ryzen performance underwhelming for gaming

[ChrisL333]

how much if at all do you think issues with bioses as well as ram and other technical issues have affected ryzen performanc3e. im seeing wildly different results from various reviewers

 

also how much performance do you think ryzen will eventually have in a month or so when the dust settles

There's already countless threads about this. No need for another one - just reply to one of the other 9001 threads.

Should start a new forum section for "Ryzen is bad for gaming !!1!1!!!!"

Or maybe it's just because of the relatively low clock speed compared to the 7700k which is what's causing it to lag behind in gaming.

lol sorry i was on my phone and scrolling kind of sucks

A low clock speed is certainly one factor, but there's definitely more going on than just that:

Probably the other issue with L3 cache latencies caused by having the two separate 'modules' (all the cores + L3 cache) merged together on one die, and when other has to access the other's L3 cache, it has to go through the memory controller which only has a bandwidth of 22GB/sec (which is apparently slow).

The i7-6900 series is clocked lower than the i7 mainstream processors and yet it keeps up with it.

Due to higher IPC and lack of the L3 cache latency issue (probably).

By AMD's own admission, single-threaded performance should be 19% worse than Kaby Lake while using stock clock for both.  If they admit to a 19% deficit, I think we all know it's quite a bit higher.

 

Time stamped for single-threaded performance talk with AMD:

I personally think the 8core/16threads aren't for gaming, they're for production.

 

the sweet spot for gaming is their 4c/8t or 6c/12t cpus coming in the future.

"production" these days in done via CUDA/OpenCL acceleration on the GPU

so, buying a expensive CPU that won't be used doesn't make sense

The ones based on the same architecture as Ryzen R7?

 

What do you expect to change in gaming performance when they cut 4 cores?

Take a look at the rest of the graphs in the link, though. Hitman was one of the worst for the 1800X, but it came within just a percentage point or two of the 6900K in some of the other tests. Including several that clearly favored the 8-core chips. Sometimes they're nowhere near 19% apart. So I'm not sure it's just IPC, either.

 

My point in my previous post was just to refute the implication that the low clock speed was the only or even the most important issue with Ryzen. Whether by IPC, cache differences, the SMT implementation, game optimization, or a combination of all of the above it's clearly a much more complicated situation than that.

90% of the 7700k's gaming performance and 90% of 6900k's productivity performance at half the price of the 6900k.

 

"Underwhelming"

The 7700K is cheaper though....

[PCGuy_5960]

That is to be expected... IPC is not on par with Boradwell:

More like 80% or less of the 7700k gaming performance.  Overclock both and that percentage drops even more.

 

Yes, a bit underwhelming when you look at the title of this thread.

Do we really care about 20 bucks? Not when looking at a 300 dollar CPU. We care about performance, and if you don't think 20fps matters. Run a 144hz monitor. 

 

Ryzen is Ryzen. Remove cores and not much changes. Broadwell-E and Kabylake are two different animals. Kabylake will eat the SR5 for lunch.
