i7 6700k/i7 7700k vs Ryzen R7 1700 i dont know what to take

post #1 of 9
Thread Starter 
Hello guys,

I have been around these 3 last days deciding between i7 6700k 7700k and Ryzen R7 1700. Each day passes im more convinced of going to 1700 because of optimization and cores.

Thing is others tell me to go with 6700k/7700k.

I will be running on Corsair RAMS 16GB at 3200.

What should i take ? frown.gif i want gaming

It's pretty hard to suggest which one to go for atm. What games do you play? Are there major differences in benchmarks for those particular games ? That would probably play a part into which one I would go for.

Also, consider that a lot of the time there are problems with first gen releases- I almost always wait until at least the 2nd revision of something-- but not always.

For just gaming, Id suggest taking the 7700K, or saving the money and taking a Ryzen 5 1600x.

I'd say saving the money and putting it towards a GPU is going to benefit you more overall.

The 1700 is difficult for me to recommend in a pure gaming rig, the 7700K beats it and it costs about the same. With the 1600x you get almost the same performance as the 1700 and it costs less.

Performance on Ryzen will only go up. Performance on those two Intel CPUs will only go down. It depends how long you're looking to keep this system for. If more than a year or two, go RyZen. Heck, the RyZen 1600x might even be a better buy for ya.

For gaming pick the 7700k, performance of the 1700 in gaming will only catch up with the 7700k because of its low IPC, there is no such thing as performance going down for 7700k. @5ghz (avrage oc) the 7700k is uncontested. The argument that 1700 will increase in performance is true as more threads are being used in games but it is still limited by its low IPC which means the other thread cycle time still need to wait for the primary thread to be finished. People hype the more core/thread count but forget that IPC/single core performance is still important especially when there is a 35% single thread performance difference compering an 1700@4Ghz vs 7700k@5Ghz. This can even be seen on DX12 games that are more optimized for more threads the 1700 still loses. Buying a CPU based of what it could require cognitive bias to be happy.

35% is a bit much. 4ghz vs 5ghz is 20% performance gap roughly between Ryzen and Kaby. Kaby also has a 6-7% IPC advantage so worst case scenario Kaby is 25% faster in single threaded tasks. That's still a huge amount, just not 35%. Perhaps actual real world usage you can see 35% performance difference but thats going to be only in titles that use 2 threads where the Ryzen will really suffer. Lots of Blizzard games only use 2 threads. I think Overwatch is the only one that uses 4-6 threads.

Sorry mate but your math is wrong going from 4Gz to 5Ghz is an 25% increase in itself + exponentially adding the 7% = 33.75%. To further back my pint you can see on Cinebench one tread there is an exact 33.33% difference, Yes i was off roughly 1% but it is within margin of error.

What? 216/195 = 1.107, or 10.7% from stock 7700k @ 4.5ghz boost compared to a 5ghz 7700k which is what i assume that 216 score is and that would make sense since every 100Mhz OC is roughly 2% performance bump. So from 4ghz to 5ghz you're looking at 21.4% performance bump. Add the 6-7% IPC boost over Ryzen and you have 27-28% increased performance in single threaded. Cinebench is also a synthetic bench which will show best case scenario and that doesn't apply to gaming. You're not going to see a 25%+ performance difference in gaming, and the OP is asking about which CPU for gaming.

Now the short answer is get the 7700k, its the best for gaming, and that's a FACT. How much better is it in gaming? Well it depends on the game, and Ryzen is still young and many current games won't ever get Ryzen specific optimizations, but we can assume future games will and should perform relatively close to the i7. If you don't want to worry about varying performance differences with some games working really well with Ryzen while others are doing poorly then just get the 7700k.

I for example play WoW and Starcraft 2 from time to time and those two games only use 2 threads and will always only use two threads with their old engines. Because of this the 7700k will give you much better performance actually inline with the 25%+ single thread difference. Games that support 4 threads or more will have a much smaller gap between the Ryzen and Intel part in the range of 10%, sometimes less if there are no optimization issues.
