I dont know if I need a cpu with base clock only, or with base clock and turbo boost.

If CPU with 4 cores has baseclock of 3.5, no maximal boost clock, what does baseclock do when I use programs that dont need 3.5 ghz?
And what will the base clock do if I do videoediting and the editing needs more than 3.5 ghz cpu usage?

can someone explain it to me please?
 
Base clock is just that, the minimum CPU frequency that is GUARANTEED to run at for an indefinitely long task. Turbo boost is (*supposed) to be a temporary frequency boost that helps the computer get relatively short duration tasks (most consumer-level tasks) done more quickly. Higher frequency = better.

*On desktops especially, some/many non-OEM motherboard manufacturers will enable turbo boost to go on indefinitely, even though that's not Intel's intent. Since the motherboard manufacturer has control over the turbo boost duration (seconds), they can change this however they see fit.

What CPUs are you trying to decide between?

Ok, see, comparing AMD vs Intel isn't just a frequency comparison either.



Will you be using a graphics card, or are you specifically looking for a CPU that has integrated graphics that you'd use?

What country are you shopping in and what's your build budget?
Is this a pre-built system or are you assembling the components yourself?

I would buy a graphics card because of videoediting
Its a pre-build system
From the UK / or whole europe if they are able to ship
Budget is 600

The 8100 would be worse than the 9100F, and barely better than the Athlon. Just for comparison.

The 3300x is all around a far superior cpu, it'll hang with the big boys, especially when cooling allows for it good boost with PBO.

There's little point spending extra for the Vega graphics, if they won't be of any use.

So is the baseclock of the 8100 not efficient?

Just wondering why you are fixated on base clocks? There's 3 speeds with almost every desktop cpu, all sanctioned by intel/amd.

1. Idle: low power state during the period shortly after there's no user input, upto the time sleep modes kick in.

2. Base: The clocks used by intel/amd for testing purposes, minimum speed guaranteed under all core use. Generally at less than @ 30% cpu loads.

3. Turbo/Boost: Factory guaranteed attainable speed for at least 1 core, with slight speed drops with additional cores. Enabled default in all bios at factory optimized settings. Normal working speeds of the cpu with a stock or other appropriate fan.

So why the fascination with base speeds when turbo/boost is factory set/sanctioned as a normal working condition? Soon as you move the mouse or hit a key on the keyboard, you'll be seeing higher than @ 30% cpu load, so the bios will skip base clocks and go straight to turbo/boost performance modes. You will not generally ever see base clock speeds unless you go into bios and deliberately disable the factory set turbo/boost, in which case you paid extra for a stronger/faster cpu for absolutely no reason.

So what is the benefit of cpu´s that run with baseclock only?

You do not require the same level of cooling, because the cpu is never run at its potential. Cpus like that are usually run in server farms where pure cpu number crunching power is more of a benefit. Like 32 core Xeons running at 1.8GHz, they don't need speed, just core counts. That keeps the cpu far cooler than 32 cores at 4.0 GHz, which is wasted on software that needs cores not speed.

It's like buying a Ferrari that'll do 200+ mph, and using it to go through town to the store, in a 30mph zone.

A smaller, cheaper cooler is the ONLY benefit, the NON-BENEFITS far outweigh that lone consideration. Sheer lack of performance, inability to play certain games, most software taking far longer to load or work......

The CPU doesn't break just because it boosts. They are designed to do that. You want to be at boost speed or close to as much as possible.

Ghz is just one metric. A 4 Ghz singlecore CPU is crap today compared to a Quadcore 3 Ghz.
