Top 10 Processors for Personal
Computer
What makes a processor great? Some say it's how expensive it
is, while others suggest it's the number of cores or its overclockability that
determines the quality of a CPU. In reality, it's a matter of personal preference
backed by some hard numbers.
You would likely be disappointed if you shelled out a small
fortune just to build a machine that only ends up being used for typing up
documents. Likewise, thinking you could save some money by skimping out on the
CPU in your gaming rig would be an equally misguided decision.
The goal is to achieve the best performance possible on a
set budget. If money were no object, we would all be funding labs-on-a-chip
like IBM. There are plenty of options from the only two remaining x86
chipmakers, AMD and Intel, focused on everything from word processing to
gaming.
Realistically, though, until AMD releases chips that will
use the new Zen-based architecture and a 14nm manufacturing process, Intel has
the upper hand both in performance and value for money.
Moreover, you'll need to take into consideration the rest of
your PC's components. Pairing a top-end GTX 1080 graphics card with a cheap
processor simply wouldn't make sense. Whether you're building a budget PC or a
premium-priced server machine, you'll want to keep your parts consistent.
Overclocking, too, is worth your consideration. It's
completely understandable if you're apathetic towards the idea of pushing your
chip beyond its manufacturer-enforced clock speeds. However, if that's
something you think you might be interested in down the line, it's never too
early to start looking into overclock-friendly components.
With this list, we're focused purely on readily available
desktop and server processors; laptop CPUs, obsolete sockets and non-x86 parts
are not covered. Without further ado, here is the list of top 10 processors you
can find right now for your desktop PC.
1.
AMD A8-7670K
Price: $143.68 (amazon.com)
Processor Cores: 4 |
Thermal Design Power: 95W | Graphics Controller: Radeon R7 Series | Clock Speed: 3.6GHz | Processor Socket: FM2+ | L2
Cache: 4MB
If you are an AMD enthusiast (or like rooting for the
underdog), these are interesting times. AMD is about to launch a series of
processors based on a new architecture (Zen) which will obliterate the current
generation of CPUs. So prices are falling accordingly. The A8-7670K remains one
of the rare bright spots in AMD's lineup despite being more than two years old.
It is built on a newer 28nm manufacturing process which
kind-of explains why it has a 95W TDP - thermal design power, or a part's share
of your power supply's available Watts - despite a relatively high base and
turbo clock speed (3.6GHz and 3.9GHz). Its graphics performance is where it
shines thanks to an onboard GPU that is slightly more powerful than the Radeon
R7 240 GPU (six compute units, 384 shader cores, 757MHz GPU clock speed).
2.
Intel Xeon E5-2670
Price: $ $185.09
(amazon.com)
Processor cores: 8 |
Thermal Design Power: 115W | Graphics Controller: None | Clockspeed: 2.6GHz | Processor
socket: FCLGA1011 | Cache: 20MB
One of the best kept secrets in the world of computer
hardware is that, every now and then, data centres around the world, operated
by some of the biggest tech companies in the world, dump hundreds, if not
thousands of processors as they migrate to newer, faster and more power
efficient models.
When that happens, they usually end up on eBay or on Amazon,
where you can buy them for a fraction of their price (usually one tenth). The
Sandy-Bridge E5-2670 v1 is one of them; it's second-hand price is one-tenth of
its retail price. Grab a pair of them to construct a workstation rig that would
put Intel's current finest CPU to shame with a total of 16 cores, 32 threads
and 40MB cache.
3.
Intel Core i3-6100
Price: $117.01 (amazon.com)
Processor Cores: 2 |
Thermal Design Power: 65W | Graphics Controller: Intel HD Graphics 530 | Clock Speed: 3.7GHz | Processor Socket: LGA
1151 | L2 Cache: 2 x 256KB
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
i3-6100 is the cheapest Core processor based on the new Skylake architecture,
and you don't have to fork out a fortune for it.
True, you'll want to pair it with a motherboard with a
decent chipset (Z710) in order to run faster memory (2.66GHz), but that isn't
necessary. It is not a K-model, and there are two SKUs, the 6100 (higher TDP
and higher clock speed) and the 6100T (lower TDP, lower clock speeds) so make
sure you choose the right one.
Using a 14nm node, it reaches 3.7GHz with a 65W TDP; its
dual-core/4-thread configuration should make for a decent gaming rig, and the
4K-capable Intel HD 530 GPU is clocked at 350MHz. Oh and it should make a
fairly good overclocker as well.
4.
AMD Sempron 3850
Price: $41.35 (amazon.com)
Processor Cores: 4 |
Thermal Design Power: 25W | Graphics Controller: AMD Radeon HD 8280 | Clock Speed: 1.3GHz | Processor Socket: AM1
| L2 Cache: 2MB
At the other end of the spectrum is the Sempron 3850, one of
AMD's cheapest quad-core processors. It sports a Kabini core and is built on a
28nm process, which explains why its TDP only reaches 25W, almost one seventh
of the FX-9590.
