Best CPUs and processor deals from AMD and Intel in 2017

What makes a processor the best? Some would say it's the price tag, and if money were no object this might hold weight. Others suggest that it's the number of cores or overclockability that determine how high a particular central processing unit (CPU) ranks in a price/performance chart.

In reality, it's simply a matter of taste, only made worst by the plethora of other variables to be taken into consideration. Which is why this list contains a bit of everything; older processors, AMD APUs and even the odd Pentium.

You would be disappointed after handing over a small fortune to build a machine used exclusively for cranking out documents. At the same time, it would be an equally misguided decision to skimp on the CPU in your gaming rig just to save money.

In the end, it's not about achieving the best performance possible, but to do so and still meet a personalized budget. Certainly, if funds were limitless, we would all be rocking supercomputers.

Fortunately, there are plenty of less expensive options from both AMD and Intel focused on everything from word processing to gaming. With its latest 14nm Ryzen CPUs now released, AMD will look to shrink the price performance gap with Intel in what is shaping to be a vintage year for hardware fans.

With this list, we're focused purely on readily available desktop and server processors; laptop CPUs and non-x86 parts will be ignored. So without further ado, here are our pick, in no order of preference, of the best processors you can buy right now for your desktop PC.

AMD Ryzen 7 1800X

Finally! A worth rival to Intel's best

Processor Cores: 8 | Thermal Design Power: 95W | Clock Speed: 3.6GHz | Processor Socket: AM4 | Cache: 20.8MB

Stunning multi-core performance
Insane Price
Overclocking is touch and go
Temperatures are ‘unique’

If you are an AMD enthusiast (or just prefer rooting for the underdog), these are interesting times indeed. AMD has launched a series of processors - Ryzen - based on a new architecture (Zen) and obliterates its current generation of CPUs.

Ryzen finally moves AMD into the 14nm era making it far more competitive with Intel's Kabylake family. The fastest of the lot is the Ryzen 7 1800X which packs a whopping eight cores with 16 threads and a base clock speed of 3.6GHz. 

Its maximum turbo core speed is rather low at 4GHz which makes it unattractive should you want to push it further out of the box. However, with a low TDP, it has all the hallmarks of a great CPU, one that Intel's HEDT family firmly in its crosshair.

Intel Core i3-7100

Heavy lifting on the cheap

Processor Cores: 2 | Thermal Design Power: 51W | Graphics Controller: Intel HD Graphics 630 | Clock Speed: 3.9GHz | Processor Socket: LGA 1151 | L2 Cache: 3MB

Cheapest Kabylake Core chip
Supports faster memory
Best paired with newer board

If you want to do some heavy lifting but don't want to blow your savings on a piece of silicon, then check out this chip. The Intel Core i3-7100 is the cheapest Core processor based on the new KabyLake architecture, and you don't have to fork out a fortune for it.

Using a 14nm node, it reaches 3.9GHz with a 51W TDP; its dual-core/4-thread configuration should make for a decent gaming rig, and the 4K-capable Intel HD 630 GPU is clocked at 350MHz. Oh and it should make a fairly good overclocker as well.

True, you'll want to pair it with a motherboard with a decent chipset (Z170) in order to run faster memory (DDR4-2400), but that isn't necessary. It is not a K-model, and there are two SKUs, the 7100 (higher TDP and higher clock speed) and the 7100T (lower TDP, lower clock speeds) so make sure you choose the right one.

AMD Ryzen 7 1700

The cheapest Ryzen chip around

Processor Cores: 8 | Thermal Design Power: 65W | Clock Speed: 3.0GHz | Processor Socket: AM4 | Cache: 20.8MB

Fantastic value for money
Great overclocking potential

Meet the AMD Ryzen 7 1700, the cheapest Ryzen on the market. Built on a maturing 14nm node, it has a TDP of only 65W, the lowest of the trio of Zen-based CPUs.

Clocked at 3GHz, it shows its true colours with a 23% overclocking out of the box, compared to just 12% for the two other Ryzen parts. 

That means its boost clock speed - which is likely to raise its TDP to the same level as its more expensive siblings - easily surpasses their base clock speed.

The rest of the feature list remain the same with more than 20MB of cache, eight cores and 16 threads and support for DDR4.

As such, the Ryzen 7 1700 delivers one of the best value-for-money ratios on the market, especially if you are a non-gamer looking for sheer performance on productivity applications.

Intel Pentium G4560

Kabylake on a budget

Processor Cores: 2 | Thermal Design Power: 54W | Graphics Controller: Intel HD Graphics 610 | Clock Speed: 3.5GHz | Processor Socket: FCLGA1151 | L2 Cache: 3MB

Four threads rather than two!
Stunning value for money
May require new motherboard

Its predecessor, the Pentium G4400, was one of the best options at the lower end of the market, and the G4560 is a shoe-in replacement offering Kabylake architecture on a budget. The laws of supply and demand means that it is actually retailing for cheaper than the G4400 or the slower Celeron parts.

