12 core Core i7-12700F benchmarks

Puget benchmarks again :-(

Core i9-12900K price will be $699

This chip will have a 3.2GHz operating frequency, capable of 5.2GHz in Turbo Mode, with 16 cores and 30MB of L3 cache. As expected, the specs reveal it also supports DDR5 memory, PCIe Gen 5, and the Intel Z690 chipset motherboards that should go on sale at the same time.

Alderlake P will have up to 14 cores

Some benchmarks

Sources confirm that Intel's 12th Gen Core processor lineup, along with Z690 motherboards, will be available on November 19.

Very big power consumption

The Chinese portal FCPOWERUP, shared interesting information, taken, apparently, from Intel documentation for power supply manufacturers. It describes the power supply requirements for systems based on the new 12th Gen Intel Core processors, and specifies the constant and peak power values ​​that the PSU must supply over a 12-volt power line for stable operation of Alder Lake chips with different TDP levels.

The documentation lists the requirements for processors with TDPs of 165, 125, 65 and 35 W. At the moment, there is no confirmation that Intel is going to use a hybrid architecture in HEDT processors, so chips with a TDP of 165W may not appear on the market at all. It is more important to pay attention to the requirements for processors with different power consumption indicators.

While the current requirements under continuous loads for 12th Gen Intel Core chips generally remained at the same level as for the current 10th and 11th Gen Core models for the LGA 1200 platform, the requirements for peak current values ​​have increased markedly ... For Alder Lake models with a TDP of 125 W, the PSU should supply a maximum current of 39 A (468 W) on the 12-volt line in short-term mode, and not as before 34 A (408 W). For models with a TDP, this value increased from 30 A (360 W) to 38.5 A (462 W). And even the energy efficient 35W TDP models require the PSU to be able to deliver 20.5A (246W) peak loads. Thus, for 125-watt Alder Lake models, the required power supply of the PSU increased by 15%, and for models with a TDP of 65 and 35 W - by 28 and 24%, respectively.

This means that problems with the use of Alder Lake-S chips in theory can arise in systems that use old PSUs with multiple power lines (Multi-Rail). In these, the current on each individual line is typically limited to 20 A.

Coming in Q1 2022

On mobile ones

• Intel M5 – 5W-7W chips for tablets with Lakefield-like 1 big + 4 small core designs and 48 or 64 GPU execution units
• Intel U9 – 9W – 15W chips for ultra-thin laptops including 2 big + 4 or 8 small cores and 80eu or 96 eu graphics (there may also be a 1 big + 4 small + 48eu chip in this range)
• Intel U15 – 12W/15W/20W mainstream laptop chips with similar properties to the U9, but higher power consumption (and presumably higher clock speeds)
• Intel U28 – 20W – 28W “performance” chips with either 4 big + 8 small or 6 big + 8 small cores and 96eu graphics
• Intel H45 – 35W – 45W “thin enthusiast” chips for gaming laptops and workstations with 4 big + 8 small or 6 big + 8 small CPU cores + 96eu graphics
• Intel H55 – 45-55 watt processors with 8 big and 8 small cores + 32eu graphics, likely because these chips are designed for “muscle laptops” where they’ll be paired with discrete graphics (there may also be a 4 big + 8 small core version)
