Okay in terms of performance they go as follows.
1. 4790k
2. 4770k
3. 4790s
4. Xion E3-1230V3

The reason for this, is that the 4790s is a low power CPU...

The 4770k is. But the 4770k sells for the same price as the 4790k which is even better. The 4790s is quite cheap at the moment ($195 on newegg) so if you don't want to spend $300, go for it. If you want to spend $300, go for the 4790k. The only time to consider the 4770k is when you get it for $250 or less.

Wow so the 4770k is more powerful and better than 4790s.

Oops I thought the "4790s" was a type-o at first, or else I could of been more clear. Sorry about that. The 4790k is faster with better cooling, the 4790s is slower. Most people have been buying the 4790k if they are overclocking.

If you don't want to overclock and want to save money,

Get this Xeon CPU. Its a lot cheaper and it is just a little slower than the 4770k.

So your saying the 4770k is better than the 4790s? The 4790s is weaker than 4790k and 4770k. I thought the 4790s was stronger than 4770k.

The reason for this, is that the 4790s is a low power CPU. Its only a 65w TDP while the 4770K is an 84w TDP and uses much more power. The 4790s at stock has better single threaded performance at 4Ghz, compared to the 4770ks 3.9Ghz, and as a result might have slightly higher performance in some situations by 100Mhz. However, the base speed of the 4790s is 3.2Ghz and the i7-4770k is 3.5Ghz, which means if the CPU is running hot or there is a lot of heat in the case or something and it won't turbo and then the i7-4770k is going to be faster by 300Mhz.

On top of that, the i7-4770k can be overclocked and usually can reach 4.2Ghz easily which will make it faster than the 4790s in all situations, and that is a pretty low weak overclock.

The 4790s's Max TDP 65 W "S" indicates that the processor is using less power.

If you buy an good aftermarket cooler and do well in the silicon lottery than you might be able to overclock the 4770k to 4.7 ghz or more which will make it more powerful than the 4790s...

The 4790s is certainly weaker out of the box than the 4790k.

We would need to confirm however when all four cores are being fully utilized the 4790s will be down clocked even if the temperature is low.

You cannot guarantee that at all. Typically the Turbo speed drops 100Mhz for each additional core, down to the 3rd core and then doesn't drop for the 4th core. So the 4790s for example would be 4Ghz single thread, 3.9Ghz two threads (using two cores at full speed), 3.8Ghz with any additional threads and cores maxed.
However, some motherboards by default will run all of the cores at 4Ghz regardless of how many are active.
Then if the temperature gets too high, it will either drop a core or two so as to allow heat to maintain the 65w TDP limit, or limit the entire CPU down to 3.2Ghz. If the temperature stays low enough then the speed will keep stay at the turbo speed.

So there is a lot of other things that need considered also, not just the CPU.

The 4770k follows the same rules. with it being a max turbo of 3.9Ghz, 3.8Ghz, 3.7Ghz depending on number of cores being used. So it isn't accurate to say that the 4770k gives you a constant clock speed, or a clock speed that is always higher. It does use turbo boost technology. However, because its TDP is 84w it will have an easier time maintaining that speed without pushing past its thermal limitation.

You can disable turbo boost and set all cores to a constant 4.0 or more with a 4770k than it would be accurate...

" Aftermarket cooling and a decent 4770k would be required"

Perhaps I wasn't clear above

Well that is a little more accurate in that it won't run at a lower speed because of heat, but as a safety measure its usually best to use turbo boost. You are right that needs better cooling too but that all depends if he is comfortable overclocking. You get a lot of value out of unlocked processors usually but some people don't know how to make good use of them.

Looks like nobody paid attention to my post which is still correct: at stock the 4790S is the better choice and better value. Only if you overclock is the 4770K superior. In other words, if you're not overclocking it's not worth paying the extra money for the 4770k. Those were the two you asked about, that is the answer.

Don't complain just because you didn't get your post picked for the best answer.
Not to mention, your post is technically wrong. Only when the 4790s can maintain its max turbo speed is it better and the 4770k is not overclocked. If they were both put into an hour long stress test eventually the heat would build up and the 4790s would lower down to 3.2Ghz because its limited to a 65w TDP. Turbo boost only works when the CPU stays under the max TDP. The 4770k has an 84w TDP and will most likely not hit that limit even after an hour long stress test so it will stay in its turbo mode. Even if it did hit its 84w TDP limit, it would lower down to 3.5Ghz which is quite a bit better than 3.2Ghz and then it is faster. Not to mention in about 5 minutes after overclocking even a novice could increase the CPU to 4.2Ghz and then it will be faster over all.

So you are wrong because:
1. The 4790s isn't always faster than the 4770k at stock.
2. The 4790s is significantly slower when given even a very light overclock.

It has now been solved, no further posts or discussion needed.
