When Intel launched its Westmere-based line-up this past January, one of the more interesting models released was the Core i3-530. The big reason was its budget $120 price tag. But if there’s one thing that can make a budget chip interesting, it’s overclocking, and fortunately, there’s huge potential where this chip is concerned.
With each new processor launch, one thing that’s bound to prove faster are mathematical equations, which when all said and done, plays a massive role in a lot of our computing today. The faster an equation can be completed, the faster a math-heavy process can finish.
Sandra includes applications designed to specifically test the mathematical performance of processors, with the main one being the arithmetic test.
For raw multimedia performance, it’s hard to out-perform Intel. Well, unless we’re comparing a quad-core to a dual-core of course. Here, we see similar results to our ProShow Gold test, with the X4 635 proving to be just a wee bit faster than the i3-530.
Sandra 2009 Cryptography
Crypto is a major part of computing, whether you know it or not, and certain processes can prove slower than others, depending on their algorithms. User passwords on your home PC are encrypted, as are user passwords on web servers (like in our forums). Past that, crypto is used in other areas as well, such as with creating of unbreakable locks on files or assigning a hash to a particular file (like MD5).
In Sandra’s Cryptography test, the results are outputted as MB/s, higher being better. Although this is somewhat of an odd metric to go by, generally speaking, the higher the number, the faster the CPU tears through the respective algorithm, which comes down to how fast a password is either encrypted, decrypted, signed, et cetera.
As I mentioned in the intro, Core i3 models do not include the AES-NI instruction set that was introduced with Westmere. I don’t personally consider it an unfortunate loss, as the market support for it is currently rather slim, and even if that wasn’t the case, it’s not as though the vast majority of the market, especially those looking to purchase Intel’s lowest-end offerings, are the type to take advantage of it. Hopefully that changes in the future, as our security is truly paramount.
That all said, given the total lack of AES-NI, the results are rather expected. The i3-530 falls far behind, thanks to the apparent lack of benefit that HyperThreading brings here. It’s all about cores, unless you’re talking about AES, then at that point the absolutely only option is Intel’s Westmere-based Core i5’s.
Microsoft Excel 2007
Most, if not all, businesses in existence have to crack open a spreadsheet at some point. Though simple in concept, spreadsheets are an ideal way to either track information or compute large calculations all in real-time. This is important when you run a business that deals with a large amount of expenses.
Although the importance of how fast a calculation takes in an Excel file is, we include results here since they heavily test the mathematical capabilities of each processor. Because Excel 2007 is completely multi-threaded (it can even take advantage of an 8-Core Skulltrail), it makes for a great benchmark to show the scaling between all of our CPUs.
I’ll let Intel explain the two files we use:
Monte Carlo – This workload calculates the European Put and Call option valuation for Black-Scholes option pricing using Monte Carlo simulation. It simulates the calculations performed when a spreadsheet with input parameters is updated and must recalculate the option valuation. In this scenario we execute approximately 300,000 iterations of Monte Carlo simulation. In addition, the workload uses Excel lookup functions to compare the put price from the model with the historical market price for 50,000 rows to understand the convergence. The input file is a 70.1 MB spreadsheet.
Calculations – This workload executes approximately 28,000 sets of calculations using the most common calculations and functions found in Excel*. These include common arithmetic operations like addition, subtraction, division, rounding and square root. It also includes common statistical analysis functions such as Max, Min, Median and Average. The calculations are performed after a spreadsheet with a large dataset is updated with new values and must re-calculate many data points. The input file is a 6.2 MB spreadsheet.
Intel’s current CPUs can crunch through numbers like no one’s business, and thanks to that, the i3-530 appears in the middle of the pack, even well above the equal-clocked but quad-core X4 635.
