The Intel Core i7 2600k was a great edition in the Sandy Bridge processors, and it offers excellent performance for its price. This processor’s gaming and raw performance are not like the hardware we are getting these days, but still, it manages to give an excellent raw performance. One of the best things to consider for a low budget is its multiplier is factory unlocked, and you can get some extra performance from it. Those who don’t want to overclock can even go with 2600 because it’s slightly cheaper than this and offers the same performance. Some users might find it a bit expensive, but it makes sense to pay this price for its performance.

The semiconductor conductor technology used in this processor is 22nm, where you might already know that AMD is releasing processors and graphics cards of 7nm these days. This processor was launched in Q1 of 2011, while the company discontinued it and processed its last batch in Q1 2013.  It comes with a base clock of 3.40 GHz while on boost, it can easily hit up to 3.80 GHz, and still, you are allowed to push its clock rates. As most users consider these CPUs for some productivity or content writing-like work, I’m sure you can get excellent performance in multitasking applications with Intel hyperthreading technology.

One thing that might disappoint some users regarding this processor is its price, but it is worth it for its performance. Also, I found that the performance difference between this processor and i5 2500K is not that much, but it’s way more expensive than that CPU. This processor is great for games released before the last two years, but if you consider lowering the resolutions and other in-game settings, you can efficiently run them with this CPU. The same model from the last generation was much weaker as compared to this one, and that’s why I’m recommending this one.

Pros

  • Much Better
  • Supports Overclocking
  • Core CPU with Intel Hyperthreading support
  • Best Performance in Windows 7
  • Fully Unclocked Multiplier

Cons

  • Not compatible with the older motherboard.
  • Socket changed the third time with Sandy Bridge CPUs.
  • The base clock of this CPU is locked.

The next in our list is also from the Sandy Bridge architecture, but the Intel Core i7 2700K is slightly more powerful than the previous CPU and offers impressive performance. Some users reading this might find it expensive and think it isn’t worth spending this money on a second-generation processor. Still, this one is capable of giving a fantastic performance in games. Those who already own a processor from the first or second generation can upgrade to it as it’s a worthwhile upgrade. The good thing about it is it comes with four cores and eight threads and has Intel Hyper-Threading technology. Its performance in games is excellent, but the main reason to consider this gaming beast is its performance in multicore applications like rendering or internet browsing.

It’s a factory unlocked processor, and you can reach some new limits with it if you consider overclocking. However, you might need some good aftermarket coolers for it because the stock one doesn’t support overclocking at least above average. This processor’s overall gaming and productivity performance are good enough, and you can play modern titles at some reasonable settings and frame rates. Still, of course, it’s not going to give you performance like the current generation processors. Back in 2012, we saw much hyper of this processor because it’s only the one that offers this kind of performance, but with improvements in technology, we now have more powerful hardware for less price.

If you like to play games like Counter-Strike or DoTA 2 and are low on a budget, I recommend you go with this gaming beast. The MSRP is high, but the used version of this processor is available for a meager price, and you are most likely to buy that one. This processor is compatible with most of the LGA 1155 motherboards out of the box, and you don’t have to worry about the BIOS upgrade or other things. The only thing I would recommend regarding this is its performance difference compared to i7 2600k is not that much, and don’t forget to take a look at that one.

Pros

  • One of the fastest Sandy Bridge CPUs ever released.
  • Offers excellent overclocking potential.
  • Comes with Intel Hyper-Threading technology.
  • Old hardware but still supports modern games.

Cons

  • The integrated graphics unit is not very powerful.
  • Performance difference as compared to i7 2600k is not much.
  • This processor is way expensive for mainstream users.

There we end up with the Sandy Bridge processors, and we’ve got the next generation, which is better than the previous one and offers excellent value for its price. Yes, we have the Ivy Bridge Intel Core i7 3700k processor, which is way better than the i7 2700k and comes at the same cost. The cores and the threads remain the same, and it also comes with four cores and eight threads and supports Intel Hyper-Threading technology, which offers excellent performance in games and other applications. The things that changed between these processors are a generation gap with more transistors, better clock rates, and performance. Also, I7 3770k offers more overclocking potential, and you can easily push it to its new limits.