Obviously, the fact that it runs at only 1.3GHz also helps a
lot. Add in the fact that it comes with an integrated AMD Radeon HD 8280 GPU
(basic, but decent) and you get something that's better than most
Baytrail-based systems at least. The best part though has to be the price; it
is cheap especially, as it includes the heat sink and the fan; that means that
you can envisage getting a motherboard bundle for less than Intel's cheapest
CPU. A shame that it has only one memory channel though.
Note that the Athlon X2 340, a different beast altogether (a
different socket and no GPU), is AMD's next cheapest processor, costing about
10 percent more.
5.
Intel Pentium G4400
Price: $59.99 (amazon.com)
Processor Cores: 2 |
Thermal Design Power: 65W | Graphics Controller: Intel HD Graphics 510 | Clock Speed: 3.3GHz | Processor Socket:
FCLGA1151 | L2 Cache: 3MB
Its predecessor, the Pentium G3258, was one of the best
options at the lower end of the market, and the G4400 is a shoe-in replacement
offering Skylake architecture on a budget. The laws of supply and demand means
that it is actually retailing for cheaper than the G3258 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.
6.
Intel Core i7-6700K
Price: $338.85 (amazon.com)
Processor Cores: 4 |
Thermal Design Power: 91W | Graphics Controller: Intel HD Graphics 530 | Clock Speed: 4.0GHz | Processor Socket: LGA
1151 | L2 Cache: 4 x 256KB
This is Skylake, Intel's sixth Core generation. The
i7-6700K, which cost just under $345 (£290, about AU$463), is the company's most
powerful Skylake model set to replace the Broadwell-based desktop processors in
the short term.
Here we've got a pretty powerful processor boasting four
cores, eight threads, 8MB cache, a base clock speed of 4GHz, a turbo-boost of
4.2GHz and an Intel HD Graphics 530 subsystem inside. 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.
7.
Intel Core i5-4690K
Price: $235.99 (amazon.com)
Processor Cores: 4 |
Thermal Design Power: 88W | Graphics Controller: Intel HD Graphics 4600 | Clock Speed: 3.5GHz | Processor Socket: LGA
1150 | L2 Cache: 4 x 256KB
There is a good reason why the Intel Core i5-4690K is among
the best-selling processors.
This Devil's Canyon part is one of the most, if not the most
affordable K-series processor from Intel's Core and as such can overclock
fairly easily with modest efforts. It has a base frequency of 3.5GHz with many
users reporting being able to hit 25% increase in speed using a decent
aftermarket HSF.
The 4690K doesn't come with hyper-threading, but for the
price it wasn't expected. The processor, bilt on the 22nm fabrication process,
packs 6MB of L2 cache, an 88W TDP and even an Intel HD Graphics 4600 on board
GPU.
8.
AMD FX-8320E
Price: $129.97 (amazon.com)
Processor Cores: 8 |
Thermal Design Power: 95W | Graphics Controller: None | Clock Speed: 3.2GHz
| Processor Socket: AM3+ | L2 Cache: 4 x
2MB
Meet the AMD FX-8320E; this is one of the cheapest
eight-core processors on the market.
Built on a mature 32nm node, it's clear why the FX-8320E has
such a high TDP (95W). Then again, maybe it's not an unusual spec given the
3.2GHz clock speed. Plus, when needed, it can even boost all the way to 4GHz.
But don't get your hopes too high, though. On most tasks,
the FX-8320E will be outperformed even by a modest Haswell Core i3. Where it
truly shines is when you throw multi-threaded jobs (encryption, encoding etc)
at it, where it can beat even the more expensive Core i5 parts. What's more,
many users have been able to overclock the chip easily using a non-stock heatsink
fan, some all the way up to 4.8GHz.
9.
Intel Core i7-5820K
Price: $407.00 (amazon.com)
Processor Cores: 6 |
Thermal Design Power: 140W | Graphics Controller: None | Clock Speed: 3.3GHz | Processor Socket: LGA 2011-v3 | L2
Cache: 6 x 256KB
With AMD ceding a bit of the limelight the past few years,
Intel has gone back to releasing products that require a new socket on a
quasi-yearly basis - great for sales, not great for customers. The Core
i7-5820K, a Broadwell component, is no exception. It uses yet another socket
aimed at the high-performance and server market.
What makes this little processor worth listing here is that
even though it has all six cores intact, it isn't priced outrageously. At $370 it's
really not a bad deal. Add in 15MB of cache, 12 threads and 28 PCI Express
lanes, and you get a compelling compute solution. Shame about the TDP, a
whopping 140W for a part that's clocked at 3.3GHz.
10.
AMD Athlon x4-860K
Price: $99.32 (amazon.com)
Processor Cores: 4 |
Thermal Design Power: 95W | Graphics Controller: None | Clock Speed: 3.7GHz
| Processor Socket: FM2+ | L2 Cache: 4MB
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.
