The AMD A10-7800 is a locked Kaveri quad core with (with 8x GPU core) base clocked at 3.5GHz with turbo up to 3.9GHz. If you need an unlocked processor, there’s the 3.4GHz variant 7700K and the 7850K which is clocked at 3.7GHz. The TDP is of 65w. This APU was out at the end of July, but we got the processor about 2-3 months ago. It couldn’t have come at the better time to be honest. In one corner, we have this APU and then there are processors from Intel stable- G3258 and the i7 4790K. Kaveri Vs. Haswell-refresh.

Okay, so comparing it with i7-4790K might not make sense for a  lot of people. But it helps to see how this accelerated processing unit (as AMD calls it) stands as it retails for $141.99. But then there’s the G3258– Intel’s 20th anniversary Pentium ‘love bug’ that is priced for $70- half of AMD A10 7800.

While Richland was based on 2-4 Piledriver architecture based core, Kaveri is based on Steamroller. It does support HSA features and AMD True Audio.

At the end of this review, most people’s point of view will be pretty much the same like previous AMD APU. But in some comparisons against its previous gen Richland core based A10-6800K, the green CPU/Red GPU team has some good work with it. This APU is based on 28nm fabrication process and uses FM2+ socket.

The newer Kaveri chips are as follows:

The 7600-7850K chips are Quad-core processors, whereas 78xx have 8x R7 series GPU cores. A6-7400K is the dual-core wielder, with 4x R5 series on-chip GPU. The upper Kaveri APUs are compatible with up to 2133MHz DDR3. What’s interesting is that some of these chips have variable TDP, depending on the clock speed (with and without Turbo) it runs at the time.

Like all paper specs, it sounds good but only when it’s put through its pace we would know how good or bad it is.

It gives me great pleasure every time I put up a review. It’s always good to appreciate the support that the manufacturers give from time-to-time to review their own products and others on behalf of the readers. Thanks to companies such as Asus, Gigabyte, Kingston, WD and Coolermaster who give me hardware support by updating my test rig no strings attached. Thumbs up to these guys! I would like to thank:

  • Gigabyte India for providing Gigabyte 890GPA UD3H Rev 1.0 motherboard
  • Asus India for providing Asus 990FX Sabertooth motherboard
  • Kingston Taiwan for providing hardware support with memory kits and SSD drive.
  • WD India for providing WD 300GB HLFS Velociraptor Hard Drive.
  • Coolermaster India for providing Coolermaster GX450 RS-450-ACAA-D3 Power Supply

The benchmarks used are as follows:

Compression Benchmark: Z7ip: Performance comparison between 1-8 Threads enabled Each compared with stock clocks between with and without Turbo.

Futuremark Benchmarks: PCMark 7 and PCMark 8 Benchmark: ‘Creative’ and ‘Work’ preset.

Processing Benchmarks: Cinebench benchmark 11.5  and 64 Bit Euler3D: Time Elapsed and Score Each compared with stock clocks between with and without Turbo.

Encoding Benchmarks: Handbrake Benchmark and H.264 encoding Benchmark Each compared with stock clocks between with and without Turbo.

Encryption Benchmark: TrueCrypt Benchmark: AES (in GB/s) and rest of the encryption type.

AIDA64 Benchmark: CPUQueen and CPUPhotoworxx

Game Benchmarks: Sniper Elite V2 and METRO 2033

All power saving and Turbo features are disabled and locked at 3.5GHz.

In single threaded 7-Zip test, Intel takes the lead. But for two and four threaded test AMD A10-7800 takes the lead. A10 6800K Richland APUs are quicker compared to these two processing units.

PCMark 7 Benchmark

Overall, G3258 takes the lead- even at stock.

There’s an improvement in productivity core in comparison with A10 6800K and it’s somewhat close to Intel G3258 at stock clock speed. Computation is where it takes a hit, but with Creativity and entertainment it does better than its predecessor.

Cinebench 11.5

In Cinebench 11.5, A10 7800 does better against Intel Pentium G3258. A10 6800K still a bit of a lead here. 

In Euler3D, both AMD APUs take a backseat in performance in comparison with the G3258.

Intel i7 4790K has better onboard GPU performance for METRO 2033, followed by AMD A10 6800K. But in comparison to G3258 in Sniper Elite V2, it takes the lead.

When it comes to low-end gaming, AMD A10 7800 does a pretty decent job. In comparison with the older AMD A10 6800K and handful of tests with G3258– it manages to hold its position.

The only advantage of an APU is an attached processing unit. If you slap a GPU in it with your newer build or sometime in the near future, that advantage is gone. But it also depends on the cost of the APU as well.

In India, AMD A10 7800 is not listed for sale anywhere. Not just in Amazon India or Flipkart, but also Prime ABGB and The IT Depot. The only ones that are listed is the AMD A10 7850K is between Rs. 12,930 to Rs. 13,100. Intel did a very good job in pricing its G3258 which is priced at Rs. 5,279/-. Bundle it with a decent motherboard and an aftermarket CPU cooler and you have a base rig where you can slap on a graphic card at some point. Intel G3258 provides incredible value overall if you think about it. It has a strong single-threaded performance. If you bundle with a good motherboard and cooler, you can get it to bit more than 4 GHz. AMD A10 7800 is a locked APU and that’s its handicap. Weird part is that 6800K is listed. Do Indian retailers don’t see the point in stocking AMD A10 7800? Your guess is as good as mine.

At the time of writing, AMD A10 7800 costs US$ 141.99 (INR 9,039/-) whereas G3258 costs $69.99 in Amazon US.
