After one year of being sold on the international market, ASUS is finally releasing its ASUS Transformer Book TX300 in the U.S. Set to be released on May 21,  this new hybrid notebook tablet goes up against two upcoming hybrids from HP.

HP is expected to release the HP Slatebook x2 and the HP Split x2, two hybrid tablets that promise functionality and speed. The Windows 8 ASUS Transformer Book TX300 features a 13.3-inch display just like the display found on the HP Split x2, which also runs Windows 8.

If you're in the market for a larger hybrid, you may be torn between choosing the highly anticipated ASUS Transformer Book TX300 of the HP Split x2 which is set for an August release. When you analyze the CPU hardware specs of each device, both feature Intel's 3rd generation quad-core processor. The ASUS Transformer TX300 comes with either the Intel Core i5 or i7 and the Split x2 has a choice of either the Intel i3 or i5 CPU.

The largest significance between the CPUs is between the Intel i3-3217U and the i7-3517U. Although ASUS didn't specify the clock speed, for comparison purposes, we can analyze an Intel i3 CPU commonly used by ASUS.

Where higher numbers indicate better performance, for the ASUS Transformer Book TX300, an Intel i3-3217U clocked at 1.80 GHz resulted in a CPU benchmark score of 2,281. An option for the HP Split x2 hybrid is the Intel i7-3517U CPU clocked at 1.90 GHz, which had a score of 3,794, Lastly, the CPU option for either hybrid, the Intel i5-3317U CPU clocked at 1.7 GHz had a score of 3,114. The performance differences between the i5 and i7 are slight, but the i3 shows a much lower performance than both of the CPUs.

The ASUS Transformer Book TX300 and the HP Split x2 hybrid notebook tablets are capable of supporting the heavy applications of the Windows 8 operating system. The benchmarks results suggest that the HP Split x2 with with an i7 processor resulted in better performance.
