Where did you get these numbers from? I Think the 7600x will be around 15k in CBR23, at least that's what one of the leaks suggested. Keep in mind though, the 13600k will be 60% faster at 24.5k

CPU comparison / processor comparison

Our processor / CPU comparison helps you to compare two CPUs. We use benchmark results from Cinebench R20, Cinebench R23 and Geekbench 5 as well as the FP32 raw performance (GFLOPS) of the iGPU.
www.cpu-monkey.com www.cpu-monkey.com

The 5600X clocks to about 4.3Ghz in R23, for the 7600X to be scoring 15K it would need to be clocking to around 5.4Ghz. Which is the cited clock speed of the 7600X.

which i suppose it could, it would be impressive for an R23 load if it did, i'm only estimating clocks that i think are reasonable, +10% would net it 4.75Ghz.

He has no idea about tuning AMD GPUs or CPUs. He didn’t even have SAM enabled initially. I pointed out several things to him via YT comments, including to enable SAM. He said if I made one more comment on his channel I’d be banned. A few days later he makes a video telling his viewers to enable SAM. You can safely disregard anything he says regarding AMD. That said, I’m sure he’s more knowledgeable on the Intel/Nvidia front.

Like i keep saying these people don't know what they are doing or talking about, and quite often they already have a mindset that biases them to concluding their incompetence to an AMD problem. Because they already have an attitude about that.
 
Look......

I have tweaked the crap out of my CPU, every individual core is tuned to with in a millimetre of what it can do, i have budget £90 32GB 3200MT/s RAM running at 3800MT/s on a £150 Motherboard

I have never had a PC that felt this smooth or responsive in games, or be this dependable, it has never put a foot wrong.

Right now i'm more than confident in buying AMD CPU's for the rest of my life, and i've had equal amounts of both vendors.

I'm a bit more sceptical when it comes to AMD GPU's, to be perfectly frank and honest, because a part of that solid reliability and just general great feeling PC is also the GPU, which is this one. https://www.techpowerup.com/gpu-specs/msi-rtx-2070-super-gaming-x.b7142

I'm happy to buy an AMD GPU these days, but i do feel more like i'm taking a chance with it.
 
On billibilli they are saying zen4 thermal throttles, 7950x tries to but can't maintain 5ghz all core as it bounces off the 95c thermal limit. 7600x gets up to 90c. This is using a 360mm AIO cooler on both chips. The 7600x pulls 120w and 7950x 230w, both chips stock. They're also saying Raptor lake runs cooler than zen4 (82c for a engineering sample 13900k on same 360mm AIO) - which I suppose makes sense, AMDs small chiplets means it has a higher heat density and iirc AMD said zen4 chiplets are even smaller than zen3 which means again more heat density

AMD Ryzen 7000 CPUs Reportedly Run Hot, Ryzen 9 7950X Hits Up To 95C Thermal Threshold at 230W, Ryzen 5 7600X Up To 90C at 120W

AMD Ryzen 7000 CPUs including the Ryzen 9 7950X are going to run really hot and consume the full package power as reported in a rumor.

Zen 3 behaves in the same way, it can boost to 5Ghz+ but its not doing that in Cinebench or any high load MT workload.

Which is why i don't think the 7600X is running at 5.4Ghz, not in R23 MT to score 15K.

I mean buying a GPU every 2 years when the new gen arrives with a CPU every 3 years.

I'm running a 5800X with a 3080, I'll probably buy a 4080 or 7800XT but pass over a CPU upgrade for another year.

If you buy a GPU every other generation so every 4 years then it always makes sense to buy a new CPU at the same time.

You can see if your current CPU has headroom and how much by lowering the resolution or graphics settings and see if fps increases.

That’s my upgrade strategy, I will see more performance gain by skipping a generation of CPU and GPU.

Yes/no

Don't forget that cache doesn't matter if the game already fits in the cache. For example csgo gains no extra performance on a 5800x3d, why? Because the game's main thread already fits inside the cache of a standard 5800x.

This means that when you have very little cache and you start adding more you see immediate benefits, but then as you keep adding more and more the benefit greatly diminishes- its like we keep adding more vram to graphics cards and it doesn't make them any faster unless your previous graphics ran out of vram in your games.

So while extra L3 cache would be nice, the 5800x3d is likely already not far away from the optimal amount of cache of games. You'll still see AMD pushing more L3 cache on EPYC, they're trying to 500mb of L3 on EPYC and the reason for that is because those chips are used for multithreading where you're running multiple application threads at the same time and you can have each in your cache at the same time.

Gamers don't need that much cache and there is no reason to add more cache than is needed for games on ryzen because the more cache you add the more of your cpu socket power limit you have to give to the cache which means less power for your CPU core so lower clock speeds. Cache also takes up space which means less space for your CPU core's transistors (I.e you end with a cpu that has less cores than it could have)

Thats not really how cache works.

It's for commonly repeted instructions, not to store bits of .exe's

A 7600X at stock running 8C hotter than a 5.3 all core 13900k on a 360 aio is very supprising.

Looks like many will be needing a beefy expensive cooler to go with the already pricey AM5 $300 entry level CPU which certainly adds to the already high platform costs.

Still it makes you wonder why AMD have chosen to go with a high 105w TDP on the 6 core chip when it'll still lose by a decent margin to a 12600k/13600/13400F.

A 13600k will cost $50 more according to the leaked pricing but it'll only need a decent $30 cooler at stock power whereas it's looking like you'll need a D15 or AIO for a 7600X to avoid throttling.

Its not about the size of the cooler, 105 watts of heat is 105 watts of heat, the difference is a larger chip has a larger contact area to transfer heat, so its more efficient at transferring that heat.

I have a 360 AIO on my 5800X, it doesn't do a better job at cooling it than a £40 air cooler, because its still just 100 watts, the chip its self retains more heat because its too small to get rid of it, a literal definition of a bottleneck.

So no, just put a £40 cooler on it, you're not going to get a better result by putting anything more expensive on it. (with in reason) i'm not being completely literal.

A larger/better cooler will still be more efficient at transferring the heat away from the base plate.

A lager cooler can soak more heat and remove it more efficiently, yes. but.....

Think of it like traffic flow, 4 lanes packed with cars at 70 MPH, reduce the lanes to 3 lanes, 2 lanes.... with the same volume of cars, what happens to the traffic flow behind the pinch point? it slows down, so behind the pinch point, or the bottleneck the volume of cars is retained for longer.

The pinch point, the point at which the 4 lanes become 2 is at the point between the CPU die cap and the heat spreader, it doesn't matter that 10 yards further down the road it opens up in to 12 lanes (the cooler), before they get there they are squeezed by 2 lanes.
