For comparison, Tiger Lake-H delivers up to 51.2 GBps of maximum memory bandwidth, while the B-series tops out at 45.8 GBps. However, the B-series seems to offer less memory bandwidth. Like Tiger Lake-H, the B-series also comes with native support for DDR4-3200 memory and a maximum capacity of 128GB. The iGPU and Tiger Lake's other features look untouched. It seems that Intel only made improvements to the processing aspect of the B-series. The Core i5-11500B is rated for 4.6 GHz boost clock, 100 MHz faster than a Core i5-11400H. For example, the Core i7-11700B has a 4.8 GHz boost clock speed, only 200 MHz higher than the Core i7-11800H. If we don't take TVB into consideration, the improvement is very little. Obviously, TVB gives the B-series higher boost clocks on paper. The difference is between 400 MHz to 700 MHz, depending on which models you're looking at.

Despite the Core i9-11900KB and the Core i9-11980HK having the same maximum 65W TDP, the first leverages TVB to boost to 5.3 GHz, 300 MHz higher than the latter.Ĭomparing from tier to tier, we're noticing higher base clocks on the B-series SKUs. The octa-core processor appears to feature a 3.3 GHz base clock, 4.9 GHz boost clock and 5.3 GHz TVB boost clock. The Core i9-11900KB is the only chip out of the lot that comes with an unlocked multiplier. The Core i5-11500B and Core i3-11100B have a fixed 65W TDP. According to the Intel's specification sheets, only the Core i9-11900KB and Core i7-11700B can be configured down to 55W. The 20W margin allows the B-series access to TVB after all, which can be a difference maker in certain workloads. Since the B-series all enjoy a 65W TDP, it's common sense that they are faster than Intel's recently announced Tiger Lake-H 45W processors. It would appear that the Tiger Lake B-series processors benefit from Thermal Velocity Boost (TVB), though. The Core i5 and Core i3 SKUs arrive with six-core, 12-thread and four-core, eight-thread setups, respectively. The Core i9 and Core i7 are equipped with eight cores and 16 threads, but with clock speeds as the main differentiating factor. The core configurations for the listed Tiger Lake processors stick to Intel's guidelines. There's a possibility that these processors are soldered to the motherboard via the BGA package. Nevertheless, the 'B' is rumored to BGA (Ball Grid Array), which makes sense since Intel doesn't specify a type of socket for the B-series parts. The product pages for the Core i9-11900KB, Core i5-11500B, Core i7-11700B and Core i3-11100B have the aforementioned processors as desktop chips. We're unsure of what the letter stands for.

However, they carry the 'B' suffix, which is a designation that Intel hasn't used until now.

The quartet of new processors are listed under the Tiger Lake family, with the 11th Generation moniker.
