Reviews Word on the street for the Intel Pentium G620

While it's not a super high end quad core, nor does it support HyperThreading, this thing is probably the best bang for buck CPU on the market right now for Office work and moderate/heavy multitasking.

What People Are Saying Give it to me straight

Socket Type

For example if you break down the performance to the street price you get ~0.87 FPS per dollar that you spent on the Intel Pentium Processor G620.

Here is a CPU-Z v1.58 screen shot of the Intel Pentium G620 to see what we are going to be overclocking.

Legit Bottom Line: The Intel Pentium G620 is a dual-core processor with a stripped down 32nm 'Sandy Bridge' processor that is aimed at entry level desktop PCs.
by Legit Reviews (Aug, 2011)


The Intel Pentium Processor G620 costs $73.87 shipped and for the price it does fairly well considering it scored 64 FPS on the first pass and 11 FPS on the second pass.
by Legit Reviews (Aug, 2011)
Benchmark Results:The Intel Pentium G620 is a 65W TDP processor, but the highest Wattage that we were able to get the entire test system to was just 56.1 Watts.

Benchmark Results: When it comes to multi-core performance the Intel Pentium G620 was the only dual-core processor with no Hyper-Threading in the group and the performance wasn't enough to keep up with the other processors.
by Legit Reviews (Aug, 2011)
Pros: Speedy performance, Great value, Stays VERY cool, rock solid stabile, Onboard graphics are GREAT for HD movies.

Benchmark Results: The Intel Pentium Processor G620 does not feature Intel Quick Sync Video and as a result wasn't able to run this benchmark with acceleration enabled.
by Legit Reviews (Aug, 2011)


The Intel Pentium G620 didn't fare too well on this benchmark since it is a dual-core 2.6GHz processor without Hyper Threading technology.
by Legit Reviews (Aug, 2011)
With a 700MHz higher clock speed you'd expect the Intel Core i3-2120 to perform better than a Pentium G620, but that was not the case.
by Legit Reviews (Aug, 2011)
At an idle the Intel Pentium G620 used a little more power than the Intel Core i3-2120, which is strange, but not two processors are alike and power efficiency varies widely.

I've had multiple different applications open at once and found that she just keeps on chugging along.
by coachmark2 (Nov, 2011)
The Intel Pentium G620 has identical gaming graphics performance as the Intel Core i2-2120 that costs nearly twice as much.
by Legit Reviews (Aug, 2011)
One thing that we noticed is that the Intel Pentium G620 had the same gaming performance as the Intel Core i3-2120.
