Modern CPU Instructions

[prince_xaine]

LGA 775 processors are lacking some modern instructions, such as AVX. I always feel people always neglect the instructions of a processor over the performance of a chip. I believe LGA 775 still performs well in gaming and general use - as long as it has the instructions capable of completing the task.

Are there any modern instructions LGA 1155 processors are lacking? Meaning - besides the speed of the processor and it's ability to complete a task quickly - are there any actual tasks it cannot do?

Thanks in advance!

Actually the difference is 5 years. The dates on the site are simply when they added it to their list. 2008 for the QX9770 and 2013 for the i3-2125

In comparison the best i5 it can match with is the i5-661, which is obviously no bueno.

i3 2125 was released Q3 2011. https://ark.intel.com/products/59080/Intel-Core-i3-2125-Processor-3M-Cache-3-30-GHz-
So about 3.5 years gap between the two.

Sorry guess I clicked the wrong link, either way that's not overclocked. That processor over clocked extremely well. Look at the best bench for the processor. 55%. That puts it near the top of the ivy bridge processors (not overclocked).

How do you figure? Something like an i5-3550 gets 68%, significantly better than the OC'd X9770. And that's mid-range Ivy Bridge.

Of course, this is all assuming that userbenchmark is a good way to compare CPU performance. I personally don't think it is, but it is convenient.

It's actually a really good benchmark. Not good for stress tests though. And I realized that almost right after I sent it. An i7-3770k is basically the best you can get without overclocking and is ranked at 73%. So there was no way that 55% could be high end. It would be in the bottom 25% - but that's good enough when paired with a 1050 Ti to run most games (that don't require extra instructions) to run at a stable 30FPS - which means you can easily build a system thats console level for much less.

Here is an example of my system with an overclocked i7-3770K overclocked to 3.7 GHz. https://www.userbenchmark.com/UserRun/13267855
