Does Core i7 4820K outperform Core i7 4770K

Hopefully this question is not dumb because obviously 4820K is a greater number than 4770K and according to some benchmarks it actually does outperform it.

What confuses me is that Core i7 4770K is built using newest Haswell architecture while Core i7 4820K is built still on Ivy Bridge architecture. Price difference is almost none so that does not hint me anything really.

Yes 4820K is a greater number hence shall be a slightly more powerful CPU, is it in fact though?
 
Most of the time, no it does not perform better than the 4770. The times that it does are those where the quad channel memory gives it the edge, such as in video editing.

I wouldn't focus too much on the numbers, if you do you start assuming that the new low end hardware is better than the previous generation's high end hardware. An Nvidia GT610 doesn't outperform a GTX580 just because 610 is a bigger number than 580, it is all to do with the naming syntax.

Generally speaking, first number = generation, and it will generally go up one at a time. Intel 2xxx (Ivy Bridge), 3xxx (Sandy Bridge), 4xxx (Haswell), after that it is a free for all where you are better off looking at benchmarks. There are the exceptions in the naming pattern, like the one mentioned in this thread, which is down to either poor judgement or the companies trying to cash in on people's lack of understanding.

I see, well I got confused over the architecture used in those CPUs. I though the 4770K is going to be slower since its built on an Ivy Bridge architecture.
 
2xxx is Sandy Bridge, 2nd generation.

3xxx is Ivy Bridge, 3rd generation.

4xxx is Haswell, 4th generation.
 
There is almost no difference in performance between haswell and ivy in the current apps/benchmarks. I think the i7 4820k is even faster because it has an higher clockspeed.
But when more programs start to use the new instruction sets from haswell like AVX2, haswell will be very fast.
 
Well I think it depends what you want to use your PC for. For gaming, both the 4770K and the 4820K are overkill and an i5 4670K is more than enough. By getting an i5, you could spend more on your graphics card which is what matters most for gaming.

I am assuming this is for your future rig, the one which are also asking what graphics card to use?

I dunno. 5 years back I got Core i7 920 clocked at 2.66ghz and I kind of regreted that decision because it felt that the CPU was bottlenecking my Radeon HD4870X2. Reason was to safe money.

I dont wanna go that way again. Core i5 might save me up to 150 dollars however the leap between R9280X and R9290X is going to be 400 bucks at least isnt it.
 
The i5 won't be bottlenecking the 280X at all in the vast majority of games out there. Very few games benefit from the extra power of the i7. Really, the i5 is the ideal gaming CPU. For more advanced stuff like rendering, sure the i7 is a good choice, but the i5 is still good at that stuff too. I do video and photo editing on my i5 2500K and that's almost 2 years old now.

I kind of doubt that your CPU was bottlenecking your 4870 X2. I'm not sure how good the scaling on those 4870 X2s were anyway (since they were dual GPU cards), so if you were getting bad performance in games, that could have more of a GPU problem than a CPU problem. The i7 920 is still a very capable processor to this day and wouldn't really bottleneck most cards on the market.

If you bought the i5 and 280X, you could have some money to save for a rainy day or something. ;) Just because you have a lot of money to spend doesn't mean you need to spend it all. Why spend money on hardware that won't make much difference just for the sake of spending money on it?

I see. Well I didnt know that. Its always nice to save a buck. I will take a look at the Core i5. Any in particular I shoud check out?

For now I was going to go with Core i7 4770K so I would like to choose something of similar grade...
 
Yeah you want the i5 4670K. Just as overclockable as the i7 4770K and works with the same socket 1150 motherboards. Make sure you get a Z87 board - the Gigabyte GA-Z87X-OC would be a good choice for you. :good:

Yup I was just checking out the i5 4670K. So the major difference to i7 is the hyper threading right?

And is it true that games dont really advantage from hyper threading?

Thx for the advice on MoBo btw

Yes and yes. Really, the i5 is all you need and more for gaming. It's the graphics card which matters most when putting a gaming system together.

With a few cuts here and there I am beginning to feel more comfortable going for the R9 290X or the GTX 780 whichever benchmarks better.

Yeah, get one of those if you like, but if you intend on keeping that 1080p monitor I would probably just get the 280X or maybe the 770 (they perform very similarly anyway). At 1080p, either one of those is more than enough.

But if you intend to go bigger, then you'd benefit from the 290X probably.

1080p seems like a still good enough resolution for a while but who knows whats it gonna be in a year or two.

Thanks for help btw, really appreciate it a lot.
