Intel Core i7-11700 vs Intel Core i5-11400T

Intel Core i7-11700

The Intel Core i7-11700 is a high-end desktop CPU based on the Rocket Lake architecture. The CPU offers 8 cores and 16 threads clocked at 2.5 - 4.9 GHz. The TDP is rated at 65 Watt (PL1, power limit sustained load) but the PL2 is set to around 224 Watt for short term boosts (up to 56 seconds).

The Sunny Cove processor cores (known from the Ice Lake mobile CPUs) offer larger caches and an improved IPC (up to 19%). Furthermore, the chip also includes (partly) integrated WiFi 6E and Thunderbolt 4. The platform supports PCIe 4.0 and Intel DL Boost for AI acceleration.

The faster Rocket Lake-S CPUs also integrate a new Intel UHD Graphics 750 that is based on the current Intel Xe architecture (e.g. mobile Tiger Lake).

The CPU is manufactured on the old 14 nm process like the Comet Lake predecessors.

Intel Core i5-11400T

► remove from comparison

The Intel Core i5-11400T is a power-efficient six-core desktop processor based on the new Rocket Lake architecture, which was introduced in March 2021. The processor clocks with a base clock of only 1.3 GHz and reaches an all-core boost of 3.7 GHz under load. Intel also gives the Rocket Lake processors the Hyperthreading feature, which allows the i5-11400T to process up to 12 threads simultaneously. As known, the Intel Core i5-11400F is manufactured in the 14 nm process. Nevertheless, many changes have been made with the Rocket Lake architecture, which is also reflected in the performance compared to the Comet Lake.

Performance

Compared to the Intel Core i5-10400T, the Core i5-11400T offers a significantly better IPC. This can be seen clearly in the single-core benchmarks. The multi-core performance also benefits from the better IPC compared to Comet-Lake. A performance increase of up to 20 percent can be expected.

Graphics

The processors integrates a Intel UHD Graphics 730 iGPU that features 24 EUs clocked at 350 - 1200 MHz.

Power consumption

The TDP turns out relatively low with 35 watts. This is the PL1 value. For Turbo, the Intel Core i5-11400T offers a higher TDP of up to 84 watts with PL2. However, this may only be applied for a maximum of 28 seconds (dew).
