Is one Intel core similar to two AMD cores?
2017-01-17 1:33 am
When each Intel core is hyperthreaded, it allows for parallel processing, so would that then make it similar to two AMD cores? Is this also why people prefer Intel processors, simply because it produces less heat because of less cores, but each of them are hyperthreaded so that 4 Intel cores would be similar to 8 AMD cores?

rigorous testing showed better gaming thruput with intel cpus.

Nothing like that at all and I don't think heat and power are an issue to some people. Also performance isn't a yes or no issue because of the way a program takes advantage of the processor. I believe people prefer Intel because their products have excellent single core performance that's much better than AMD's offerings. 90% of the people who ask these questions are looking to build a gaming computer and for them, because of the way a PC games and graphics card use the CPU. Intel is a better choice.
The 8 core Intel 5960x and 6900k don't use a lot of wattage. In fact, the newer 6900k uses about 93w at full load and at stock speeds puts out a manageable level of heat. the 125w TDP you see on these processors refers to Thermal Designed Power. Although, for the most part the wattage and TDP are usually close.
I'll tell you what Hyperthreading does and why it's useful. One way is You have to look at it in terms of task scheduling. The program can load information to the 2nd virtual core. Once the core is finished with the 1st string of information it can start working on the 2nd string without delay. That's just one way it works. Another way Hyperthreading works is it can process two simultaneous threads, just as long as the 2 threads are using a different execution units within the core. A normal CPU core has several different types of execution units and if the core is resigned to just one thread then much of that would go to waste.
Now, despite the contrary, it does help if the program is written to take advantage of Hyperthreading. Some programs will see a 5% speed increase and other will be in the ballpark of 35%. Up until recently there wasn't a PC game that was made to take advantage of more than 3-4 cores. This is why most gamers chose an i5 CPU.
When you look closely at the AMD 8 core FX processor, you'll find they really aren't 8 true cores. 2 cores share a module which shares resources and each 2 core module has 1 floating point scheduler. Word on the street is AMD designed the Bulldozer/FX processor for servers. However the board of directors at AMD thought it looked good for the mainstream and they banked on Parallel processing to be the wave of the future.

No.
Intel "hyperthreaded" cores consist of one actual computing core linked to two sets of registers.
The dual registers make it appear externally as two cores but the single actual core can only be running one or the other set of registers.
It allows fractionally faster task changes with a single level of storage, rather than needing the registers swapped to RAM at any change.
AMD dual-core "modules" each have two full integer cores and a shared floating point coprocessor.
They can run simultaneously for any form of integer code or floating point up to 128 bit. The only delay is if both try to process a 256 bit floating point instruction at the same instant, which is generally an extremely rare event.

They are two different creature entirely
Intel has a contact board and has pins one is better suited for speed ones more suited for prolonged work