Like the current generation processor, it also got a 100 MHz boost in clock speed from the last generation and provided a base clock of 3.5 GHz. The turbo reaches up to 3.9 GHz and allows a little bit of overclocking with the stock cooler. While in reviews, we can see that the gaming performance of this processor is good enough, but we can’t expect something like what modern machines are offering us these days. Though if you make a little compromise on the graphics and the in-game settings, you can get decent performance from this hardware. Same as the other Intel processor, it also comes in two different variants where the one is the Intel Core i7 3770, and the other one is the K version, the one we have.

Overall, when we see them in terms of performance for modern games and applications, there is no doubt that they are one of the best processors for the LGA 1155 socket and what else we can expect from eight-year-old hardware. One thing to note is that the non-K version is slightly cheaper than the other one, and if you don’t consider overclocking, you are good to go with that one, but you need the K variant for overclocking. Intel Core i7 3770k comes with an Intel HD 4000 series graphics card, which might be the best for enthusiasts, but it comes with DirectX 11 and supports many games. Of course, you can’t play modern titles on it, but still, it supports some older games that you can consider playing on it.

Pros

  • Best Overall Performance
  • Improved Integrated graphics
  • Supports Direct X 11 API.
  • HD 4000 series supports low-quality games

Cons

  • iGPU still doesn’t support games.
  • Minor performance difference over last gen.
  • Upgrading from the 2nd gen doesn’t look worthwhile.

We’ve finished the expensive hardware list, and there we got something that budget users might love, and of course, it’s from Ivy Bridge. Yes, there is the Intel Core i5-3350P, which offers excellent performance in older games and some office base tasks, etc. Of course, I’m not saying this processor will max out some of the great titles, but we can still get some average performance if we do negotiations on game settings. This one is a mid-range processor in its time and has the same value, just like the i5 processors offer these days. If you only like to play games like Grand Theft Auto V or Counter Strike Global Offensive, you will be good to go with this hardware. Core I5-3350P doesn’t support overclocking or Intel hyperthreading technology, and its multiplier is locked.

The only reason I found to consider this processor is its performance for its impressive price these days. Intel Core i5-3350P comes with four cores and four threads and doesn’t offer any physical as I’ve mentioned before. The base clock of this CPU is 3.10 GHz, which is good, but on boost, it can easily reach up to 3.4 GHz with the stock cooler, and that’s amazing in this processor. The architecture used for its build is Ivy Bridge, and yes, it’s a 3rd generation processor built on 22nm technology. Those users who own an LGA 1155 motherboard that supports the 3rd generation can efficiently run this, but you might need a BIOS upgrade for some. The gaming performance of this processor is not that great, as we can see in the current generation i5 processor, but yes, it’s cheap, so we have to compromise on it.

Users who can’t afford a high-end processor from this generation can even go with this one if their user needs are not too much. From the list of old hardware, this processor offers excellent value for its price, and we can say it’s one of the best affordable CPUs for the LGA 1155 socket. One thing that might disappoint some users of this processor is the lack of integrated graphics, and you need a dedicated graphics card to run it. The main reason to mention this processor on the list is its low price because there are some other better options in the i5 series, but they are expensive.

Pros

  • Offers excellent value for its price.
  • Gives decent performance in games.
  • A very affordable choice for budget users.
  • Offers high clock rates.

Cons

  • Doesn’t supports hyperthreading.

The performance this processor offers for its price is no doubt best compared to the other alternatives, and I will recommend you go with this one. One thing that you might miss in this processor is the overclocking options, as its multiplier is not unlocked, which means no overclocking. Also, it is made for some servers, not primarily for gaming, so that you might notice the same low gaming performance, but that doesn’t mean it’s bad.

Pros

  • Very affordable price for its performance
  • Offers excellent value than its competitors
  • Supports Intel Hyperthreading technology
  • Four cores and eight threads are enough

Cons

  • No overclocking power
