so I was looking at graphics card especially the r9 280x and 270x. When I was looking I noticed all of the different clock speeds and some are listed in ghz and mhz and was wondering what is the difference and if I should care what mesurment and if it mattered. Also some of the 280x/280 had a lower clock speed then some 270 and 270x, But where more than the 270s. So what should I go for.
1000 Megahertz is equivalent to 1 gigahertz, Similarly with hard drive space, 1000 megabytes is 1 gigabyte. to answer your question on Clockspeeds on GPU whether it matter when it comes to performance. the difference between X-Cards and non-X Cards are clockspeeds. for example a R9-270 is a underclocked R9-270X they are the exact same GPU with Different Clockspeeds, and Stream Processors, Again same goes to the R9-280. the R9-280 is an Underclocked R9-280X. the only difference is Stream Processors and Clockspeeds. also answering you question does measuring clockspeeds matter overall? yes and no. Yes because with a Higher Clockspeed you get more Performance but between AMD's GPU's it doesn't really matter so much. for example if you overclock a R9-280 you can get the same or better performance than an R9-280X. so realistically you never really have to grab an X-Card, you can save money grab a non-X card, overclock it and you'll get the same or better performance than the X-Cards.
1000mhz = 1ghz.
280/x are different from the 270/x as they have different gpu cores.
270< 270x < 280 < 280x < 290 < 290x
Buy the best you can with the budget you have. Read reviews on the given card if possible.
well I want to attempt to get all of this from my birthday and the holiday season. So I dont know the budget to go with.
Thanks that is very helpful.
Well without a $$$ figure to work with one could bounce around hypotheticals all day. Plus at roughly 6 month intervals there is a generation refresh or overhaul it will depend on when you buy as well.
Half truths here, really. A GPU with more shaders at the same clock speed is faster than one with fewer shaders, and a GPU with a faster clock speed is faster than than one with a slower clock speed and the same number of shaders. Being able to overclock is a very good reason to get as many shaders as you can reasonably afford, regardless of clock speed, because clock speed is the one variable you have control over.
