Intel has doubled the number of Tiger Lake cores

For those familiar with Intel’s nomenclature, the “H” suffix, with which the chip maker has distinguished its high-performance mobile processors for many years, may be eloquent. This only means increased clock speed or power consumption for some designs, but a different slide design for others. Tiger Lake-H (or TGL-H) is bolstering the latter camp, as Intel has been forced to produce a second version of the chips hundreds of millions of dollars due to AMD’s recent rise.

The Cezanne, introduced by a competitor in January, has room for eight processor cores like its predecessor Renoir, which in many cases has proven scarcity of the quad-core Tiger Lake-U. This is the main reason for the birth of the octa-core “H” version announced today, which Intel intends to use mostly for high-performance 14-17-inch laptops. In addition to DTR (desktop replacement) work machines, this also means increasingly common gaming configurations, in which PC manufacturers typically build some type of discrete video card.

Intel has reduced the size of the Tiger Lake-H’s integrated GPU by a third, partly due to the latter and its smaller chip size. That means 32 graphics executives (EU) instead of 96, or significantly more modest performance. The additional four Willow Cove cores, along with the related Level 3 cache, were placed in a portion of the space cleared by the manufacturer. With this, TGL-H provides six or eight processor cores and 12 or 24MB of L3 cache, respectively.

Intel first announced five consumer and five commercial models based on Tiger Lake-H. Among the consumer models, the octa-core Core i9-11980HK is the top, with a base range of 2.6 GHz and a maximum turbo between 4.5 and 5 GHz with a 45-watt TDP. The commercial variant, Core i9-11950H (or Xeon W-11955M), has the same parameters, the only difference being the 35W TDP capability, which in turn reduces the core clock signal to 2.1GHz. The commercial models also handle ECC memory as well It recently announced protection against cryptojacking It can also be activated, which is a prerequisite for vPro.

Tiger Lake-H processors support the PCI Express 4.0 standard, which can be exploited with a total of 20 lanes. Hardware acceleration is also supported for Thunderbolt 4 and AV1 encoders, which in some cases may be an advantage over AMD Cezanne processors. Interestingly, unlike Tiger Lake-U, the “H” variant does not support low-power LPDDR4 memory, so OEMs can only attach the most popular DDR4-3200 chips / modules to the new processors.

In its own measurements, it compares Intel Tiger Lake-H to Skylake-based Comet Lake-H. According to the manufacturer, a 19 percent advantage on the same watch and base number in this combination can be a feature. Intel notes that for AVX-512 optimized implementations, the difference could be greater, up to 24 to 75 percent, depending on the code. The chip manufacturer claims to have already shipped 1 million units of various Tiger Lake-H models to OEMs, which will release over 80 different configurations in the coming weeks and months.
