Thank you for shedding light <3
No, the 7870k doesn't have an onboard GPU. Thus less memory cache being used.
The benches might be skewed by only utilizing 4 cores?
This report is incorrect, It shows the 7870k beating the 8350 in every benchmark but they still go with the 8350?
I'm absolutely glad to hear that! I thank you as well, for your very kind words.
Guys like You makes me have a little more hope in humans. Thanks for being awesome mate!
Yes, I agree. This site is a nice reference, although comparisons can be misleading at times; it ultimately depends on your needs. Despite this, it seems like people just love accusing this website, along with GPUBoss, for being "Intel-biased", or "Nvidia-biased". Their results may not always be perfect, but this website is still a very useful reference. Don't shoot the messenger; it is what it is, and that's what it is. Remember, people; if you despise this website, you can simply cease your use of it.
this site is not BS it is the best for comparing cpus
Trying to find a addon for chrome to block cpuboss and similar BS sites from search results.
Wow great comparison and benchmarks, thank you very much as for this unbiased report!
