AMD Phenom II X4 840T: specs and benchmarks
AMD started AMD Phenom II X4 840T sales 1 September 2010 at a recommended price of $80. This is Zosma architecture desktop processor primarily aimed at office systems. It has 4 cores and 4 threads, and is based on 45 nm manufacturing technology, with a maximum frequency of 3200 MHz and a locked multiplier.
Compatibility-wise, this is AMD Socket AM3 processor with a TDP of 95 Watt. It supports DDR3 Dual-channel memory.
It provides poor benchmark performance at 2.56 percent of a leader's which is AMD EPYC 7763.
Of Phenom II X4 840T processor market type (desktop or notebook), architecture, sales start time and pricing.
Basic microprocessor parameters such as number of cores, number of threads, base frequency and turbo boost clock, lithography, cache size and multiplier lock state. These parameters can generally indicate CPU performance, but to be more precise you have to review its test results.
Information on Phenom II X4 840T compatibility with other computer components and devices: motherboard (look for socket type), power supply unit (look for power consumption) etc. Useful when planning a future computer configuration or upgrading an existing one. Note that power consumption of some processors can well exceed their nominal TDP, even without overclocking. Some can even double their declared thermals given that the motherboard allows to tune the CPU power parameters.
Supported virtual machine optimization technologies. Some are specific to Intel only, some to AMD.
Types, maximum amount and channel number of RAM supported by Phenom II X4 840T's memory controller. Depending on the motherboard, higher memory frequency may be supported.
Single-core and multi-core benchmark results of Phenom II X4 840T. Overall benchmark performance is measured in points in 0-100 range, higher is better.
