 22, the MacBook Pro moved to the M5 in October 2025, and the MacBook Air followed in March 2026. The iMac is essentially the last new machine you can buy with one.

Key differences

Lineup position and architecture

The 12-core M2 Pro is the complete die. The 10-core version is the same silicon with two performance CPU cores and three GPU cores switched off, and the multi-core gap between them runs as high as 20 percent. Both use a 256-bit memory bus, which is the real marker of the Pro class.

The M4 follows a different logic: a mainstream die on a 128-bit bus, but built on 3 nm, with cores clocked to 4.4 GHz and graphics two generations newer. Eight performance cores against four is exactly why the process advantage doesn't translate into a lead when every thread is loaded.

One detail that matters when shopping: the 12-core M2 Pro always shipped with the 19-core GPU. There were no other combinations.

CPU performance

Single-core isn't up for debate. Geekbench 6 gives the M4 3,777 points against 2,666, and Cinebench 2024 puts it at 172 against 125. That's 42 and 38 percent, and you feel it in the browser, in interface response, in single-threaded plugins, and when compiling small targets.

Multi-core splits into contradictory results, and that's the takeaway of this section:

• Cinebench 2024: 982 against 795, the M4 ahead by 24 percent;
• Geekbench 6 on the same sample set: 14,818 against 14,489, a wash;
• Geekbench Browser averages for specific machines: 15,353 for the M4 Mac mini against 16,561 for the M2 Pro MacBook Pro 14, about 8 percent to the older chip;
• PassMark: 26,724 against 23,603, the M2 Pro ahead by 13 percent.

The spread comes down to the type of load. A pure render like Cinebench hammers every core equally, and there four modern performance cores plus six efficiency cores do better work. The mixed workloads in Geekbench and PassMark sit closer to how a system actually behaves, and there the M2 Pro's eight full-size cores earn their keep.

So: if multi-core means Blender, HandBrake, or a Compressor export, the M4 is roughly a quarter faster. If it means parallel builds, virtual machines, and a dozen heavy apps at once, the M2 Pro comes out ahead.

Graphics

Here the gap leaves no room for interpretation. In Geekbench 6 Metal the M2 Pro MacBook Pro 14 scores 82,726 against 54,060 for the M4 Mac mini, a 53 percent lead. In 3DMark Wild Life Extreme Unlimited the 19-core GPU posts 12,983 against roughly 9,140, a 42 percent gap.

In class terms, the 19-core M2 Pro closes on a mobile GeForce RTX 4050 (13,655 points), while the M4 sits right next to an RTX 3050. That's a full segment apart.

The one exception is ray tracing. The M2 Pro has no hardware RT block, and in ray-traced rendering the newer architecture erases most of the core-count advantage: the 16-core M2 Pro finishes the Blender 3.3 Classroom scene via Metal in 132 seconds against 103 for the M4. With 19 cores the older chip should land around the M4's level, but no database has direct measurements of that configuration, so parity is the honest call rather than a win.

Memory adds to the M2 Pro's case: 200 GB/s against 120 GB/s directly caps generation speed on local language models at the same 32 GB of capacity.

Results from specific machines

The numbers below are Geekbench Browser averages. They run lower than single-run review scores because every submitted result is folded in. For comparing machines against each other that doesn't matter.

The three M2 Pro machines land within two percent of each other, so in short bursts the chassis decides nothing. The 16-inch laptop's larger cooling system only pays off under sustained load. The more interesting line is the Mac mini, which matches the laptops even though a desktop enclosure has far more thermal headroom. Apple never raised the power limits for the mini, and the chip runs in the same envelope.

Power and battery life

The 12-core M2 Pro only went into actively cooled machines: the MacBook Pro 14 and 16 and the Mac mini. The M4, with the same CPU core count, fits inside a fanless MacBook Air, which says everything about the difference in appetite.

In the same chassis Apple's own claims read like this: 24 hours of video for the M4 MacBook Pro 14, 18 hours for the same laptop with the M2 Pro. For desktop work it isn't an argument. The M4 Mac mini stayed under 50 watts at the wall in testing with a 43.4 degree Celsius peak, and both machines are quiet.

Real machines, prices, and availability

Nothing new has shipped with a 12-core M2 Pro since fall 2023 for laptops and October 2024 for the Mac mini. The launch prices were $2,499 for the MacBook Pro 14 in its 12-core configuration, $2,499 for the base MacBook Pro 16, and a paid upgrade on top of the $1,299 Mac mini.

Today it's a used market, and a lopsided one. A 16-inch M2 Pro MacBook Pro in good condition starts around $933, which is 63 percent below its launch price. That's less than people ask for the 14-inch with the weaker 10-core chip, which starts around $1,099. The reason is secondhand logistics: big laptops sit longer and sell cheaper. For anyone who wants maximum graphics for minimum money, the 16-inch is currently the best deal in the Apple silicon lineup.

The M4 story runs the other way. The cheap option is gone: Apple stopped taking orders for the $599 Mac mini on April 22, 2026, pulled the configuration on May 1, raising the floor to $799, and in September replaced the line with M6 and M5 Pro models. The iMac 24 is what's left new at retail: the ten-core version with 16 GB and 256 GB is $1,699, with 512 GB $1,899, with 24 GB of memory $2,099. That's $200 above the launch price after the June increase. Apple sells the refurbished 14-inch M4 MacBook Pro for $1,359.

Competitors and alternatives

MacBook Pro 16 with M2 Pro at $933 to $1,100. More graphics, more memory bandwidth, and more screen than anything with an M4 at this money. The price you pay: a worn battery, seller warranty only, no hardware ray tracing, and macOS support that ends sooner.

iMac 24 with M4 at $1,699. The only new computer with this chip and the worst buy here. It hasn't been updated since October 2024, costs more than at launch, and a replacement is expected before the end of 2026. In graphics it loses by half to a three-year-old laptop that costs half as much.

MacBook Pro 14 with M5 at $1,599. The only way to get both the single-core speed and the graphics: the ten-core M5 GPU scores 11,614 in Wild Life Extreme, landing between the 16- and 19-core M2 Pro, plus hardware RT and 17 percent more multi-core than the M4.

Mac mini with M6 at $899, shipping September 22. A sensible replacement if you want a new desktop Mac with a warranty rather than a refurbished one.

Refurbished M2 Pro Mac mini. The 12-core version turns up less often than the 10-core and costs more, but it's still the cheapest route to 200 GB/s of bandwidth in a quiet box.

Verdict

The M4 beats the 12-core M2 Pro at exactly two things: single-core responsiveness, by more than 40 percent, and power draw. Everything else is either debatable or goes the other way. In graphics the M2 Pro leads by 42 to 53 percent; in multi-core the result swings from 24 percent behind to 13 percent ahead depending on the test.

Both have headroom for editing, development, photo work, and office tasks. Their ceilings differ: the M4 hits the wall on graphics and on 120 GB/s with local models, the M2 Pro on single-threaded work and the missing RT block.

On the used market the 12-core M2 Pro makes sense up to $1,100 for a laptop and $800 for a Mac mini. Above that, pay for the current platform instead: the refurbished M4 MacBook Pro at $1,359 comes with an Apple warranty and will stay supported two or three years longer.

Buying a new M4 machine today only works in one case, and that case is not the iMac. At $1,699 an all-in-one with two-year-old silicon and a 256 GB drive loses to both the new M5 MacBook Pro at $1,599 and a three-year-old 16-inch M2 Pro MacBook Pro at a third of the price. The first is faster at everything; the second is faster at graphics and far ahead per dollar.
