Compare graphics cards nvidia vs radeon11/24/2023 Qualcomm processors are becoming more common in ultra thin and light laptops. Other manufacturers also make processors for laptops, including Rockchip and Qualcomm. Ryzen 3 and occasional A-series processors The following table helps explain the equivalent AMD and Intel processors. Read our guide to Intel processors for more information. Our reviews reveal any shortcomings with a given laptop's performance so it's always worth checking these first to help narrow down your choices. While there are differences in how the two brands' processors are designed, they can largely be considered like-for-like when making a buying decision, unless you have very specific needs with specialist software that works better with AMD or Intel for example. The equivalent AMD chips are Ryzen 3, 5, and 7. Upmarket desktops and laptopsĪt the higher end of the laptop market, where you start to see Intel Core i3, i5 and i7 chips, the differences can be more stark. An AMD E1, which can still be found on some laptops, is one of the slowest processors you’ll find on any computer and are typically best avoided, even if your needs only consist of basic office work, email or web browsing. You shouldn’t be short-changed whichever you choose.Īn AMD E2, for example, will perform similarly to an Intel Celeron or Atom processor. The good news is that at the low-end of the market, both companies manage similar performance. Here you’ll find AMD A4, A6, A9 and A10 processors that’ll compete with Intel Core i3, i5 and i7 laptop chips. You’re more likely to find an Intel processor in a laptop than an AMD one, although if you’re shopping around for a machine at around £400 or less, you’ll find plenty of AMD choices. Intel and AMD are the two main companies that make CPUs for laptops and desktops. Your choice of processor is the most important factor when considering how fast you need your computer to be and how much to spend. The CPU (short for 'central processing unit' and often simply referred to as a 'processor') is the brain behind everything your computer does. Whatever your budget, our lab tests reveal which models are worth your money and which aren't. This guide gives you a brief overview of the three brands, what they do and how they might impact your computer buying choices. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.These three companies produce the most important chips for the vast majority of laptops. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. Pixel rate is calculated by multiplying the number of ROPs by the clock speed of the card. Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. It is measured in millions of texels in one second. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). This figure is calculated by multiplying the total number of texture units by the core speed of the chip. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. The higher the card's memory bandwidth, the better the card will be in general. ![]() In the case of DDR memory, the result should be multiplied by 2 once again. It's worked out by multiplying the card's bus width by its memory clock speed. Memory Bandwidth: Memory bandwidth is the max amount of information (counted in MB per second) that can be moved over the external memory interface in one second.