This chip sports 3MB of L2 cache, hits 3.3GHz on its dual-core, two-thread setup with a TDP of 54W. It doesn't have an unlocked multiplier like the G3258 though but its improved processor graphics (HD510) can support DirectX 12, 4K resolutions at 60Hz over DisplayPort which makes it great for a home theatre PC.

Note that there is a slower version (G4400TE, with a much lower TDP), which is great if you want an even quieter model to build your rig on. Costing less than half the price of a Core i3, it is a decent alternative if you're trying to put together a system without breaking the bank.

Intel Core i7-7700K

This quad-core one's a bit different

Processor Cores: 4 | Thermal Design Power: 91W | Graphics Controller: Intel HD Graphics 630 | Clock Speed: 4.2GHz | Processor Socket: LGA 1151 | L2 Cache: 8MB

14nm goodness
Opens up overclocking
Still just four cores
No vPro support

This is KabyLake, Intel's seventh Core generation, at its best and the one that AMD's Zen will have to contend with. The i7-7700K is the company's most powerful model set to replace the Skylake-based desktop processors in the short term.

We've got a pretty powerful processor boasting four cores, eight threads, 8MB cache, a base clock speed of 4.2GHz, a turbo-boost of 4.5GHz and an Intel HD Graphics 630 subsystem inside. 

All are step changes from the 6600K but at least the price didn't go up significantly. Overclocking is what may get some of us excited, however, as it's the distinguishing feature of the "K" models such as itself.

Pair that with a decent 100-series chipset, an oversized HSF and a couple of overclocker-friendly DDR4 memory modules, and watch it fly. 

And, although you'll want to pay close attention to that 91W TDP, 5.0GHz isn't a lofty goal with the 6700K.

Intel Core i5-7500

Expect this to be a best seller

Processor Cores: 4 | Thermal Design Power: 65W | Graphics Controller: Intel HD Graphics 630 | Clock Speed: 3.54Hz | Processor Socket: LGA 1151 | L2 Cache: 6MB

Supports vPro
Easy to overclock
No hyper-threading

There is a good reason why this Intel Core i5-7500 is likely to become one the best-selling processors in the Kaby Lake family.

It manages to deliver most of the performance/feature set of the Core i7-7700 at with a massive 40% discount.

Don't expect the performance delta to be that big though, more likely to be around 20% in most cases.

The three big differences are in hyper-threading support, in the base/turbo frequencies and in the amount of cache.

Manufactured using a 14nm process, the 7500 has four cores clocked at 3.4GHz with 6MB cache and a 65W TDP. It shares the same HD 630 graphics subsystem as the i7-7700 and offers support for vPro, something its bigger brother surprisingly doesn't.

best processor

AMD Athlon x4-860K

Ideal for upgrading an existing AMD rig

Processor Cores: 4 | Thermal Design Power: 95W | Graphics Controller: None | Clock Speed: 3.7GHz | Processor Socket: FM2+ | L2 Cache: 4MB

Highly overclockable
Cheap as chips
Still lags the competition
High TDP

Like most other AMD CPUs in this list, this is an old CPU which managed to remain relevant by combining decent performance with a superbly low price. Since this is an Athlon model, it doesn't come with a GPU.

It does however offer an unlocked clock multiplier which means that it is ideal if you want to overclock it.

It has all the necessary ingredients to be at the core of a great entry level computer. It is cheap, has four cores clocked at 3.6GHz (4GHz turbo) and, thanks to its 28nm manufacturing process, has a rather reasonable 95W TDP.

Expect it to roughly match a Skylake-based Core i3-6100T CPUs albeit with a far higher TDP (three times) but almost half the price.

Intel Xeon E5-2660

Best for tinkerers

Processor cores: 8 | Thermal Design Power: 115W | Graphics Controller: None | Clockspeed: 2.2GHz | Processor socket: FCLGA1011 | Cache: 20MB

Blazingly fast for certain tasks
Cheap as chips
Power guzzler
Xeon motherboards are pricier

There are many little-known secrets in the world of computer hardware. One of the best-kept is that, occasionally, data centers – globally operated by some of the biggest tech companies in the world – dump their processors as they upgrade to newer models. In effect, you probably can’t help but wonder what they do with all of their used-up goods. 

In most cases, they wind up on eBay or Amazon from second-hand sellers. From there, you can purchase these older, “slower” CPUs for a fraction of their going rate. 

The Intel Xeon E5-2660 v1 is one of them. Based on the tried (and still very much trusted) Sandy Bridge architecture, it is one of the best processors Intel has launched in the past decade. You can nab it for one-twentieth of what it would have cost to buy them new. 

Snag a pair of Xeon twins (you can get two for less than £100 from eBay) and you’ll be ready to assemble a hardy workstation rig like this one, complete with 16 cores, 32 threads and a whopping 40MB cache.

Sure, the technology is now obsolete and there's plenty to rile about. But if you're looking for the absolute bargain of the century and you know your way around, then, this CPU is probably the best Intel has to offer.
