Please help me decide - Ryzen 7000 or Raptor Lake for productivity

[DiscoDave]

Hi all,

I have no interest in gaming any more - I use my desktop for work and do a bit of software development. I have been holding out for the Ryzen 7000 but have also seen the Intel 13th Gen processors on pre order.

Mobo prices for Z690 seem a bit more reasonable and I'm not sure I would take advantage of Z790. As long as the iGPU can power 2x 4K monitors, that's pretty much all I need.

Given that, which should I go for?

I'll be upgrading from a 6700k.

Thanks

I would have a look to see if any reviewer has done benchmarks on applications you use.

For example 12900K beats 5950X in some MT and looses in others, if you were rendering in VRay or Blender then the e-cores don't count for as much - 7950X is even more impressive in those now

I'd wait until the reviews, as far as I know, we just have a few benchmarks and I wouldn't want to order anything based on those.

 

[Kirby Wurm]

Definitely wait for Raptor Lake reviews first, and check the benchmarks for programmes you'll be using. Even between products that have relative overall performance parity it can vary greatly in specific applications.

Best to wait and see reviewer results. More of a real world view then manufacturer graphs/ claims etc

Wait for Raptor Lake it looks like it will compete well with Ryzen 7000, and at lower temperatures and a lower price.

Also Raptor Lake has power modes and from the information from Intel, one setting will set the 13900K to perform the same as a 12900K, but at just 65W.

and at lower temperatures and a lower price.

I know AMD says the new CPUs are totally fine and happy at 95 degrees... but I'm not sure I want that much heat dumped out the back of my PC. And it implies the internal case temps will not be great, if only because of thermal conduction around the socket. Nothing in there should be close to actual boiling point! D:

That said, not sure if CPU core temps directly translate to heat venting, or whether it's more the overall power draw.

It's the power draw primarily. In der8auer's delid video it looks like it's not getting out of the core efficiently (the temp dropped by 20 degrees C).

when it gets to 95 its not like the 'normal' 95 its like the hotspot on gpu, it's in a small area.

i watched a review where they talk about it. it was watercooled and the temperature dropped instantly it wasn't taking a while to come down which is what happens with aio watercooling, it's 95 degrees but a small area of 95 on the cpu.

not 'cooler' 95. but cpu small die 95,a bit hard to explain.

i'll see if i can find the video

This is fine...​

People are mistaking this 95 degree thing. The CPU is designed to run at 95 degrees and is a very small area inside the cpu, it doesnt have some crazy power output where it blows 95 degree air out of your case giving you 1st degree burns.

Think of it like a spark and a hot bath. A spark is several hundred degrees but very small and bath is only about 40 degrees but has much more energy.

For heating your room you are concerned with power consumption as that is where a lot of that is converted to waste heat, the same way electric heaters are rated in wattage not maximum temperature.

Couple important questions; what is the most CPU intensive software that you use and how many cores can it load simultaneously?

The answer to this will dictate which is probably best for.

AMD processors also have Eco mode. The 7950x in 65w Eco mode beats the 12900K at 240w in Cinebench!

Lower temperature of a very small part of the die is mostly irrelevant. Watts is what matters.

Efficiency of Zen4 is actually very good, but desktop Ryzen 7000s does seem to have been pushed a bit too far so setting it to 65W Eco mode will make a huge difference as @sparkymark75 already mentioned.

Ryzen 7600X and 7950X review: Zen 4 starts off expensive but impressive

Thermal behavior is a bit odd, but there’s lots to like about these new CPUs.

Yes, pity that ARS doesn't sort their charts.

Eco mode should reduce temps but at the expense of performance.
If I had spent £700 on a 7950X and had to reduce it to a 5960X for manageable temperatures I would annoyed, to say the least.

That wasn't my point though: even set to 65W the 7950X vastly outperforms the 200W+ 12900. At 105W it actually gains at Handbrake compared to 170W:

now it may be that the extra E cores on Raptor Lake will help massively in Handbrake and increase Intel's perf/watt, but for tasks where the E cores aren't great I would not expect much of a perf/watt improvement.

But a high temperature in a hotspot when the product is rated to run at those temps is a distraction. Total power output (watts) matters, hotspots barely do.

Just leave it at stock then they are designed to boost upto 95*C - I feel AMD should have maybe tried to communicate this better as loads of people are getting hung up on this 95*C thing when its working different to what you would normally expect - it's a hotspot by design no matter your reasonable level of cooling, not that its using so much power that your 420mm AIO is getting overwhelmed and that's the best it can manage.

 

[Author_25]

As long as it's designed to run at 95c I have no problem, it's just that it adds to the cost of an already expensive upgrade, and Intel there is more flexibility in cost such as DDR4

I guess there is a precedent to this, if I recall the 5000 GPUs had hotspots that ran this kind of temperature and as far as I know they aren't dropping like flies. GDDR6X perhaps isn't the best example...

I watched that video last night... Feels like the Intel 8th gen heatpaste debacle all over again. I wonder how long until we start seeing pre-delidded or lapped CPUs on sale with coolers adapted to sit lower on the socket

 

[DiscoDave]

Thanks for all the replies, everyone. If I can hold out I'll wait for the reviews of the Raptor Lake CPU's. Z790 mobo prices seem even more crazy than the AM5 ones though.
