These include the i9-13900T, i7-13700T, i5-13600T, 13500T, 13400T, and the i3-13100T and no one is really clear why they are late.
Chipzilla's 13th Gen T series CPUs are the lowest power-consuming processors with a 35W TDP. They are probably not the sort of chip you want to base a build around unless you want a small form factor chassis with little in the way of active cooling. T series chips are popular in prebuilt mini PCs such as Lenovo's ThinkCentre M Tiny series.
All models share identical cache, and core count configurations, but the clock speeds for both the P-Cores and E-Cores have taken a big hit due to the stricter power requirements. They will be pretty low on the buying list for CPUs for gaming or productivity.
| CPUs | Core Count + L2 / L3 Cache | Clock Speeds Base / Boost (P Cores) | Prices |
| i9-13900T | 24 (8+16) + 32MB / 36MB | 5.3GHz / 1.1GHz | $671 |
| i7-13700T | 16 (8+8) + 24MB / 30MB | 4.9GHz / 1.4GHz | $469 |
| i5-13600T | 14 (6+8) + 11.5MB / 24MB | 4.8GHz / 1.8GHz | $308 |
| i5-13500T | 14 (6+8) + 11.5MB / 24MB | 4.6GHz / 1.6GHz | $283 |
| i5-13400T | 10 (6+4) + 9.5MB / 20MB | 4.4GHz / 1.3GHz | $272 |
| i3-13100T | 4 (4+0) + 5MB / 12MB | 4.2GHz / 2.5GHz | $155 |
The Core i9-13900T and i7-13700T have a 300 MHz reduction in max turbo frequency compared to the i9-13900 and i7-13700, with max turbo clocks of 5.3 GHz and 4.9 GHz respectively. Base clocks are a GHz lower on the 13900T and 13700T at 1.1GHz and 1.4GHz.
To make matters worse, Chipzilla does not seem to think that gutting the performance of these chips worthy of a significant price drop. The chips hold identical pricing to their non-K brethren. According to CaseKing's listings, the i9-13900T comes in at $671, i9-13700T at $469, i5-13600T $308, 13500T $283, 13400T $272, and i3-13100T at $155.
