Intel Tiger Lake-B, new BGA CPUs for PC SFF and enthusiast range

It is completely normal for some models of laptop CPUs to end in the desktop PC OEM market, in some cases this means that these desktop PCs inherit the limitations in terms of expansion and improvement that there are in laptops. One of the integration problems being the use of parts welded to the board, such as the use of CPUs that do not use sockets, as is the case with these Tiger Lake-B.

Tiger Lake-H comes to desktop PCs

In total, four new chips have appeared within the 11th generation Intel Core desktop family. The difference with those who have released so far? They will not be based on Rocket Lake-S, but on Tiger Lake-H.

Unlike what AMD has done with the transfer of its Cezanne architecture SoCs to its AM4 socket, Intel has not made a version for LGA1200 of Tiger Lake-H, since the new processors will use a BGA package. Which means that the CPUs are soldered to the motherboard and cannot be expanded.

To differentiate these CPUs from the Tiger Lake laptops they have been dubbed Intel Tiger Lake-B. These are also versions of these processors designed to be used under a higher TDP than the already known 15 W, 35 W and 45 W versions for laptops, since this time the new processor would have a TDP of 65 W taking advantage of the greater margin for consumption and heat than a desktop computer.

These are the four models of the Tiger Lake-B

Tiger Lake-H

In total, four CPUs from Intel’s new Tiger Lake-B range have been presented, their specifications are as follows:

  • The Intel Core i9-11900KB It is the most powerful of the range with an 8-core CPU and 16 threads of execution. Its base clock speed is 3.3 GHz, but it can go up to 5.3 GHz. Its TDP? 65 W.
  • Second we have the Intel Core i7-11700B, which has almost identical specifications, only with a base clock speed only 100 MHz lower, standing at 3.2 GHz.
  • If we go to the settings of 6 cores and 12 threads of execution, then we have the Intel Core i5-11500B with a 3.3 GHz base speed and 5.3 GHz maximum. Which translates into a higher clock speed achieved than the Rocket Lake-S.
  • To finish we have the case of Intel Core i3-11100B, which is a 4 core CPU with a 3.6 GHz base speed and 5.3 GHz turbo. It is surprising by the fact that Tiger Lake-H does not have a 4-core version.

Otherwise, the new Tiger Lake-B have the same specifications as the Tiger Lake-H. It has to be added that since the CPU is soldered to the board, we are going to see these CPUs in some pre-built PC models, although at the moment we do not know which ones.

The fact that Intel has opted for a BGA version of Tiger Lake-H for the desktop makes us think that Intel is no longer manufacturing CPUs under its 14nm node and that it has already made its transition to its next node. Which makes sense when you consider that these Tiger Lake-B and future Alder Lake-S are manufactured under Intel’s own 10nm SuperFin node.
