Chance to buy new P C.

So this P.C. just turns up in my living room. 3 years back the committee of my wife's charity (she's chairman) were all given new laptops. One chose a desktop, and now she's quit, it's been returned.

My current laptop is a HP with an AMD A6 quad core processor, 8 GB ram, 1TB HDD and a dedicated onboard Radeon R4 with 1GB dedicated VRAM. I run it to a 27" Acer K272HL. The returned PC is an Acer TC-105. AMD A10 6700 cpu, 6GB RAM, 1TB HDD, 2GB Radeon 7000 GPU & 24" Acer K242HL monitor (still a current model).

I use LR5 & Elements 14 for editing my wedding work. My HP's HDD has about 250GB free, but a lot more to be deleted. It's slowing down a bit because of it. If I bought the PC, would the GPU make it a lot faster than the HP, or would the HP's bigger RAM even things out? I fancy it, and it's probably worth £250.00 or more, though I'd get it cheaper. The downside is that everything is on my HP software wise, as is my image catalogue.

What are your thoughts.

I have no idea about AMD, but you have to be a bit careful with Intel cpus. Some that sound fast are not. I don't know about GPUs, but they can certainly make a big difference.

This is pretty accurate IME:

List of all cpus:

As far as RAM goes, it seems to me that 8GB is about the minimum for W7 through W10. However, if you have a spare slot in the Acer, adding memory could be quite inexpensive.

I have had machines with 8GB and 16GB ram. Honestly, what I find makes the biggest difference is the cpu speed (given by the link, not clock speed). However, I've never had a 'gaming' machine, so I don't know how a good GPU might compensate.

Just looking at that link, if the A10 is the A10 6700 APU, then it could be twice as fast as the A6, depending on exactly what cpu that is. IME cpus in the <2000 range are 'slow' and in the 6000+ are 'nice and quick', just to give you an approximate idea.

Thaks for that. Nice to know it's in-between.

No GPU will help performance in Lr 5, I'm pretty sure that wasn't implemented until Lr 6. I don't think there will be much if anything that makes use of a GPU in PsE either. As far as Adobe is concerned it is only the video editing programs that make much use of the GPU and then they seem to favour nVidia with CUDA processors. Personally I would probably favour which ever system has the better single core performance, since that is what will give the best interactive experience in Lr. Lr really only seems to use multiple cores when doing imports and exports, otherwise it is pretty much single core only where it matters. Even on import and export functions it seems as if six cores are optimum, with no performance gain above that. Also I would expect your storage system may well become a significant bottleneck during large batch import export operations.

Thanks Al. I do think the A10 has a higher clock speed. Going to put LR on it, and see how nippy it is. There's 4 USB 3 ports on it, on the front too, so it'll be fast on import. Al, would you know if my 70D is USB compatible? Thanks.

You will need a USB3 compatible card reader to make best use of the ports, otherwise you are simply stuck with the speed of the slowest component. I think the 70D is only USB2, but the newest camera I own is a 50D. Fortunately my Dell XPS system has a multi card reader built in, and it features CF too, so that's what I use.

Alan and Ejenner, CpuMark benchmarks are as follows:
A6 6310 = 2432
A10 6700 = 4601

Looks like the A10's virtually twice as fast as the A6. :-D

You can't just go by CPU scores. Motherboards (especially ones for laptops), will lower voltages of the CPU to help conserve power or to counter heat problems. Desktops will do this as well to lower heat or fan noise. Bus and RAM speeds influence overall system speed, as well as GPUs and HD speeds. But spec wise, it looks like the desktop has some nicer specs. Up to you if you'd like to have it as another image editing computer: as others have noted, upgrading GPU doesn't offer as much advantages in image editing as with video rendering. Another route for an older computer is to make it a streaming media server! Having a full OS, it can store and play any video format, and they can fully support different audio surround formats. If you had Photoshop/LR CC, it might be worth it to consider a Nvidia Quadro card to get 10bbc colorspace (assuming your display can support it too). Likewise, as a media server for a 4K TV setup, that might be time to upgrade video cards.

I agree, however, unless you are getting into highly specific applications, most machine will not be limited by RAM access speeds. I have used a number of laptops and desktops with different architectures and while sure, one cpu score double another does not mean that one machine will be twice as fast for everything, IME it is significant and is usually a primary factor in speed. Sure a desktop could well be faster than a laptop even with the same specs for cpu, RAM and SSD.

People should be aware that just because one machine has an i7 and another an i5, or A10 vs A6, does not necessarily mean one will be faster (or much faster) than the other. There is a huge variation across each.
