Ryzen 1800x vs i5 2500k on Lightroom?

LR is lagging quite badly on my 2500k with the a7r2 images even with smart previews and 1:1 previews.

was wondering, will upgrading to the new Ryzen or 6900k boost performance significantly?

is LR effectively multi-core accelerated? Their single core performance is not so far apart, even though the price is.

Lr depends more on single core performance than multi-core and will see very little performance gain beyond 4 cores for the tasks which use multi-cores(Exporting images to Disk in the one area where high core count really boosts performance). A higher clocked 4 core CPU will give more performance overall than an 8 core lower clocked CPU.

Have a look at some testing/benchmarks https://www.pugetsyste​ms.com …lti-Core-Performance-649/

I'm waiting on real benchmarks from reviewers before deciding on Ryzen.

I am going to say which ever is clocked is going to be the better chip for LR. Since from what I have seen both will have close to the same IPC. It's not the fault of Intel or AMD, it's how horrible adobe is at coding and optimizing for more cores.

Clock speed is largely irrelevant, but single core speed is most important for interactive Lightroom use. Take whatever processor gives you the best single core performance and provides at least 2 cores, ideally 4.

Batching out images scales reasonably well on cores. Multicore programming is very difficult, though Lightroom is lagging behind where it should be.

Amongst same generation CPU's the best single core performance will be the one with the highest clock speed. Currently the i7-7700k and i3-7350k sit at the top of PassMark CPU Benchmark for single threaded performance. The i7-4790K is actually faster in single thread performance than the i7-6700k because it has a higher turbo boost clock speed. Amongst Intel CPU's the newest generation will have the highest performance per core in synthetic benchmarks.

In real world performance newer generation CPU's may not show alot of gain over previous generations if the software you are using is not optimized for the Instruction Set built into the CPU and there wasn't a change in the manufacturing process(ie. going from 22nm to 14nm).

according to AMD the new Ryzen 1800x is faster than the i7 6900k which is a 1100 dollar cpu...
your outdated Sandybridge i5 is like 5 years old by now and IF the new Ryzen can't even beat that I Think AMD should start making burgers and coffee instead

It would seem like gaming and single core performance is not up to par with Intel i7-7700k which is cheaper - based off of the latest reviews.

Ah well. To #teamblue now.

Actions where you can process multiple images in batch can be sped up using multicore. However, I believe single image editing is still done one-image-per-core basis. Even if you have 1000 cores, its hard and unreliable to exploit multiple cores to perform actions on ONE image.
So your editing process won't be faster. Import and Export will be.

The problem is, most of those tasks that can use multiple cores do not scale very well beyond 4 cores, only exporting really utilizes multiple cores efficiently and it pretty much flat lines at 6 cores. Intel still has the performance advantage when it comes to Lightroom and Photoshop.

Or you could just wait for the next batch of 6 and 4 core processors from AMD which are slated for Q2... those are the ones that are meant to take on the i7's and i5's and are likely to hit that traditional low AMD price point.

As for the OP; If you haven't upgraded to an SSD yet for your OS and LR than I would start with that. I saw a much bigger difference when I switched to an SSD than I did when I switched from my 1090T to my i7 3820.

For gaming the 1100 dollar i7 6900K is slower than Skylake i7 6700K...
these 8 core cpus are not meant for gaming and I usually laugh at ppl for getting cpus with 6 or more weaker cores at considerably higher price than 4 core i5s and i7s

Indeed - my point exactly. Unless photography takes second fiddle to 3D and video content creation work - the 7700k might be the best bet from the blue camp now.

Yeah, but like I said, when the lower tier Ryzen stuff launches in a few months it'll shake up that market.

The stuff they just launched wasn't intended to compete with the 7700k, it was meant to take on the 6900k, which is also worse for gaming than the 7700k.

True, they do say that, but we are not starting to see some independent benchmarks. The new AMD chips are performing well, but I have yet to see one that in real world benchmarks is quite up to what they say. Not saying there bad, the chips look good. Great to finally see AMD give Intel some competition - been a long time. Also, looks like Intel is taking notice and prices seem to be dropping.

i read through some benchmarks and noticed that a 7700k is only 29% faster than a 2500k in single-core performance.

In addition, my 2500k can OC up to 4.8ghz with my custom cooler. Does it not make sense to upgrade based on LR alone then?

the image-to-image loading and editing in Develop (even with Smart Previews) is killing me.
