Core i3 microprocessors add support for Hyper-threading feature, that allows them to execute twice as many threads at once. The i3s are generally clocked higher than the Pentiums, and they have GPU upgraded to HD 4400 on the i3-41xx series, and to HD 4600 on the i3-43xx series. The CPUs also support more advanced AES and AVX/AVX2 instructions. Low power Core i3-4160T and i3-4360T run at 3.1 GHz and 3.2 GHz, and have 35 Watt TDP. Standard power Core i3-4160 and i3-4370 operate at 3.6 GHz and 3.8 GHz, and they fit into 54 Watt thermal envelope. All Core i3 models have the GPU clocked at 1.15 GHz, and they support DDR3-1600 memory. Core i3-4160 and i3-4160T have the official price of $117. The Core i3-4360T and i3-4370 are more expensive, and they are priced at $138 and $149.
