The general trademark of a manufacturer by which the consumer knows its products. A manufacturer can have multiple brand names. Some manufacturers license their brand names to other producers.
Product series:
Product series is a brand's indication, often indicated by round numbers like 3000, that identifies a group of products within one category that are technically very similar. We don't include product serie in the Icecat product title on a product data-sheet to avoid confusion.
Product name:
Product name is a brand's identification of a product, often a model name, but not totally unique as it can include some product variants. Product name is a key part of the Icecat product title on a product data-sheet.
Intel® Pentium® D Processor 820 (2M Cache, 2.80 GHz, 800 MHz FSB)
Article code :
The brand's unique identifier for a product. Multiple product codes can be mapped to one mother product code if the specifications are identical. We map away wrong codes or sometimes logistic variants.
The Central Processing Unit (CPU) or (micro) processor is the part of a computer where most calculations take place. In terms of computing power, the processor is the most important element of a computer system, so the performance of a computer is highly dependant on the performance of the processor. For quite some time the performance of a processor has been determined by the number of MHz the clock speed was, but nowadays clock speed doesn\'t have so much to do with the speed of the processor anymore. One of the best ways to compare different kinds of processors, is to look up benchmarks on the internet. Please be careful to buy a processor that is compatible with your motherboard, i.e. fits in the right socket.

Bottom line The Pentium D 820 is a great processor for those who like to multitask but who are also on a budget. It would not be my first choice for gaming, but if you are in the market for a fairly inexpensive, general processor, the Pentium D would be a great c...
The Pentium D Lineup Though we have already reviewed the first dual core Intel processor a while back in our Intel Pentium Extreme Edition 840 review, the real story may be these little puppies we are looking at today. The Pentium D processor line i...
Bottom line If you run only single threaded applications and only one application at a time, then that should tell you exactly what processor you need: the fastest single core CPU Intel or AMD make. But that isn’t always the case for most users. I would...
Dealing with current news means that we rarely have the opportunity to review old products and of course a comparison between the most recent products and those that came out several years ago can get a little problematic. But we’ve decided to push th...
It wasnt too long ago that we were all asking the question, "Should I go dual core?" Times have proven that dual core is the future and has clear benefits, which turned that question into, "Which dual core should I get?" Even if you are buying the lo...
Bottom line The 820 D proved to be a great CPU, especially given its cost. For $175US, you can have a great dual core cpu in your rig. I compared the 820 D to my Venice 3200+, which cost $270 when it was new. Just a year later, you get twice the power for less m...
The launch of dual-core AMD Athlon 64 X2 and Intel Pentium D/Intel Pentium Extreme Edition processors gave way to endless debates on numerous web-sites and hardware forums. Although these CPUs are not available in retail yet, the violent discussions of...
Bottom line In this review we tried to compare the processors from the mainstream pricing segment of the today’s CPU market. The situation here changed when Intel announced its dual-core Pentium D processors. The lowest model in this family working at 2.8GHz co...
Andrew B9.1The next wave of processors is finally here and Intels Pentium D 820 dual-core processor will definitely set the benchmark for the next generation of central processing units (CPUs). Intel considers their Pentium D 820 CPU one of their ent...

Although Intel manufactures a wide range of products, it is best known for its processors. And certainly, anyone who has used a computer has heard of Intel. So well skip the preliminaries and shoot straight into the review. :-) Some time back, we had...
Bottom line Overall performance with the D 820 is good. In most tests, it reported better performance than the P4 650. These were mainly CPU benchmark tests with SiSoft Sandra, PCMark05 or Prime95. But in games, the P4 650 reported higher framerates. However, if...
Preview: Today Intel launches the Pentium D line and the Pentium 4 Model 670. Model 820 of the D line is a 2.8GHz dual-core processor with a startlingly low price, and the P4 670 clocks at 3.8GHz. Can cheap dual-core Pentiums slow AMDs momentum?...
Intel now has so many different processor series to choose from it makes buying the right one a difficult job. The current LGA775 platform supports a number of processors featuring different clock speeds, front side bus speeds, cache and cores. The bas...
Bottom line The gaming performance of the dual-core Pentium D 820 is nothing spectacular, as these games are not designed to take advantage of this processor feature. Therefore, the dual-core Pentium processor was no faster than its slightly higher clocked single-...
Intel Pentium 4 670 and Pentium D 820 Another month passes and another couple of processors are released by either Intel or AMD. The last two months have been rather busy on the CPU front. Both rivals launched their own dual-core, consumer-level CPUs...
Bottom line What are the lessons to be taken away from the launch of two new Intel CPUs?. Taking the Pentium 4 670 first, its 3.8GHz clock speed, single-core design, and high power requirements when under load make it the last of a dying breed. Performance-wise...
Four no More After using the "Pentium 4" name for almost 5 years, Intel has finally introduced a new "Pentium". And no, its not the Pentium 5. Its the Pentium D, supporting Dual processor cores on a single CPU die. Try not to be confused by the "Cele...
Today we take a look at Intel’s Dual Core solution that comes in the name of Pentium-D. With us, we have the 820 which is the lowest-end dual core CPU from Intel clocking at 2.8GHz and has its Hyper-Threading and CPU Throttling features disabled. Wh...
Bottom line Looking at the benchmarks on previous pages, we see the Pentium D 820 performing very well in Video Encoding and 3D rendering. It also performs quite well in multi tasking which is what most of us do nowadays so the low scores in single everyday applic...
As mentioned earlier in the article we were not originally going to compare the 820 to the FX57/X2/EE due to the latter chips being much more expensive than the Pentium D however what was an afterthought was well worth including in the end. It is clear...
