Alleged Intel Tiger Lake-U 10nm CPUs Show Strong IPC Performance In Leaked Benchmarks

Intel Wafer
Intel must be getting somewhat close to launching its next-gen Tiger Lake CPU architecture and product lineup, because the leaks keep rolling in at a sometimes frenetic pace. Just last month, for example, benchmark entries for Tiger Lake-Y processors sporting Xe graphics were spotted in both Geekbench 5 and SiSoftware SANDRA. Now just a few weeks later, Tiger Lake-U is making a cameo in Geekbench 5's database.

Tiger Lake is being built on a 10-nanometer process node, and based on past roadmaps, are not expected to launch until the second half of 2020. It's not clear if those plans have changed, however, with all of these early entries we are seeing. Either way, we are looking at a successor to Intel's current Ice Lake lineup.

As we wait, prominent leaker and Twitter user APISAK spotted a couple of Geekbench entries of interest, both supposedly representing Tiger Lake-U silicon. One of the entries shows the platform running with 16GB of LPDDR4 memory, while the other shows the chip paired with 8GB of DDR4 in SO-DIMM form (notebook memory, basically). Here's a look...

The benchmark run with Tiger Lake-U running alongside 16GB of LPDDR4 memory posted a single-core score of 1,189 and a multi-core score of 4,274, while the configuration with 8GB of DDR4 SO-DIMM memory posted a single-core score of 1,162 and a multi-core score of 4,047.

Both chips are listed as having 4 cores and 8 threads, with a 1.19GHz base frequency. That gives us enough data to compare with current-generation parts, and interestingly enough, these scores stack up quite nicely to what's available right now.

For example, the Core i7-10710U (Comet Lake-U, 14nm) sports 6 cores and 12 threads, and is clocked at 1.61GHz. Results are kind of all over the map, but if we look at this entry for a Dell XPS 13 7390, it shows the Core i7-10710U scoring 1,110 in the single-core test and 4,249 in the multi-core test.

Compared to Ice Lake-U, here's a listing for a Dell XPS 13 7390 running a Core i7-1065G7, and scoring 1,233 in the single-core test and 4,757 in the multi-core test.

We have no way of knowing if the Tiger Lake-U entries are legitimate, but assuming they are, performance will likely improve by the time it gets released to the public (especially if the platform makes the rumored leap to DDR5 memory). In the early going, however, Tiger Lake-U looks promising.
