It seems like ages have passed since we tested internal HDD, so we decided to introduce you one hard disk. Full name of this model, WD Caviar SE16 6400AAKS-00A7B0 reveals to eagle-eye so many things. This HDD has 16MB cache memory and 640GB capacity. Connection with motherboard is accomplished through SATA2 standard.

Most users are irritated with noise that their computer makes. Therefore, we can find on the market numerous “silent” solutions that will solve that particular problem. Yet, there is always “BUT”. With summer heats on the way it is just impossible to cool your processor with passive cooler. But, Cooler Master has a solution even to this problem.

Since the number of motherboards based on AMD 780G chipset gets bigger and bigger, we decided to compare them forthright and to identify possible differences. Popularity of this chipset is shown in accessibility of motherboard based on it, superb integrated graphics and few more useful options. This kind of systems are great for multimedia computers because 780G will provide for this type of machines enough performances and of course, like any ATi, good display of colors.

We get used to test fast RAM memories from Kingston Company. Hyper X brand was, until now, associated with fastest RAM modules. Still, Kingston decided to utilize this very recognisable brand on other Kingston products. So, thanks to that we were introduced to Kingston DataTravel HyperX USB flash memory. Of course, right from the start, we figured that we got one very fast device (brand name can tell you a lot), but we couldn’t know, how fast...

Radeon HD4800 series of graphics cards is real refreshment in these days. Every new generation of GPU brought a big shift in performances and ATi this time showed us that top model graphics chip (RV770) doesn’t have to be expensive. Based on experience from previous HD3850 and HD3870 models, we expected that new model HD4870 will dominate in middle-high class, with lower price and higher performances than other competitors. But, we were wrong… Tests showed something quite unexpected. Still, before benchmark results let’s see what new GPU offers.

During last year IDF Intel has shown to the auditorium two slides which previously initiated a lot of dust in IT media. The first was famous slide on which Pat Gelsinger unveiled that password he uses is „I hate AMD“, and the second was one on which Paul Otelini rendered that Intel produced 40.000.000 processors in 65 nanometers until that day, and that total result of all other manufacturers was 0! Each comment is redundant. It was understood even to AMD so it „stepped on it“, reducing the result for at least couple hundreds of thousands until the end of that year.
Brisbane is the name of the city used by AMD for marking of its first processor core produced in 65nm. Essentially, we talk about last in a row of revisions of well-known K8 core. Revision „G“, as it’s recognized by the experts, does not bring any alternations of micro-architecture itself. The question is about dual-core which was introduced to us on last summer representing SocketAM2 processor which has 512 KB of secondary cache by core and DDR2 memory controller. The only difference is aforesaid alternation of manufacturing process and two after-effects it brought. First is reducing of core dimensions itself, and second is reducing of thermal dissipation. Why and for whom these after-effects are significant? First, Intel was repulsed for the satisfaction to be praised as single manufacturer of processors in 65nm. Maybe it sounds banal, but believe us – it’s not. Second, by reducing core dimensions AMD is able to drastically increase production volume, which implies opening of maneuver space for further reducing of dual-core processors prices. After all, improving thermal characteristics will give additional impulse to AMD on notebook market, where this characteristic is crucial.
We received the fastest processors to test, which is produced by AMD in 65 nanometers. Athlon 64 X2 5000+ operates at frequency of 2.6 GHz. Nominal voltage is within the span of 1.25 to 1.3 V. Our exhausting testing has shown that processor operates pretty well at nominal frequency of only 1.1 V! Within this-like low operating voltages goes very low heating during testing and under the highest overload. Thanks to 65 nanometer technology, Brisbane processors with slightly lower clocks would operate stable and only with passive heatpipe cooling. This attractive option should be definitely tested in close future.

From indicated fact that K8 core did not suffered any alternations derives conclusion that we should not expect any alternations within performances regarding 90nm processors. The matter that AMD lovers were secretly admiring was better overclocking performances of Brisbane in relation to Windsor (the name of the core produced in 90nm). Our tests confirmed that real maximum which Brisbane may achieve within air cooling, is just above 3GHz. Conceptually, it is a question of result which could be achieved by some selected models of Windsor (classified in FX series). If time reveals that this overclock can be achieved by most of Brisbane processors, then we can be satisfied. On the other side, all those who were hoping for much higher frequencies will remain disappointed. However, they were hoping without any reasons, since perfection is only one variable in equation for an altitude of operating frequency. K8 was never designated to operate over 3 GHz. For more than that, we should to wait for K8L, known as „revision H“.
When we observe the development genesis of K8 core, it is obvious that AMD always created improvements within two phases. The existing core was only reduced within the first conquering of new production process, without any experiment. In second phase, the production process itself would be refined through additional technological advancements, thus it resulted with cold, even faster and more overclocked processors. Revision G is the first phase in the concrete situation. Revision H will be the second when K8 core would be drastically altered, and production process will be improved through implementation of Germanium, improving of SOI and DSL technologies. Considering all these, from the very first day of Brisbane occurrence we became restless waiting for Revision „H“. We hope that upcoming 4-5 months will pass like a wind.
