The 12700H is 36% faster than the 11800H here, and is now beating the Ryzen 7 5800H by 33%, up from a mid-20s improvement in the lower power class. Intel is able to extend its lead when looking in the 75W power class. But among the x86 pack, the 12700H does appear to be the best processor in terms of performance per watt in this workload. It's also 8% faster than Apple Silicon, though the M1 Pro uses a bit less power in this workload. This represents a 27% performance improvement over the Core i7-11800H, a 21% improvement on the Ryzen 7 5800H and a 12% gain on the Ryzen 9 5900HX. The Core i7-12700H is the fastest laptop CPU we've tested to date, beating all other contenders including the Ryzen 9 5900HX and Apple's M1 Pro, even when run at just 45W. We'll start with everyone's favorite, Cinebench R23 multi-threading. On to the results! Application Benchmarks If you're buying a thinner and lighter system, the 45W numbers will be most important, while those after a beefier system with more cooling power should look at 75W.

Boost PL2 power is set to Intel's default of 115W in both instances.Ĭonducting benchmarks in this way gives you the most useful information that can be applied to a wide range of laptops. If we compared one chip at 75W to another at 60W, we'd really only be comparing which specific laptop design can send the most power to the CPU, not which CPU actually performs better, which is why we test like this. These will be compared apples to apples with other laptop chips running at the same configuration, which gives us the best look at how these CPUs compare in a fair benchmark battle. Both models also pack 1440p high-refresh displays and 32GB of DDR5-4800 memory in a two stick configuration.įor testing the i7-12700H we've run two power configurations: a long-term PL1 power limit of 45W, Intel's default spec for these chips, as well as 75W, which is a common boosted power level seen across many laptop vendors. We'll be testing both of these GPUs at a later time.

The smaller GM5AG7Y 15-inch also packs the Core i7-12700H, but running an RTX 3070 Ti Laptop GPU at 125W. The GM7AG8M 17-inch chassis includes the Core i7-12700H and new GeForce RTX 3080 Ti Laptop GPU running at 150W. We can't tell if these specific ones will become XMG products, but other companies like Eluktronics use these sorts of laptops and you should see them available for sale soon. The two designs we have on hand should be widely used across various OEMs. Our test platforms for today were kindly provided by XMG and their partner Uniwill. We'll be checking out the 12900HK soon, but the 12700H could be hitting that value sweet spot. The 12800H, 12900H and 12900HK that sit above it are essentially just clock speed improvements, and in previous generations simple clock speed bumps haven't been a great value proposition for buyers.

The Core i7-12700H is the lowest chip in the stack that still provides the full complement of CPU cores found in Intel's H-series die, making it a compelling option. Like prior Intel products, the default TDP for this chip is 45W, though many laptop OEMs will have modes to enable higher long-term power limits. The P-cores are clocked at 2.3 GHz base and 4.7 GHz boost, while the E-cores get a 1.7GHz base and 3.5 GHz boost clock. The 12700H packs 6P cores and 8E cores for a total of 20 processor threads, along with 24MB of 元 cache and a 96 execution unit GPU. We expect the Core i7-12700H that we're reviewing today to become the most widely used chip in Intel's line-up, like the Core i7-11800H and Core i7-10750H before it, slotting right into a huge range of mid and upper-mid range gaming and productivity systems. Intel claims these new processors should be the fastest ever seen for mobile computing and we'll be exploring that later in our benchmarks. The Alder Lake H-series targets high performance laptops, while also bringing a range of new platform advantages, including DDR5 support, a beefier Xe integrated GPU and other connectivity improvements. This is our first look at 12th-gen Core mobile processors, starting with the Core i7-12700H.Īs we've discussed at length in our desktop Alder Lake reviews, this hybrid approach has been reasonably effective on desktop machines, but the dual architecture approach should really come alive in constrained form factors like laptops, where power consumption and efficiency are key. Alder Lake is Intel's first serious step into the world of hybrid architectures, combining a new high-performance CPU architecture (P-Cores), with smaller efficient cores also known as E-cores, for better performance and enhanced performance per watt.
