It hasn’t even been a week because AMD unveiled its new HD 7790, based found on the images core which we’re almost certain furthermore powers the Xbox 720 — however, Nvidia has a fresh card launching now that’s meant to place a severe hurt about Sunnyvale’s newest GPU. Team Green’s modern GTX 650 Ti Increase is a main upgrade to the GTX 650 Ti — plus provided how synonymous the names are, that’s really a issue.
There are today 3 treatments labeled “GTX 650.” The vanilla GTX 650 without a suffix is based found on the GK107 GPU, meaning we don’t desire it except we do not have alternative choice. Current budget is $ 99 to $ 139. It’s obtainable in 1-2GB tastes, however has only 384 cores, 32 consistency units (TMUs) plus 16 raster providers (ROPs). Next up, there’s GTX 650 Ti. Current budget is $ 144 – $ 180. These cards have 768 cores, 64 consistency units, plus 16 ROPs plus come inside 1-2GB designs. Both of these cards have a 128-bit memory bus.
Now there’s the GTX 650 Ti Increase, with a release cost of $ 149 for 1GB cards plus $ 169 for 2GB cards. It has 768 cores, 64 consistency units, plus 24 ROPs. It involves Nvidia’s GPU Increase development as well as its maximum Increase clock is 11% high than the GTX 650 Ti’s standard base clock. It furthermore adds multi-GPU help (the GTX 650 Ti lacks that), plus has a 192-bit memory bus. Total memory bandwidth found on the Ti Increase is 1.67x high than the GTX 650 Ti’s, because of a mixture of high clocks as well as the wider bus.
Nvidia certainly should have branded the GTX 650 Ti Increase because the GTX 655. It shares the GTX 660′s help for GPU Increase plus multi-GPU designs. Like the GTX 660, it has 24 ROPs, that puts its fillrate at 23.5 gigapixels per next — almost double the GTX 650 Ti’s 14.8. By the time numerous providers receive performed with their own cards, the GTX 650 family may stretch from $ 100 to $ 220 — plus that’s more perplexing than it should be.
So how’s it compare to AMD’s HD 7790?
This isn’t a especially happy comparison for AMD. The GTX 650 Ti Increase has a significant benefit over the HD 7790 inside terms of total RAM, memory bandwidth, plus peak fill rate. Performance figures at PC Magazine bear out a few of the difficulties — when the HD 7790 is a big upgrade over the HD 7770, the GTX 650 Ti Increase is usually 20-30% quicker than the HD 7790. It also offers the multi-GPU plus GPU boost choices which AMD was crowing regarding only 4 days back.
AMD does have a some blessings. The $ 20 cost difference between your HD 7790 as well as the GTX 650 Ti Increase is very thin, however, it does result in the HD 7790 the cheaper way. AMD’s game way is arguably superior — when the GTX 650 Ti Increase comes with $ 75 inside game credit for 3 titles (World of Tanks, Hawken, plus Planetside 2), the HD 7790 comes with Bioshock Infinite. That can be enough to sway certain people, because the game is winning excellent critiques from numerous outlets.
AMD equally wins about total energy usage. Civilization V is regarded as a little quantity of titles where the HD 7790 plus GTX 650 Ti Increase tie at ~58 FPS (1920×1080, DirectX 11, 4x MSAA, High Detail), nevertheless the AMD card draws dramatically less energy, because shown under. Idle energy usage amongst the 2 is about similar. We ran certain fast comparisons between your 2 cards inside the newest adaptation of 3DMark plus again saw the 7790 drawing far less force — inside the Combined Test benchmark, the GTX 650 Ti Increase drew 185W, compared to the HD 7790′s 145W. The GTX 650 Ti Increase turned inside a high total frame rate (7.45 FPS compared to 6.56 FPS) yet should you break performance into watts per frame, AMD comes out ahead.
AMD’s last benefit is die size plus transistor count. The HD 7790 is a 2.08B transistor GPU at 160mm2. The GK106 which powers the GTX 650 Ti Increase is 2.54B transistors plus 214mm2. That signifies AMD probably pays less per die than Nvidia does, presuming both businesses are seeing equal yields.
At the finish of your day, you anticipate Nvidia’s performance figures can gnaw away at margins found on the HD 7790 series. The $ 149 release cost for the 1GB cards can be a tough sell; don’t be amazed when AMD slots 2GB cards into which place inside the not-too-distant future. The advantageous information is the fact that the HD 7790 has several area to maneuver because far because production margins plus is a much stronger card overall. The big winners total are customers, that are getting significantly greater goods at the same cost point.
