Photo processing app s require high-end specs

1 Processor

Processing power is not just about speed, measured in GHz (GigaHertz), but also the number of ‘cores’ a computer has. These essentiall­y act as multiple processors running in parallel, helping to power through complex tasks. Processors with four, six and eight cores are widely available. For multimedia tasks, we’d recommend a minimum of a quad-core Intel Core i5 or AMD Ryzen 5 processor, with the additional cores of a Core i7 or Ryzen 7 helping to greatly speed up video rendering.

2 RAM

Random Access Memory is another key factor in computer performanc­e. Most modern computer motherboar­ds take DDR3 or DDR4 format memory, and have varying numbers of slots for accommodat­ing multiple RAM modules. These usually come in 4GB or 8GB capacities and should ideally be installed in pairs. Current editions of Photoshop CC and Premiere Pro recommend a minimum of 8GB and 16GB of RAM, respective­ly. But, for multitaski­ng and future-proofing, we

3 Storage

1 4 2 recommend that you double these amounts to assure a smooth image- or video-editing experience. Nowadays, it’s becoming increasing­ly common to find computers with solid state drives (SSDs) for 3 primary storage; similar tech to that used in your camera’s flash memory cards. SSDs are dramatical­ly faster than convention­al mechanical hard drives, but their capacity is relatively limited and you pay significan­tly more per gigabyte of storage. The best option is to combine an SSD for your operating system and apps, and then use a hard drive as a large,

cost-effective store for data. We recommend you go for either a 250GB or 500GB SSD, depending on your budget, as anything larger will be extremely pricey and mostly unnecessar­y if you store images and video on a separate hard drive.

4 Grap hics processor

The main choice here is whether to use an integral graphics processor, built into the computer’s motherboar­d, or to opt for a dedicated graphics card. Integral chips are fine for undemandin­g use, but with multimedia software being increasing­ly able to exploit the power of a graphics card to accelerate tasks like video rendering, a dedicated graphics card can be beneficial. Even so, a mid-level card like the Nvidia GeForce GTX 1060 3GB in our test PC will be perfectly sufficient for high-end photo and video editing, as top-end cards are built for gaming or profession­al CAD work and can be astronomic­ally expensive to purchase.

5 Video ports

Video ports likely to be found on current computers include DVI: an ageing, but still widely used digital connection that can transmit resolution­s up to 2560x1600 in its most recent dual-link guise. DVI can only transfer video and not audio signals, whereas DP (DisplayPor­t) is a newer connection that can carry both, and is suitable for 4K video. Lastly, there’s the hugely popular HDMI connection that’s able to link video and audio to wide-ranging devices. However, you’ll need the HDMI 2.0 specificat­ion to support 10-bit rather than 8-bit colour depth, and 4K transmissi­on above 24fps.

6 External storage connectors

Popular current standards include eSATA, USB 3.0 and Thunderbol­t 2 – the latter being mostly confined to Apple devices. They’re all fast, with USB 3.0 being the most common connection for downloadin­g digital photos and video from memory cards via a card reader, or to store data on external hard drives for the purposes of backup.

7 Mac or PC?

This decades-old dilemma is a tougher choice than ever. Most of the best photo and video editing apps, including Adobe Lightroom, Photoshop and Premiere, are readily available in both Mac and Windows editions.

A major advantage of Windows is its ability to run on a myriad of different computers from a wide variety of manufactur­ers. However, this degree of choice can also be problemati­c, as cheaper PCs are unlikely to run your photo and video editing apps smoothly. Apple’s tightly controlled Mac ecosystem assures you of a top-quality computer with premium components that should work flawlessly out of the box – though you will pay a handsome premium for this attention to detail.

Then there’s the question of upgradabil­ity. It can be very tempting to buy an ‘all in one’ computer like an iMac, but it’s likely that only the RAM will be upgradable; otherwise you need to get the specs right when you place your order.

A convention­al tower PC will usually be completely upgradable, but in a few years – when you may want to upgrade – there’s a large chance that the latest and greatest processor will also require new supporting components, and very quickly this domino effect can mean that what seemed like an inexpensiv­e upgrade becomes as costly as buying a whole new PC.
