AMD Ryzen 3 3100 vs Intel Core i7-6700T
AMD Ryzen 3 3100
► remove from comparison
The Ryzen 3 3100 is a cheap entry level desktop processor of the Matisse series with 4 cores and 8 threads. It clocks from 3.6 (base) - 3.9 GHz (boost) and uses the Zen 2 microarchitecture. It uses two CCX clusters with two cores each. Therefore, there are some disadvantages compared to the faster Ryzen 3 3300X that uses all four cores of a single CCX-cluster. The CPU is manufactured on the modern 7 nm process at TSMC. The I/O die that is not part of the main die is manufactured on 12 nm at Globalfoundries. The TDP is 65 Watts and therefore the CPU won't need a big beefy cooler.
In multi-threaded applications the performance of the Ryzen 3 3100 can reach the old Core i7-7700K (a former high end CPU). In games and single threaded applications, the performance is slightly lower as the higher clocked Ryzen 3 3300X is on par with the 7700K. Still, the 3100 can be a good pick for an entry level gaming system.
Intel Core i7-6700T
► remove from comparison
The Intel Core i7-6700T is a quad-core processor based on the Skylake architecture, that has been launched in September 2015. It is generally intended for desktops but due to the relatively low TDP of 35 Watt is is also used in some laptops. In addition to four CPU cores with Hyper-Threading clocked at 2.8 - 3.6 GHz, the chip also integrates an HD Graphics 530 GPU and a dual-channel DDR4-2133/DDR3L-1600 memory controller. The CPU is manufactured using a 14 nm process with FinFET transistors.
Architecture
Skylake replaces both Haswell and Broadwell and brings the same microarchitecture in every TDP class from 4.5 to 45 W. The extensive improvements of the Skylake design include increased out-of-order buffers, optimized prefetching and branch prediction as well as additional performance gains through Hyper-Threading. Overall, however, performance per clock has been increased by only 5 to 10 percent (compared to Haswell) respectively under 5 percent (compard to Broadwell), which is quite modest for a new architecture ("Tock").
Performance
According to the specified clock rates and the improved architecture, the Core i7-6700T performs roughly on par with the former, somewhat higher clocked Intel Core i7-3770K (Ivy Bridge). Therefore, the CPU is also well suited for demanding applications.
Graphics
The integrated graphics unit called HD Graphics 530 represents the "GT2" version of the Skylake GPU (Intel Gen. 9). The 24 Execution Units, also called EUs, are clocked at 350 - 1100 MHz and offer a performance about 20 percent above the old HD Graphics 4600. Games of 2015 can thus be played smoothly in low or medium settings. For more information about performance and features, check our page for HD Graphics 530.
Power Consumption
Specified at a TDP of 35 W (including CPU, GPU and memory controller), the CPU is best suited for bigger notebooks 15-inches in size and above or small desktops.
